Can Conductor scale to handle my workload? -Yes. Built at Netflix, battle-tested at internet scale. Conductor scales horizontally across multiple server instances to handle billions of workflow executions. +Conductor servers and workers scale independently. Use task domains, concurrency limits, persistence configuration, and metrics to match throughput and isolation to your environment.
Does Conductor support durable execution? -Yes. Conductor pioneered durable execution patterns, ensuring workflows and durable agents complete reliably despite infrastructure failures or crashes. Every step is persisted and recoverable. +Yes. Conductor persists workflow and task state, supports recovery after worker and infrastructure failure, and exposes retries, timeouts, pause, resume, and termination controls.
Can I replay a workflow after it completes or fails? -Yes. Conductor preserves full execution history indefinitely. You can restart from the beginning, rerun from a specific task, or retry just the failed step — via API or UI. +Conductor supports restart, rerun, and retry controls. Execution-history retention depends on configuration, and keepLastN intentionally removes older loop iterations.
Can Conductor orchestrate AI agents and LLMs? -Yes. Conductor provides native integration with 14+ LLM providers (Anthropic, OpenAI, Gemini, Bedrock, and more), MCP tool calling, function calling, human-in-the-loop approval, and vector database integration for RAG. +Yes. Conductor provides native LLM tasks, MCP tool discovery and calls, human approval, and vector workflows for RAG. See the maintained LLM orchestration guide for provider and capability details.
Why does Conductor separate orchestration from code? -Coupling orchestration logic with business logic forces developers to maintain determinism constraints manually — no direct I/O, no system time, no randomness in workflow definitions. Conductor eliminates this entire class of bugs by making the orchestration layer deterministic by construction. Workers are plain code with zero framework constraints — write them in any language, use any library, call any API. +Conductor keeps orchestration as a versioned, machine-readable graph while workers and built-in tasks perform business logic and side effects. This makes paths, inputs, policy, and task outcomes inspectable without constraining the language used for workers.
Isn't writing workflows as code more powerful than JSON? -It depends on what you mean by "powerful." In code-first engines, the workflow definition and your business logic live in the same runtime — which means the engine must replay your code to recover state. That forces determinism constraints on your business logic: no direct I/O, no system time, no threads, no randomness. Conductor separates these concerns. The orchestration graph is declarative (JSON), so it's deterministic by construction. Your workers are plain code with zero constraints — use any language, any library, call any API. You get the full power of code where it matters (business logic) without the framework tax where it doesn't (orchestration). +JSON keeps the orchestration graph machine-readable and versioned. Workers remain ordinary code, and built-in tasks cover common integration and control-flow behavior. Use validated runtime definitions when a service or LLM needs to select an approved plan at runtime.

Design principle #1 says it directly: agents collaborate -"even when they don't share memory, tools and context." - -This is the philosophical line between the two protocols: - -- **MCP exposes a tool's interface** so an agent can call it precisely (structured schema in, - structured result out). -- **A2A hides the agent's interior** and exposes only a capability surface (skills) plus a - conversational/task interface.

For each: what Conductor gives us for -free, and the current status of the A2A code. - -| # | Property | Guards against | Inherited from Conductor | A2A status | -|---|---|---|---|---| -| P1 | **Crash-safe persistence & resumption** | server restart / redeploy mid-interaction | Persistent execution store; durable decider queue; IN_PROGRESS system tasks re-evaluated on a new instance | **HOLDS** — resume state in task output; proven by T1 | -| P2 | **Guaranteed progress to terminal** (liveness) | agent down/silent forever; lost webhook | `timeoutSeconds` / `responseTimeoutSeconds` *when set* | **HOLDS** — absolute deadline + consecutive-failure cap in `execute()`; push backstop poll; proven by T4a/T4b/T5 | -| P3 | **Effectively-once side effects** | double-send after crash between send and persist | at-least-once + retry (the hazard, not the cure) | **HOLDS** (for cooperating agents) — deterministic, restart-stable `messageId` idempotency key; proven by T2/T3; boundary in §9.8 | -| P4 | **At-least-once execution + bounded retry w/ backoff** | transient network/5xx/429 | task retry (3×, linear backoff); HTTP RetryInterceptor; 429 `Retry-After` | **HOLDS** | -| P5 | **Idempotent, replay-safe callbacks** | duplicate / replayed push webhooks | — (our code) | **HOLDS** — IN_PROGRESS status-guard + constant-time token compare + token expiry; concurrent-callback race settled by the engine rejecting `updateTask` on a terminal task | -| P6 | **Durable multi-turn continuity** | losing the conversation across turns | persistent workflow variables | **HOLDS** (contextId/taskId surfaced in output, threaded by the workflow) | -| P7 | **Observability of in-flight state** | "is it stuck or working?" | task status, execution history, UI, metrics | **HOLDS** — `state`/`taskId`/`contextId` + `a2aStartedAt`/`a2aPollFailures` in output; Micrometer counters via the shared `Monitors` registry (`a2a_client_calls`, `a2a_client_poll_failures`, `a2a_rpc_errors`, `a2a_ssrf_blocked`, `a2a_server_requests`, `a2a_server_resumes`); MDC correlation keys (`a2aWorkflowId`/`a2aTaskId`/`a2aRemoteTaskId`/`a2aContextId`/…); structured warn logs | -| P8 | **Durable secrets at rest** | auth headers persisted in plaintext | Conductor secret references / external payload storage | **PARTIAL** — no header logging; **use `${workflow.secrets...}` / Conductor secrets for auth headers** rather than inline cleartext (usage guidance, not enforced) | - -The honest headline: every property now **HOLDS** except P8, which is a usage-guidance item -(don't put raw credentials in task input — reference Conductor secrets). The two that were the -real work — P2 (liveness) and P3 (idempotency) — are closed and tested. - -## 9.4 The hard one: exactly-once and the dual-write problem (P3) - -This is where most "durable" claims quietly fail, so it gets its own section. - -`message/send` is **not idempotent** in general — it can make the agent take an irreversible -action (charge a card, send an email, book a flight). The durable-execution hazard is the gap -between **performing the side effect** and **durably recording that we performed it**: - -``` -A2AWorkers.agent(): - 1. build message (messageId) - 2. a2aService.sendMessage(...) ← agent may now START IRREVERSIBLE WORK - 3. return TaskResult(taskId, IN_PROGRESS) - ── return to engine ── - 4. persist the returned task result ← FIRST durable record of step 2 -``` - -If the server crashes **between 2 and 4**, the agent has acted but Conductor has no record. The -task is still `SCHEDULED` in the store; the durable queue redelivers it and the worker method runs -again. The original implementation generated a **fresh random `messageId`**, so the re-send looked -like a brand-new message and the agent could do the work **twice**. - -You cannot eliminate this window from the client side alone — it is the same impossibility as -exactly-once delivery. What you *can* do is the industry-standard pattern (Stripe idempotency -keys, Temporal deterministic ids): **make the request carry a stable idempotency key so the -receiver can dedupe**, and make at-least-once + dedupe = effectively-once. - -### The key insight: a deterministic, restart-stable `messageId` - -The `messageId` must be: -- **identical across retries and restarts** of the same logical call (so a re-send is recognized - as the same message), and -- **distinct per logical invocation** (so a different loop iteration is a genuinely new message). - -Conductor's `TaskModel` gives us exactly the right stable identity (verified — all fields exist): - -``` -messageId = "a2a-" + sha256(workflowInstanceId + ":" + referenceTaskName + ":" + iteration) -``` - -- **Stable across retries:** Conductor task retry creates a *new* `taskId` but reuses the same - `referenceTaskName` and `iteration` → same key. (Basing the key on `taskId` would be wrong — - it changes per retry.) -- **Stable across restarts:** all three inputs are persisted before `start()` runs. -- **Unique per `DO_WHILE` iteration:** `iteration` differs → new key, as it should. -- **User-overridable:** if the caller sets `message.messageId`, honor it. - -This turns the deterministic id into a true idempotency key. Combined with at-least-once delivery, -an A2A agent that dedupes on `messageId` gets **effectively-once**. - -### The honest contract (this is what makes the claim hold) - -A2A does **not** mandate that agents dedupe on `messageId`. So the precise, defensible promise is: - -> Conductor guarantees a **stable idempotency key** and **at-least-once delivery** with a small, -> bounded duplication window. For agents that honor the key, the effect is **exactly-once**. For -> agents that do not, duplicates are minimized but not eliminated — because the side effect lives -> at the agent, true exactly-once is the agent's responsibility, as it must be in any distributed -> system. - -Overstating this (claiming unconditional exactly-once) is exactly how the claim *fails to hold*. -Stating the boundary is how it holds. - -### Optional hardening: recovery-by-query (capability-gated) - -For agents on A2A **v1.0** that support `tasks/list` with a `contextId` filter, we can close the -window further: default `contextId = workflowInstanceId`-derived, and on a re-run of `start()`, -**query for an existing task in this context before re-sending**; if found, resume it instead of -re-sending. This is an enhancement (v1.0 + agent support required), not the baseline. The baseline -is the deterministic `messageId`. - -## 9.5 Failure-mode catalog - -The matrix the claim must survive.

(Readable concatenation rather than a hash — the value is an opaque string; -debuggability wins and uniqueness/stability are what matter.) Stable across retries/restarts, -unique per iteration. The single highest-value change. - -**C2 — Liveness guards so nothing hangs (closes P2).** -- Track a **consecutive-transient-failure counter** in task output (e.g. `a2aPollFailures`). - In `execute()`, increment on a transient poll error, reset on success; after `maxPollFailures` - (default e.g. 10) → terminal `FAILED` with a clear reason instead of polling forever. -- Enforce a **deadline**: record the start time in output; if `now - start > maxDurationSeconds` - (configurable; sensible default tied to the push-token TTL, e.g. 24h) → terminal `FAILED` - ("A2A agent did not reach a terminal state within the deadline"). Do **not** rely on - `responseTimeoutSeconds` — each poll's `updateTask` resets it, so it never fires for a - polling task (verified). -- Have `AgentTaskMapper` default `timeoutSeconds`/`timeoutPolicy` to a finite, overridable - value rather than 0 (unbounded), as a backstop independent of our own deadline logic. - -**C3 — Durable push: backstop poll (closes the push hole in P2).** -Pure push (`isAsyncComplete=true`, no polling) hangs forever if the webhook is lost. For the -durable posture, push mode should **also poll at a slow backstop interval** (e.g. every few -minutes) so the task still completes if the callback never arrives — the webhook just makes it -faster. This means *not* setting `isAsyncComplete`, and instead returning a large -`getEvaluationOffset` while the push config is registered. Net: ~one backstop poll per N minutes -vs ~one per few seconds for pure polling — the efficiency win of push, without the liveness risk. -(Keep pure-push available as an explicit opt-in for users who accept the deadline as the only -backstop.) - -**C4 — Default `contextId = workflowInstanceId`. ❌ DROPPED (spec-correctness).** On reflection -this is spec-questionable: A2A `contextId` is **server-generated** — the agent assigns it on the -first response. A client pre-assigning a `contextId` on a *new* conversation can confuse strict -agents. The durability mechanism (P3) is the deterministic **`messageId`**, which needs no -client-chosen `contextId`. We keep the spec-correct flow: the agent generates `contextId`, we -capture it in output, the workflow threads it into the next turn. (The recovery-by-query -enhancement in §9.4 remains a v1.0-only optional follow-up.) - -**C5 — Streaming honesty + degrade-to-poll. ✅ SHIPPED.** Documented as **best-effort, not durable** -(in-memory aggregation is lost on crash). A stream that drops *after* yielding a `taskId` -degrades to `tasks/get` polling automatically (the aggregated non-terminal task → IN_PROGRESS → -`execute()` polls). A stream that yields **nothing** is treated as transient and retried (no -false COMPLETE). Durability-sensitive users should prefer poll/push. - -**C6 — Secrets at rest (P8). ◐ PARTIAL (guidance).** No header values are logged. The remaining -item is usage guidance — auth headers in task input are persisted; reference Conductor -**secrets** / `${workflow.secrets...}` rather than inline cleartext. Not mechanically enforced. - -**C7 — Callback idempotency + observability (P5/P7). ✅ SHIPPED.** IN_PROGRESS status-guard kept; -the engine rejecting `updateTask` on an already-terminal task settles the concurrent-callback -race. Counters (`a2aStartedAt`, `a2aPollFailures`) surfaced in output; structured warn logs on -transient poll failures with the failure count and bound. - -## 9.7 Proof obligations — the claim holds only if these pass - -Each maps to a property and must be an automated test that **injects the failure**. - -Each maps to a property and an automated test that **injects the failure**.

T1b exercises exactly that data boundary in CI. - -**Full-process proof (demonstrated).** The OS-level version now exists as a runnable demo — -`ai/src/test/resources/a2a/durable-demo/run-durable-demo.sh`: it starts a real persistent -(SQLite) Conductor + a remote A2A agent, places an order via a `AGENT` workflow, **`kill -9`s -the server mid-order**, restarts it on the same store, and the order resumes and completes.

There is no ambient state and no hidden mutation.

This is why [replay](durable-execution.md#replay-and-recovery) works unconditionally — restart a workflow from three months ago and it re-executes the same graph. Code-based workflow engines that embed orchestration logic alongside business logic cannot make this guarantee without imposing significant constraints on what your code is allowed to do (no random numbers, no system clocks, no uncontrolled I/O). +The same split keeps orchestration and implementation separate.

A JSON definition is data, and data is easy to generate, transform, and compose programmatically. Code is not. +Most engines require code changes, a compile, and a deploy before a new workflow can run. Conductor does not. A planner agent generates a definition as JSON, your code sends it to [`POST /api/workflow`](../documentation/api/startworkflow.md) with the definition inline, and Conductor validates, persists, and executes it immediately. The result is as durable, observable, and retryable as any pre-registered workflow. -### AI-native by design +### Inspectability and auditability -LLMs produce structured output.

Neither buffers the payload. - -The record is resolved by `fileId` and its `workflowId` must match the path — the persisted `FileModel` remains the source of truth for `storagePath`, which is never taken from the request. - -## Production requires a shared filesystem - -`CONDUCTOR` stores bytes on the server's filesystem. Signed or not, an HTTPS URL fixes *transfer*, not *storage locality*: behind a load balancer, node A writes the object and node B cannot serve the download. - -**This is the operator's responsibility, and it is a documented requirement, not something the server can paper over.** Any multi-node deployment using `type=conductor` must point `conductor.file-storage.conductor.directory` at a filesystem shared by every node — NFS, EFS, or a `ReadWriteMany` PVC. A single-node deployment needs nothing. - -Two things follow: - -- The server should log a warning at startup when `type=conductor` is configured, naming the directory and stating the requirement. It cannot detect replication itself, so a warning is the honest ceiling. -- `ConductorFileStorage` must commit atomically — write to a unique `.part` sibling, then `Files.move(..., ATOMIC_MOVE, REPLACE_EXISTING)`. This matters more on a shared filesystem than a local one, and it matters regardless because `getStorageFileInfo` treats bare existence as success: without an atomic commit an interrupted upload leaves a truncated file that `confirmUpload` marks `UPLOADED`. That hazard exists today. - -Anyone who does not want to run a shared filesystem should use S3, GCS, or Azure Blob. The deployment guide should say so plainly rather than presenting the four backends as equivalent. - -## Signed URLs: optional, default off - -A signature on the content URL is **not** about keeping the URL secret. OSS Conductor has no authentication, so anyone who can reach `/api/files/{wf}/{id}/download-url` can already obtain the URL and the bytes; a signature adds nothing there. Default it off. - -It earns its place for exactly one reason, worth recording so the option is not mistaken for security theatre: **it is how an auth-stripped transfer client gets authorized.** The SDK deliberately transfers signed URLs over a raw HTTP client with no Conductor credentials, cookies, or interceptors — `docs/design/file-storage.md` requires that, because a presigned URL is a bearer credential that must not receive Conductor headers. In a deployment that *does* front `/api/**` with auth, an unsigned content endpoint therefore leaves only bad options: exempt the path and it is fully public, or require auth and the raw client gets a 401. A signature is the third option — it substitutes for the auth header on that one path. - -So: implement it, default it off, document it as the switch to flip if Conductor is authenticated or internet-exposed. - -### Scheme, when enabled - -``` -{base}/api/files/content/{workflowId}/{fileId}?op=upload&exp=&kid=k1&sig= -``` - -Canonical string — newline-joined, fixed field order, version-prefixed so it can evolve: - -```text -v1 - - - - - - -``` - -Scheme, host, and port are deliberately **not** signed, so an ingress that rewrites the host does not invalidate the signature. - -Verification: look up the key by `kid` (unknown → 403); recompute and compare with `MessageDigest.isEqual` for constant time (mismatch → 403); check `exp > now` (expired → 403); check `op` matches the HTTP method (mismatch → 405 — without this a download URL is also an upload URL). - -Keys are a list: sign with the first, verify against all. That is the whole rotation story. When signing is enabled and no key is configured, startup fails — a per-process generated secret would be unverifiable on a sibling node and dead after a restart, which surfaces as intermittent 403s behind a load balancer. - -The repository has no HMAC helper today (`core`, `common`, and `rest` contain no `Mac.getInstance` or `MessageDigest.isEqual`), so this is a new, small, self-contained utility. - -## Absolute URLs and the base - -The URL must be absolute. Default: derive per request via `ServletUriComponentsBuilder`, with `ForwardedHeaderFilter` registered so `X-Forwarded-Proto` and `-Host` are honoured. That filter is **not** registered today — no `ForwardedHeaderFilter` or `forward-headers-strategy` anywhere in `server/`, `rest/`, or `docker/server/config` — so it is part of this work, and getting it wrong hands clients URLs pointing at an internal hostname. - -`conductor.file-storage.conductor.base-url` overrides it where the inbound request cannot describe the public origin. - -## Properties - -| Property | Default | Meaning | -|---|---|---| -| `conductor.file-storage.type` | `conductor` | Was `local`. | -| `conductor.file-storage.signed-url-expiration` | `60s` | Existing property; also the signature TTL when signing is on. | -| `conductor.file-storage.conductor.directory` | `${java.io.tmpdir}/conductor/files-uploaded` | Where bytes land. Was `conductor.file-storage.local.directory`. Must be shared across nodes in a multi-node deployment. | -| `conductor.file-storage.conductor.base-url` | *(derived from the request)* | Public origin override. | -| `conductor.file-storage.conductor.max-size` | `104857600` (100 MiB) | Rejected while streaming → 413. | -| `conductor.file-storage.conductor.signing.enabled` | `false` | See above. | -| `conductor.file-storage.conductor.signing.keys[n].{id,secret}` | *(required when signing is on)* | Verify against all, sign with the first. | - -## Security - -- **Size limits.** `FileUploadRequest` has no `fileSize` field (`fileName`, `contentType`, `workflowId`, `taskId` only) and `FileClient` sends none, so there is no declared size to check against. `max-size` is enforced while streaming and the transfer aborted once exceeded. `FileStorageException` already maps to `413` in `ApplicationExceptionMapper`, so the status is right for free. -- **Path traversal.** `storagePath` comes from the persisted `FileModel`, never the request, and is server-generated as `conductor/{workflowId}/{uuid}`. The storage implementation should still normalize the resolved path and reject anything escaping the base directory, so a corrupted metadata row cannot become an arbitrary-write primitive. -- **Concurrency.** Two uploads for one `fileId` race to the same `storagePath`; unique `.part` names plus the atomic move make the result one payload or the other, never a mix. -- **Exposure is unchanged from today.** The content endpoint is as reachable as the rest of `/api` — no more, no less. `LOCAL` had *no* authorization on its `file:` path either. Deployments that need real protection should enable signing, or use S3/GCS/Azure where the presigned URL model already applies. -- **When signing is on**, the URL is a bearer credential and inherits the existing rules from `docs/design/file-storage.md`: never logged, never in exception messages. It is replayable until `exp`, exactly as an S3 presigned URL is; single-use would need server-side nonce state and is not proposed. - -## No data migration - -There is no production usage of file storage today, so `LOCAL` is simply removed rather than aliased. What that touches: - -- `StorageType.valueOf(rs.getString("storage_type"))` in the MySQL, Postgres, and SQLite DAOs, plus Cassandra's JSON blob — all read back rows written by the same build, so nothing to convert. -- Seven `docker/server/config/*.properties` files set `conductor.file-storage.type=local`; they change to `conductor`. -- Test fixtures: `StubFileStorage`, `FileStorageServiceImplTest` (three assertions), `LocalFileStorageTest`, and `FileStorageIntegrationTest`'s `type=local` property. -- Module and class rename: `local-file-storage` → `conductor-file-storage`, `LocalFileStorage` → `ConductorFileStorage`, `LocalFileStorageProperties` likewise. - -A stale `type=local` in someone's config should fail at startup with a message naming `conductor`, not fall through to a missing-bean error. - -## Multipart - -`LOCAL` never supported multipart: `supportsMultipart()` is `false` in the SDK's local adapter, and `LocalFileStorage.generatePartUploadUrl` returns the same path for every part, so parts would have overwritten each other. - -`CONDUCTOR` can support it properly — the canonical string already reserves `uploadId` and `partNumber` — but it needs a dedicated SDK adapter, because `GenericHttpFileTransferAdapter.supportsMultipart()` is `false`. Until then, `CONDUCTOR` uploads are single-`PUT` and bounded by `max-size`. Not in scope; the signing scheme is designed so it does not have to change when multipart is added. - -## Testing - -Unit — storage: -- Atomic commit: an aborted stream leaves no object at `storagePath`. -- A `storagePath` escaping the base directory is rejected. -- `getStorageType()` returns `CONDUCTOR`. - -Unit — signing (when enabled): -- Round-trip sign/verify; tampering with each signed field fails. -- Expired `exp` → 403; unknown `kid` → 403; `op`/method mismatch → 405. -- Verification succeeds across a rotated key list; signing uses the first key. -- Changing scheme/host/port does not invalidate a signature. - -MockMvc — `rest`: -- `PUT` content by the owning workflow → `UPLOADED`; a `workflowId` that does not own the file → 403. -- Unknown `fileId` → 404. -- Over `max-size` → 413, no object left behind. -- `GET` content before upload → 400, matching `getDownloadUrl`'s existing rule. -- With signing on: unsigned request → 403; download signature used for `PUT` → 405. - -E2E — the acceptance criterion: -- The three failing cases pass against the **containerized** server with no bind mount, **using the current SDK**. -- All 11 still pass against the host JVM. -- `FileStorageE2ETest`'s class javadoc claims "a bind mount shares the server's storage directory with the host". No compose file in `docker/` mounts that directory; the claim is wrong and gets deleted. - -Neither unit nor MockMvc tests can catch this class of bug — both run in-process, where client and server always share a filesystem. Only the container e2e run distinguishes them, which is why it is the acceptance criterion. - -## Work breakdown - -| # | Change | Module | -|---|---|---| -| 1 | `StorageType`: `LOCAL` → `CONDUCTOR` | model | -| 2 | `conductor.file-storage.conductor.*` properties; startup warning about the shared-filesystem requirement | `core` | -| 3 | `ConductorFileStorage`: HTTPS URLs, streaming read/write, atomic commit, traversal guard | `conductor-file-storage` (renamed) | -| 4 | `GET`/`PUT /api/files/content/{workflowId}/{fileId}` | `rest` | -| 5 | `ForwardedHeaderFilter` + base-URL derivation | `server` | -| 6 | Optional HMAC signing: utility, config, verification filter | `core`, `rest` | -| 7 | `type=local` fails fast with a message naming `conductor`; update seven `docker/server/config` files and the test fixtures | `server`, `docker`, tests | -| 8 | Unit + MockMvc tests | `core`, `rest`, `conductor-file-storage` | -| 9 | Docs: `advanced/file-storage.md`, `api/files.md`, narrow the direct-transfer goal in `design/file-storage.md` | `docs` | -| 10 | *Optional later:* `ConductorFileTransferAdapter` with multipart | `java-sdk` *(separate repo)* | - -1–9 are one server PR, and the e2e assertions flip green on that PR alone — no SDK change needed. 6 can be deferred without blocking anything. 10 is a follow-up. - -## Compatibility - -| Client | Result | -|---|---| -| Current SDK, `CONDUCTOR` backend | Works via `GenericHttpFileTransferAdapter`, co-located or not. | -| Current SDK, S3/Azure/GCS | Unchanged. | -| Existing `type=local` config | Fails at startup with a message naming `conductor`. | - -The workflow-visible contract (`conductor://file/`) does not change, so no workflow definition or worker is affected. diff --git a/docs/design/file-storage.md b/docs/design/file-storage.md deleted file mode 100644 index 44fecd6a03..0000000000 --- a/docs/design/file-storage.md +++ /dev/null @@ -1,118 +0,0 @@ -# File Storage Design - -## Status - -Implemented by the workflow-scoped File API in Conductor and `FileClient` in the Java SDK. - -## Goals - -- Keep binary payloads out of workflow JSON. -- Make every file operation carry workflow context. -- Represent files in workflow data as opaque `conductor://file/` strings. -- Transfer bytes directly to storage without proxying them through Conductor. -- Support retryable, repeatable uploads and crash-safe downloads. -- Keep provider protocol details out of worker code. - -## Non-goals - -- Smart file objects that the task runner discovers and uploads implicitly. -- A public SDK storage-backend extension point. -- Forwarding Conductor credentials to object storage. -- Treating GCS signed PUT uploads as a resumable multipart protocol. - -## Components - -```text -Worker - | - | FileClient + workflow ID + opaque handle - v -Workflow-scoped File API - | - +--> FileStorageService --> FileMetadataDAO - | - +--> FileStorage --> signed URL / storage metadata / multipart mutation - -FileClient -- provider-signed request --> S3, Azure Blob, or GCS - -FileClient -- raw HTTP request --> Conductor content endpoint --> Conductor-managed filesystem -``` - -The server decides identity, ownership, storage location, URL lifetime, and upload state. -`FileClient` orchestrates the workflow API and byte transfers.

Design rationale - -- **Why delete rather than repair the test.** The test's sole purpose is to assert that - `backfillLegacyAgentExecutionClassifiers` exists and stamps a version into workflow - metadata. The reviewer has decided this method should not exist. A "repaired" test - would necessarily either (a) re-assert the forbidden method, or (b) test unrelated - behavior under a misleading name. Both are worse than deletion. Deleting the test - removes the unwanted contract cleanly. -- **Why remove the production code too.** Leaving a private, never-invoked method plus - its private helpers and constants would be dead code. `reindexAgentExecutions`, - `backfillVersionOf`, the two constants, and the `IndexDAO` field exist only to serve - the backfill; with the backfill gone they are unreachable. Removing them keeps - `AgentService` free of dead code and honors the "do not add it back" instruction in - spirit as well as letter. -- **Minimality.** Nothing outside the symbols in §5 is touched.

A2A (Agent2Agent) is the open protocol agents use to talk to each other over HTTP. With Conductor it works in both directions: a workflow can call a remote A2A agent as a durable step, and a Conductor workflow can be exposed for any A2A client to discover and invoke. Either way, Conductor records the handoff and its result.

An eval is a repeatable test for an agent. It replays a representative request against the agent and asserts on what the agent actually did, not only on the text it produced: which tools it called and with what arguments, how it routed between agents, which guardrails fired, and how the run ended. Run evals before promoting a new agent version, the same way you run tests before shipping code.

+ +Evals answer a release question: did the agent take the intended path for a representative scenario?

You can bring an agent authored in another framework, such as OpenAI Agents, LangChain, LangGraph, or Google ADK. You keep the agent object your framework defines, and the Conductor SDK compiles and runs it as a durable Conductor execution. This page is the reference: which frameworks and languages are supported, how a framework agent becomes a deployable Conductor Agent, and where the maintained examples live for each pairing.

A guardrail is a check that runs as part of the agent's execution, at the point where something could go wrong. It can validate an incoming request, constrain what the model returns, block unsafe tool arguments, or hold a consequential write until a person approves it. Because each guardrail is a durable step in the run, its verdict is recorded alongside everything else the agent did.

+ A request passes input and output guardrails around an agent; a tool-input guardrail and human approval protect a consequential write. +
+ + Place the control + Put policy at the input, output, or tool boundary where it is enforceable. + + + Choose the outcome + Retry, fail, repair, or pause for a reviewer with a durable record. + + + Design human review + Use a durable approval point before an email, payment, command, or write. + +
+
+ +Use guardrails with **Conductor Agents** authored through the SDK. For a declarative workflow built directly from `LLM_CHAT_COMPLETE`, MCP, `HUMAN`, and control-flow tasks, compose the same policy explicitly with schemas, `SWITCH`, `JSON_JQ_TRANSFORM`, and `HUMAN`. See [Durable Adaptive Graphs](dynamic-workflows.md) for that pattern. + +## Choose the closest enforcement point + +| Need | Put the control here | Typical action | +|---|---|---| +| Reject unsafe user input before the model sees it | Agent input guardrail | Block or return a safe response | +| Keep a model response within policy | Agent output guardrail | Retry, terminate, repair, or ask a reviewer | +| Prevent a dangerous side effect | Tool input guardrail | Reject before the tool runs | +| Validate data returned by a tool | Tool output guardrail | Stop, repair, or escalate | +| Require review before a consequential action | Tool approval or a `HUMAN` task | Pause until an operator decides | + +Tool-input guardrails are the critical boundary for writes. Do not rely on prompt instructions alone to protect a database mutation, shell command, payment, email, or GitHub write. + +## Guardrail types + +Conductor Agent definitions support four guardrail implementations: + +| Type | Best for | Execution shape | +|---|---|---| +| Regex | PII patterns, formats, allowlists, known dangerous strings | Deterministic server-side check | +| LLM | Tone, groundedness, policy interpretation, semantic quality | A second model evaluates a policy at temperature zero | +| Custom | Domain policy that needs application state | A registered Conductor worker | +| External | A centrally managed policy service | An existing worker selected by name | + +Regex guards run in `block` mode by default: a pattern match fails the check. Use `allow` mode when the content must match at least one allowed pattern, such as a constrained output format. Keep regexes narrow and deterministic; an allowlist for structured tool arguments is usually better expressed as a custom guardrail that parses the arguments by field. + +An LLM guardrail receives the candidate content and a policy, then must produce a JSON pass/fail decision. Treat it as a semantic check, not a replacement for deterministic access control. Do not send credentials or raw sensitive records to an LLM judge; validate a redacted representation instead. (Note: using `LLMGuardrail` with the Python SDK requires the `litellm` package: `pip install litellm`). + +Custom and external guards become `SIMPLE` tasks. Register their task definitions and run an idempotent worker before deploying the agent; otherwise the guardrail task cannot be completed. + +## Outcomes on failure + +Every guardrail declares an `onFail` policy: + +| Outcome | Behavior | +|---|---| +| `retry` | Add the failure feedback to the conversation and let the model produce another attempt, up to `maxRetries`. | +| `raise` | Terminate the agent execution as failed. Use for non-negotiable policy violations. | +| `fix` | Accept a corrected `fixed_output` from a custom guardrail. | +| `human` | Pause at a durable review step; the reviewer can approve, edit, or reject the output. | + +Use `retry` only when another generation could plausibly satisfy the rule. Regex and LLM guards are validation checks, not rewriters; use a custom guardrail when a deterministic repair is required. A human outcome applies to output review, not input validation. + +## Example: protect a write-capable tool + +This Python Agent SDK example blocks card-number-shaped text before an email tool can run. The same `RegexGuardrail` can be attached to a tool's output when a response must be checked before downstream use. + +```python +from conductor.ai.agents import OnFail, Position, RegexGuardrail, tool + +no_card_data = RegexGuardrail( + patterns=[r"\b(?:\d[ -]?){15}\d\b"], + name="no_card_data_in_email", + position=Position.INPUT, + on_fail=OnFail.RAISE, + message="Refusing to send payment-card data by email.", +) + +@tool(guardrails=[no_card_data], approval_required=True) +def send_email(to: str, subject: str, body: str) -> dict: + # Invoke the approved mail integration here. + return {"status": "sent", "to": to} +``` + +This has two independent controls: the guardrail rejects unsafe arguments before the tool call, and `approval_required=True` creates a human decision point for an otherwise acceptable write. The tool should still be idempotent because retries and ambiguous network failures can occur around external side effects. + +## Bound what the agent can do + +Guardrails are one layer of a larger policy boundary: + +- Define tool input and output schemas so malformed arguments are rejected before execution. +- Set `maxCalls` per tool, `maxTurns` per agent, and task or agent timeouts to bound work and cost. +- Use the plan-and-compile path's known-tool allowlist to reject plans that reference undeclared tools. +- Restrict multi-agent handoffs with `allowedTransitions`, and require declared tools with `requiredTools` where the process depends on a mandatory check. +- For CLI/code execution, use a small command allowlist, disable shell execution unless necessary, and set a short timeout. +- Declare credentials on the agent or tool so they resolve at execution time. Do not pass secrets in prompts, workflow inputs, or ambient worker environment variables. +- Use `maskedFields` to redact sensitive input or output fields from execution history and the UI. + +For direct workflow definitions, make the same constraints visible in the graph: validate the model plan, branch only to allowlisted tasks, cap `DO_WHILE` and `FORK_JOIN_DYNAMIC`, and put a `HUMAN` task before an external write. + +## Verify the guardrail itself + +Test both a passing and a failing case. A good release gate verifies that: + +1. Unsafe input never reaches the tool. +2. A blocked output cannot reach a caller or a write task. +3. The retry budget stops when exhausted. +4.

This page. +A **Conductor Agent** is an agent you author in code and register on the server. You build it with a Conductor SDK, or bring it from a supported agent framework, and Conductor compiles it into an ordinary workflow definition. Because the compiled agent is a workflow, every LLM call, tool invocation, wait, retry, and branch is visible in the UI and API, and the agent composes with everything else a workflow can contain: other tasks, branching, schedules, human approval, and cancellation. Conductor Agents are available in Python, Java, TypeScript/JavaScript, and C#. -Both values drive the same `AGENT` task type with one consistent input/output contract; the branch is chosen per task by `agentType`. +Conductor Agents are one of two ways to build AI behavior. The other is a [declarative AI workflow](llm-orchestration.md), where you place LLM, MCP, and control-flow tasks directly in the workflow definition. Choose the declarative path when the orchestration itself is what you are building. Choose a Conductor Agent when the agent logic lives in code and you want to run it inside a durable process. +## Server requirement -## What it is - -With `agentType: "conductor"`, the `AGENT` task runs a registered agent on Conductor's embedded agentspan runtime instead of calling out to a remote agent. Like the A2A branch, it is **non-blocking**: a fast reply completes immediately; a long-running run moves to `IN_PROGRESS` and is polled at a cadence (no worker thread is held), so the call survives a server crash, restart, or redeploy and resumes from persisted state. - -This branch requires the AI integration, enabled with: +Before deploying or invoking a Conductor Agent, enable the AI integration on the server: ```properties conductor.integrations.ai.enabled=true ``` -On a deployment without it, the runtime bean is absent and any `agentType: "conductor"` task fails terminally with: +The deployed-agent control plane and `agentType: "conductor"` execution mode are unavailable when this property is false or omitted. -``` -Conductor agents require conductor.integrations.ai.enabled=true -``` +## Lifecycle +Every Conductor Agent moves through the same five operations, and the names below are the SDK verbs you will see in code: -## Task input +1. **Create**: define the agent in code, from the SDK's own `Agent` class or from a supported framework object. +2. **Plan**: inspect the workflow graph the agent will compile to.

During development, `run` compiles and runs it in one step. In production, workflows invoke the deployed agent by name through an `AGENT` task. -The conductor branch parses its task input as a `ConductorAgentRequest` — an `AgentStartRequest` (the same DTO `POST /api/agent/start` takes) plus four AGENT-task-only orchestration fields for resuming a run and bounding how long it polls. Fields specific to the A2A branch (`agentUrl`, `streaming`, `pushNotification`, `headers`, `contextId`, `taskId`, `parts`, `message`, …) don't exist on this contract and are ignored here. +In short: use `run` while you iterate, then `deploy` and `serve` so workflows and other callers can start the stable deployed version. -| Field | Type | Meaning | -|---|---|---| -| `agentType` | String | Must be `"conductor"` to select this branch. | -| `name` | String | **Required** on a fresh start.

The latest version is used when omitted. | -| `prompt` | String | **Required** on a fresh start. The single prompt field — no fallback chain. | -| `sessionId` | String | Optional. Associates the run with an existing conversation/session. | -| `runId` | String | Per-execution isolation key for stateful agents. When set, every worker tool task is routed to this domain so concurrent instances of the same agent don't cross-talk. | -| `context` | Map | Extra context values passed to the run. | -| `media` | List\ | Media references attached to the prompt. | -| `agentConfig` | AgentConfig | Inline agent construction details. Mutually exclusive with identifying the agent by `name`/`version`. | -| `framework` | String | Framework identifier for foreign agents (e.g. `"openai"`, `"google_adk"`). Null for native agents. | -| `rawConfig` | Map | Raw framework-specific agent config. Used when `framework` is non-null. | -| `skillRef` | Map | Reference to a server-registered skill package. Used with `framework="skill"` when the caller wants the server to resolve the raw skill config from the skill registry instead of sending it inline. | -| `timeoutSeconds` | Integer | Per-call timeout override (seconds). Applied server-side to the workflow definition. | -| `idempotencyKey` | String | Client-supplied idempotency key. If omitted on a fresh start, the conductor branch fills in a deterministic, restart-stable key itself (see [Durability](#durability)). | -| `static_plan` | Map | Optional deterministic plan for `Strategy.PLAN_EXECUTE` harnesses — replays a recorded plan instead of running an LLM planner. Note the wire key is `static_plan` (snake_case), not `staticPlan`. | -| `executionId` | String | When set, **resume** an in-flight run instead of starting a new one (see [Human-in-the-loop](#human-in-the-loop--resume)). | -| `pollIntervalSeconds` | Integer | Poll cadence while the run is not terminal. Default 5. | -| `maxDurationSeconds` | Integer | Absolute deadline (seconds) for the run to reach a terminal state. Default 86400 (24h). | -| `maxPollFailures` | Integer | Consecutive transient poll failures (executor unreachable) tolerated before failing terminally.

Choose a deterministic regex guardrail for format, PII, and known-dangerous patterns; use an LLM guardrail for semantic policy; use a custom or external guardrail when policy needs an application service. A guardrail can retry, fail closed, provide a custom repair, or pause for durable human review. Put the strongest guardrail directly before a consequential tool call. - ``` - "conductor-agent-" + workflowInstanceId + ":" + referenceTaskName + ":" + iteration - ``` +Before promotion, evaluate the recorded agent behavior—not only its final text. The Python SDK's evaluation harness can assert tool selection and arguments, handoffs, guardrail events, turn counts, and terminal state, then use an optional LLM judge for qualitative criteria. See [Agent Guardrails](agent-guardrails.md) and [Agent Evals](agent-evals.md) for the runtime policy and CI patterns. - It is built from retry-stable identity — **not** `taskId`, which changes per retry attempt. -- **Absolute deadline.** Anchored once at start; the task fails terminally after `maxDurationSeconds` (default 86400) if the run never reaches a terminal state. The abandoned child execution is also given a best-effort `terminateWorkflow` call so it doesn't keep running orphaned. -- **Poll-failure cap.** Consecutive transient poll failures are counted and reset to 0 on any success; the task fails terminally at `maxPollFailures` (default 30), with the same best-effort child termination. +## Workflow-integration recipes -`maxDurationSeconds`/`maxPollFailures` are this branch's own liveness guards, independent of the Conductor engine's standard task-level timeout (`taskDefinition.timeoutSeconds`/`responseTimeoutSeconds`/`timeoutPolicy`, set inline on the `AGENT` `WorkflowTask` — not as an `inputParameters` field). Note: as of this writing, the engine does not invoke a system task's `cancel()` hook when the task's *own* `TaskDef` timeout fires (it only does so for still-running sibling tasks once the whole workflow becomes terminal) — a general gap that also affects `SUB_WORKFLOW`. Until that's addressed at the engine level, `maxDurationSeconds` is the reliable way to guarantee the child agent execution is cleaned up. +These repository examples deliberately contain only the stable workflow contract.

A crashed pod replays every LLM call from the beginning — burning tokens and money. A human approval that took three days is lost because a deploy bounced the server. A multi-hour research pipeline fails at step 47 and starts over from step 1. +Durable-agent guidance now lives in [Production Agent Architecture](production-agent-architecture.md), including persistence, approvals, recovery, compensation, observability, and multi-agent composition. -Conductor eliminates all of this. Every step of a durable agent workflow is persisted to storage as it completes. If the process dies, the agent resumes from the last completed step — not from the beginning. - - -## What gets persisted - -- The **workflow definition snapshot** (immutable for this execution). -- Each **LLM call**: input prompt, model response, token usage, latency. -- Each **tool call**: input, output, status, retry count. -- Each **wait state**: when it started, what it's waiting for, the resume payload when it arrives. -- Each **human decision**: who approved, when, with what data. -- The **loop state**: iteration count, intermediate results, exit condition evaluation. - -No LLM calls are repeated unless a task explicitly failed and needs retry. A human approval that completed on Tuesday is still there on Wednesday, even if the cluster was replaced overnight. This is what makes Conductor-based agents production-ready. - - -## JSON is AI-native - -LLMs natively produce JSON. Conductor natively executes JSON. This means an agent can generate its own execution plan as a workflow definition and Conductor will execute it immediately — no compilation, no deployment, no code generation step. - -``` -LLM generates plan → JSON workflow definition → Conductor executes it -``` - -This is not a workaround. It is the intended design, and it makes Conductor uniquely suited to agent orchestration: - -**Runtime generation.** An LLM or planner emits a workflow definition as JSON, your code passes it to the [StartWorkflowRequest API](../../documentation/api/startworkflow.md), and Conductor validates, persists, and executes it immediately — without pre-registration. The workflow itself becomes a first-class output of the agent's planning step. - -**Inspectability.** Every agent run is a JSON document you can query, diff, and audit. You can see exactly what the LLM decided, what tools were called, what the human approved, and in what order. No opaque framework state — just data. - -**Versioning.** Workflow definitions are versioned. Run multiple agent versions concurrently, A/B test different tool configurations, and roll back without affecting running executions. - -**SDK/UI/API parity.** The same workflow can be defined via JSON file, SDK code, API call, or the Conductor UI. All paths produce the same stored JSON definition. An agent that generates workflows programmatically and a human who designs them in the UI are using the same runtime. - - -## Error handling and compensation - -Agents don't just read data — they take actions. They send emails, create tickets, charge cards, update databases. When a step fails after earlier steps have already produced side effects, you need compensation: the ability to undo or mitigate what was already done. - -Conductor provides this through the `failureWorkflow` field and the saga compensation pattern: - -```json -{ - "name": "booking_agent", - "failureWorkflow": "booking_agent_compensation", - "tasks": [ - { "name": "reserve_flight", "type": "HTTP", "taskReferenceName": "flight" }, - { "name": "reserve_hotel", "type": "HTTP", "taskReferenceName": "hotel" }, - { "name": "charge_payment", "type": "HTTP", "taskReferenceName": "payment" } - ] -} -``` - -If `charge_payment` fails, the `booking_agent_compensation` workflow runs automatically. It receives the full execution state — including the outputs of `reserve_flight` and `reserve_hotel` — so it can cancel the flight, release the hotel reservation, and notify the user. - -This is not error handling you bolt on later. It is built into the execution model: - -- **`failureWorkflow`** runs a separate workflow on failure, with full access to the failed execution's state. -- **Retry policies** on individual tasks (fixed, exponential backoff, linear) with configurable limits. -- **Timeout policies** that fail or alert when an LLM call or tool takes too long. -- **`TERMINATE` task** to end execution early with a specific status and output when the agent detects an unrecoverable condition. - -Most AI frameworks have no concept of compensation. If your LangChain agent sends an email in step 3 and crashes in step 5, the email is already sent and there is no built-in mechanism to undo it. Conductor's failure workflows solve this. - - -## Multi-agent composition - -Real-world AI systems rarely run as a single agent. A research agent delegates to specialist sub-agents. A customer service agent escalates to a billing agent. A planning agent spawns parallel analysis agents and synthesizes their results. - -Conductor models this with `SUB_WORKFLOW` tasks inside a `FORK`/`JOIN` for parallel execution: - -```json -{ - "name": "research_coordinator", - "tasks": [ - { - "name": "plan", - "type": "LLM_CHAT_COMPLETE", - "taskReferenceName": "plan", - "inputParameters": { - "llmProvider": "anthropic", - "model": "claude-sonnet-4-20250514", - "messages": [ - { "role": "user", "message": "Break this research task into sub-tasks: ${workflow.input.topic}" } - ] - } - }, - { - "name": "fork_sub_agents", - "type": "FORK_JOIN", - "taskReferenceName": "fork", - "forkTasks": [ - [ - { - "name": "run_web_researcher", - "type": "SUB_WORKFLOW", - "taskReferenceName": "web_research", - "subWorkflowParam": { "name": "web_research_agent", "version": 1 }, - "inputParameters": { "query": "${plan.output.result.webQuery}" } - } - ], - [ - { - "name": "run_data_analyst", - "type": "SUB_WORKFLOW", - "taskReferenceName": "data_analysis", - "subWorkflowParam": { "name": "data_analysis_agent", "version": 1 }, - "inputParameters": { "dataset": "${plan.output.result.dataset}" } - } - ] - ] - }, - { - "name": "join_sub_agents", - "type": "JOIN", - "taskReferenceName": "join", - "joinOn": ["web_research", "data_analysis"] - }, - { - "name": "synthesize", - "type": "LLM_CHAT_COMPLETE", - "taskReferenceName": "synthesize", - "inputParameters": { - "llmProvider": "anthropic", - "model": "claude-sonnet-4-20250514", - "messages": [ - { "role": "user", "message": "Synthesize these findings:\n\nWeb research: ${web_research.output}\n\nData analysis: ${data_analysis.output}" } - ] - } - } - ], - "failureWorkflow": "research_coordinator_cleanup" -} -``` - -Both sub-agents run concurrently. The `JOIN` waits for both to complete before the synthesize step runs. If you don't know the number of sub-agents ahead of time, use `DYNAMIC_FORK` instead — the LLM's plan output determines how many sub-agents to spawn. - -**What you get from multi-agent composition in Conductor:** - -- **Parallel execution.** Sub-agents run concurrently via `FORK`/`JOIN` or `DYNAMIC_FORK`. The join collects all results before the next step proceeds. -- **Full observability across the agent tree.** The parent workflow shows the status of each sub-agent. You can drill into any sub-workflow to see its individual LLM calls, tool calls, and decisions. -- **Failure isolation.** A failing sub-agent does not crash the parent. The parent can catch the failure, retry with different parameters, or route to a fallback agent. -- **Failure propagation with compensation.** If a sub-agent fails and the parent should also fail, `failureWorkflow` runs compensation across the entire agent tree. -- **Independent scaling.** Each sub-agent type can have its own workers scaled independently. A CPU-heavy data analysis agent doesn't compete for resources with a lightweight web research agent. - - -## Observability - -Every agent execution in Conductor is fully observable — not through external logging you have to set up, but as a built-in property of the execution model. Because every step is persisted, the observability is automatic and complete. - -**What you can see for every agent run:** - -- **Task-by-task execution timeline.** Each task shows its status (scheduled, in progress, completed, failed), start time, end time, and duration. You see exactly where an agent is in its workflow at any moment. -- **Every LLM prompt and response.** The full input messages, model response, token usage (prompt tokens, completion tokens), and latency for each `LLM_CHAT_COMPLETE` or `LLM_TEXT_COMPLETE` call. You can inspect exactly what the agent decided and why. -- **Every tool call with input/output.** For `CALL_MCP_TOOL`, `HTTP`, and custom worker tasks: the exact arguments sent, the response received, and how many retry attempts were needed. -- **Human approval audit trail.** For `HUMAN` tasks: when the task was created, who completed it, when they completed it, and what data they provided. This is an immutable audit record. -- **Loop iteration history.** For `DO_WHILE` agent loops: the iteration count, the result of each iteration, and the exit condition evaluation. You can trace the agent's reasoning across its entire plan/act/observe cycle. -- **Sub-agent drill-down.** For `SUB_WORKFLOW` tasks: click through to the child workflow's full execution view. The parent shows the sub-agent's overall status; the child shows every step within it. -- **Retry and failure history.** Every retry attempt is recorded with its input, output, and failure reason. If a task failed three times before succeeding, all four attempts are visible. - -This observability applies to every workflow — including workflows [generated dynamically by an LLM](dynamic-workflows.md).

They make every execution comparable and guarantee that the example visibly completes four loop iterations. The fourth pass is adaptive: the model can select only one or two entries from the fixed deep-dive set, and a JQ guard validates, deduplicates, and caps those inputs before `FORK_JOIN_DYNAMIC` creates `CALL_MCP_TOOL` tasks. + +That distinction matters. The agent selects approved paths and fan-out at runtime; it does not mutate the running workflow snapshot or invent a new capability. PR text, comments, and diffs are treated as untrusted evidence in every LLM prompt, never as instructions. + +## Safety and durability model + +| Concern | Guardrail in the example | +|---|---| +| Missing capability | Tool discovery verifies both required GitHub MCP tools before the loop starts. | +| Runaway agent | `DO_WHILE` is fixed at four iterations; deep dive fan-out is capped at two calls; the workflow has a 20-minute timeout. | +| Oversized context | Each MCP result is retained durably but reduced to a bounded evidence excerpt before an LLM evaluates it. | +| Malformed model output | Invalid JSON fails and retries at the LLM task; a parseable but invalid assessment becomes an explicit unknown result through the JQ contract guard. An invalid final draft fail-closes before approval. | +| External write | A `HUMAN` task must return `approved: true` before `add_issue_comment` can run. | +| Duplicate comment | The generated comment includes a workflow-ID marker; the graph checks existing PR comments for that marker before publishing. | +| Ambiguous write failure | Comment creation has no idempotency key, so its retry count is zero. Reconcile an ambiguous failure by searching for the marker; do not blindly retry the write. | +| Cancellation | Terminating before the approved write produces no comment. Cancellation during an in-flight write also requires marker-based reconciliation. | + +The reviewer intentionally keeps all four iterations. Do not set `keepLastN` here: `keepLastN` removes older loop output and task history, which is the wrong trade-off for a short audit trail. For long-running loops, use it only when that loss of history is acceptable. -See the full set of examples in the [`ai/examples/`](https://github.com/conductor-oss/conductor/tree/main/ai/examples) directory. +## Recovery and operations +- Infrastructure recovery and ordinary task-scoped retries preserve completed upstream tasks.

Instead of following a fixed sequence of steps, it works in turns: the model reads the goal and the context so far, then proposes the next action. That action might be a tool call, a question for a person, or a final answer. The result of each action becomes context for the next turn, and the loop continues until the goal is met. + +
+ + The Conductor agent turn loop + An LLM proposes the next action. Conductor validates the proposal, persists state, and schedules the work. Workers, MCP tools, remote agents, and people execute it. Results are saved and start the next turn. + + + + + + + LLM decides the next step + proposes a tool call, a question, or an answer + + + Conductor + validates the proposal · applies approvals + persists state · schedules the work + + + Workers + your code + + MCP tools + tools + data + + Remote agents + A2A protocol + + People + review + input + + results are saved and start the next turn + +
+ +In Conductor, that loop runs as a durable workflow. The model's proposal is data, not a command. Conductor validates it, applies any required approvals, and only then schedules the work. The work itself runs as ordinary tasks, using the same building blocks a workflow already has: your workers, MCP tools, remote agents, and people. Because every result is persisted before the next turn starts, a crash, deploy, or long wait never loses the agent's progress. + +## Three ways to build + +The paths are complementary. A production workflow can use native AI tasks, invoke a compiled Conductor Agent, and delegate specialist work to a remote A2A agent in the same durable graph. + +

Conductor manages the handoff without compiling that agent locally. + +
+ +## Operating principles + +Adaptive behavior stays manageable when the execution contract is explicit. These principles apply across all three authoring paths. + +
+
+ 01 + Model output is a proposal + Plans and tool arguments must pass schema validation, policy, guardrails, and approval before they become executable work. +

+ 02 + State belongs in the workflow + Progress, waits, decisions, and results live in durable execution state—not only in the memory of an agent process. +
+
+ 03 + Side effects cross task boundaries + Workers and system tasks perform approved actions through bounded, observable interfaces with defined retries and timeouts. +

An open-source durable execution platform for workflow orchestration, adaptive agents, AI systems, polyglot workers, and self-hosted deployment." --- # Why Conductor -Conductor is an open source workflow engine built for workflow orchestration at scale. It orchestrates distributed workflows across services, languages, and infrastructure — tracking every state transition, retrying failures automatically, and giving you full visibility into what happened and why. Whether you need microservice orchestration, AI agent orchestration, or workflow automation, Conductor provides a self-hosted, code-first platform with no vendor lock-in. +Conductor is an engine that orchestrates workflows across services and languages. It records every state transition, retries failures automatically, and keeps a full history of what happened and why. ## The problem -Distributed systems fail. Services crash, networks drop, deployments roll mid-flight. Without a workflow orchestration platform, you end up writing retry logic, state tracking, timeout handling, and compensation flows into every service. That logic is scattered, inconsistent, and invisible. +Every distributed process has to survive failure. Without coordination, each service carries its own retry, timeout, and recovery logic. That logic gets duplicated everywhere and owned by no one. -**Choreography** (peer-to-peer events) makes this worse at scale: +One common proposed solution is **choreography**, where services react to each other's events with no central coordinator. This keeps services decoupled on paper, but the logic of the overall business process is not visible. The flow exists only as an implied chain of event contracts, so changing one service can break consumers it cannot see. Observing the process is also hard. For example debugging a failure means correlating logs across all of the services. -- Business processes are implicit — embedded across dozens of services with no single view of the flow. -- Tight coupling through assumed message contracts makes changes risky. -- "How far along is order #12345?" requires querying every service in the chain. -- Debugging a failure means correlating logs across services, queues, and time. - -**Orchestration** centralizes the flow definition while keeping execution distributed. Conductor is the orchestrator — your workers stay stateless and independent. - -## What Conductor gives you - -### Durable execution -Conductor is a durable execution engine — every workflow execution is persisted. If a task fails, Conductor retries it with configurable backoff including exponential backoff. If a worker crashes, the task is rescheduled. If the server restarts, execution resumes exactly where it left off. Your code doesn't need to handle retry logic — Conductor provides it out of the box. This same durable execution guarantee powers durable agents that survive infrastructure failures. - -### Language-agnostic workers -Write workers in Python, Java, Go, JavaScript, C#, or Clojure. Each task in a workflow can use a different language — pick the best tool for each job. Workers communicate with Conductor via REST or gRPC and can run anywhere: containers, VMs, serverless, or your laptop. - -### Built-in system tasks -HTTP calls, inline JavaScript execution, JSON transforms, event publishing, wait timers, and human approval gates — all available without writing a single worker. See [System Tasks](../../documentation/configuration/workflowdef/systemtasks/index.md). - -### Flow control operators -Fork/join for parallelism, switch for conditional branching, do-while for loops, sub-workflows for composition, and dynamic tasks resolved at runtime. See [Operators](../../documentation/configuration/workflowdef/operators/index.md). - -### AI agent orchestration and LLM orchestration -Conductor provides LLM orchestration and AI agent orchestration as native system tasks — no external frameworks required. Supported providers include Anthropic (Claude), OpenAI (GPT), Azure OpenAI, Google Gemini, AWS Bedrock, Mistral, Cohere, HuggingFace, Ollama, Perplexity, Grok, and StabilityAI — 14+ providers available out of the box for chat completion, text completion, and embedding generation. - -MCP (Model Context Protocol) integration is built in: use `LIST_MCP_TOOLS` to discover available tools and `CALL_MCP_TOOL` to invoke them — enabling function calling and tool use within workflows with full retry and state tracking. - -For RAG pipelines, Conductor supports three vector databases natively — Pinecone, pgvector, and MongoDB Atlas — so you can index embeddings, run similarity search, and feed results to an LLM in a single workflow definition. - -Content generation tasks cover image, audio, video, and PDF creation using AI models. Every AI task runs with the same durability guarantees as any other Conductor task: automatic retries, timeout handling, and a complete audit trail. - -### Event-driven workflows -Publish to and consume from Kafka, NATS, AMQP (RabbitMQ), and SQS. Trigger workflows from external events or emit events from within workflows. See [Event Bus Orchestration](../how-tos/event-bus.md). - -### Full operational control -Pause, resume, restart, retry, and terminate any workflow execution. Search and filter executions by status, time, correlation ID, or custom tags. Every task has a complete audit trail — inputs, outputs, timestamps, retry history, and worker identity. - -### Horizontal scaling -Conductor scales horizontally to millions of concurrent workflow executions. Workers scale independently — add more instances and Conductor distributes tasks automatically. Rate limits and concurrency caps prevent overload. This workflow engine scalability makes Conductor suitable for production deployments at any scale. - -## When to use Conductor - -| Use case | Example | -| :--- | :--- | -| **Microservice orchestration** | Order processing: payment → inventory → shipping → notification | -| **Workflow automation** | Automate business processes with durable execution, retries, and full observability | -| **Durable agents** | Multi-step LLM chains with function calling, tool use, RAG, and human-in-the-loop — durable agents that survive crashes | -| **Long-running workflows** | Insurance claims, loan approvals, onboarding flows spanning days or weeks — async workflows that survive deploys | -| **Event-driven automation** | React to Kafka events, trigger workflows, publish results back | -| **Batch processing** | Fan-out work across thousands of parallel workers with dynamic fork | -| **Saga pattern** | Distributed transactions with compensation on failure | -| **RAG applications** | Build retrieval-augmented generation pipelines with vector search, embedding generation, and LLM completion as workflow tasks | -| **Content generation pipelines** | Generate images, audio, video, and PDFs using AI models orchestrated as durable workflows | - -## What sets Conductor apart - -No other open source workflow engine matches this combination: - -- **14+ native LLM providers as system tasks** — Anthropic, OpenAI, Azure OpenAI, Gemini, Bedrock, Mistral, Cohere, HuggingFace, Ollama, Perplexity, Grok, StabilityAI, and more.

Design patterns are complete, runnable workflow definitions for common orchestration problems. Each page takes one problem, such as parallel fan-out, sagas, timers, or human approval, and gives you a working definition to register, run, and adapt to your own tasks. This section covers workflow patterns. Agentic patterns and agent recipes live in AI Cookbook.

Conductor supports advanced patterns including nested loops, dynamic branching, sub-workflows, and workflows with thousands of tasks. -## How does Conductor compare to other workflow engines? +## What does Conductor provide? -Conductor combines durable execution, 14+ native LLM providers, JSON-native workflow definitions, 7+ language SDKs, and battle-tested scale (Netflix, Tesla, LinkedIn, JP Morgan). It's the only open source workflow engine with native AI/LLM task types, MCP integration, and built-in vector database support. +Conductor combines durable workflow execution with built-in system tasks, JSON-native workflow definitions, polyglot workers, and native AI and MCP capabilities. Use it to coordinate distributed services, framework-authored agents, and adaptive runtime paths while retaining an inspectable execution record. ### Isn't JSON too limited for complex workflows? -No — JSON makes workflows *more* capable, not less. A JSON workflow definition is pure orchestration: it describes what runs, in what order, with what inputs. It cannot open connections, mutate state, or produce side effects. This means every execution is deterministic by construction — given the same inputs, the same task graph executes every time. That is why replay, restart, and retry work unconditionally. +No. A JSON definition expresses orchestration data: task order, inputs, outputs, operators, and policy. Put side effects in built-in tasks or workers, where they can be observed and retried. The graph remains machine-readable and versioned, while the worker remains ordinary code. -Code-based workflow engines embed orchestration logic alongside business logic, which means your workflow code can introduce non-determinism (system clocks, random values, uncontrolled I/O). These engines must impose restrictions on what your code is allowed to do — and bugs from violating those restrictions are subtle and hard to debug. - -Conductor's dynamic primitives — [DYNAMIC tasks](../documentation/configuration/workflowdef/operators/dynamic-task.md), [DYNAMIC_FORK](../documentation/configuration/workflowdef/operators/dynamic-fork-task.md), and [dynamic sub-workflows](../documentation/configuration/workflowdef/operators/sub-workflow-task.md) — provide more runtime flexibility than code-based definitions. An LLM can generate a complete workflow definition as JSON and Conductor executes it immediately, with full durability and observability. No code generation, no compilation, no deployment. See [JSON + Code Native](../architecture/json-native.md) for the full picture. - -### How is Conductor different from Temporal? - -Both are durable execution engines, but with fundamentally different approaches. Conductor's JSON-native definitions separate orchestration from implementation, making workflows deterministic by construction — no side-effect restrictions to remember, no non-determinism bugs to debug. Temporal embeds orchestration in code, which requires developers to avoid non-deterministic operations (system clocks, random values, uncontrolled I/O) or risk subtle replay failures. - -Conductor is fully open source (Apache 2.0) with no proprietary server components. It provides native LLM orchestration for 14+ providers, MCP tool calling, and vector database support out of the box — capabilities Temporal does not offer. Conductor's JSON definitions can be generated and modified at runtime by LLMs or APIs without a compile/deploy cycle. - -### How is Conductor different from AWS Step Functions? - -Step Functions is a proprietary, cloud-locked service. Conductor is an open source, self-hosted workflow engine you can run on any infrastructure. Conductor supports 7+ language SDKs, 5 persistence backends, and provides native AI agent orchestration — none of which Step Functions offers. If you need an open source Step Functions alternative with no cloud lock-in, Conductor is a strong fit. - -### How is Conductor different from Airflow? - -Airflow is a DAG-based batch scheduler designed for data pipelines. Conductor is a real-time workflow orchestration engine designed for microservice orchestration, event-driven workflows, and AI agent orchestration. Conductor provides durable execution with sub-second task scheduling, while Airflow is optimized for scheduled batch jobs.

+

An event handler is a registered rule that consumes messages from a broker and turns them into workflow actions. When a message arrives on the queue the handler watches, the handler evaluates its condition against the payload and can start a new workflow, or complete or fail one specific task. Handlers are how outside systems drive workflows without calling the Conductor API themselves.

Event-driven orchestration connects workflows to the messages around them. A workflow can publish to a broker, an incoming message or webhook can start or advance workflows, and a signal can resume one specific execution that is waiting. Each page in this section covers one of those directions, and the table below routes you to the right one.

A webhook is an HTTP endpoint that an external service calls when something happens on its side. Conductor verifies the caller's signature first, records the delivery durably, and then either starts a new workflow or resumes one waiting on WAIT_FOR_WEBHOOK. This page covers configuring the endpoint, verification, and both delivery modes.

+

A workflow can send a message to the outside world with the EVENT task. The task takes resolved workflow data, adds durable metadata, and publishes the message to a configured provider such as Kafka or SQS. The publish is a normal step in the execution, so it is recorded and retried like any other task. Use KAFKA_PUBLISH only when you need Kafka-specific producer controls.

The server reads the highest version and saves one past it, with nothing between the two steps, so both writers can read the same maximum, land on the same version and leave only the later one stored.

Two kinds are not covered: an asynchronous system task such as `HTTP` or `SUB_WORKFLOW`, and a synchronous one that completes during scheduling instead. For those, an `outputSchema` on the task definition is stored and never enforced. That and the externalized output above pass quietly, and so does the unresolvable reference described below; the non-`JSON` and typeless schemas below are the ones that fail loudly instead. Every system task's *input* is validated at scheduling like any other task's, and workflow input and workflow output are unaffected. + +**A schema that is not `JSON` is refused, not skipped.** An `AVRO` or `PROTOBUF` schema is accepted at registration and returned unchanged, but this server has no validator for it — so rather than let the payload through unchecked, it fails the execution and says why. A definition that both attaches one and opts into enforcement will start failing when you turn enforcement on. + +**A schema carrying no `type`, or only an `externalRef`, is refused too.** Neither names a document this server can check against — nothing dereferences `externalRef` — so both fail the execution and say so. + +**A reference the registry does not hold stops enforcing, quietly.** A schema attached by name and version is looked up in the [Schema Registry](schema-registry.md); if nothing is registered under that name and version there is no document to validate against, so the payload goes through unchecked rather than failing. The miss increments the `schema_registry_miss` counter, tagged with the schema name — that counter is the only signal, so watch it if you rely on enforcement. A registered document the validator cannot read or use behaves the same way and is logged. The common cause is a missing `$schema` line: without it the validator cannot tell which JSON Schema version to apply, so a document that otherwise looks correct enforces nothing. Both are errors in the definition rather than in the payload, which is why neither is charged to the caller; the cost is that a reference pointing at nothing enforces nothing. + +## Writing schemas that age well + +`additionalProperties: false` deserves a moment's thought. It turns an unexpected field into a hard failure — right for a contract you own end to end, a nuisance for one where callers legitimately pass extra context. Leave it out unless you mean it. + +Adding a field to `required` is a breaking change for every existing caller. Because a running execution keeps the definition version it started with, the safe path is the same as any other definition change: register a new version rather than editing the current one.

Durable execution by default

-

Workflow state is persisted at every step. Survive server restarts, worker crashes, and network failures. Durable execution with at-least-once task delivery, configurable retries, timeouts, and compensation flows. Build durable agents that never lose progress.

JSON superpower
-

JSON native — deterministic by default

-

JSON definitions separate orchestration from implementation — no side effects, no hidden state, every run is deterministic. Generate workflows at runtime with LLMs, modify per-execution, and use dynamic forks, dynamic tasks, and dynamic sub-workflows for more flexibility than code-based engines. Code via SDKs when you need it.

Primitives
-

Replay, Restart, Pause, Resume

-

Pause workflows on time, external signals, webhooks, or human approval. Resume safely after minutes, hours, or days. Replay any workflow from the beginning, from a specific task, or retry just the failed step — even months later. Full execution history is always preserved.

Is Conductor open source? @@ -194,15 +176,15 @@ description: Conductor is an open source workflow engine and durable execution p
Can Conductor scale to handle my workload? -

Conductor was built at Netflix to handle massive scale and has been battle-tested in production environments processing millions of workflows. It scales horizontally to meet virtually any demand.

+

Conductor servers and workers scale independently. Use task domains, concurrency limits, persistence configuration, and metrics to match throughput and isolation to your environment.

Does Conductor support durable execution? -

Yes. Conductor pioneered durable execution patterns, ensuring workflows and durable agents complete reliably even in the face of infrastructure failures, process crashes, or network issues.

+

Yes. Conductor persists workflow and task state, supports recovery after worker and infrastructure failure, and exposes retries, timeouts, pause, resume, and termination controls.

Can I replay a workflow after it completes or fails? -

Yes. Conductor preserves full execution history indefinitely. You can restart from the beginning, rerun from any specific task, or retry just the failed step — even months later. Use the API (/restart, /rerun, /retry) or the UI.

+

Conductor supports restart, rerun, and retry controls. Execution-history retention depends on configuration, and keepLastN intentionally removes older loop iterations.

Are workflows always asynchronous? @@ -214,7 +196,7 @@ description: Conductor is an open source workflow engine and durable execution p
Isn't JSON too limited for complex workflows? -

The opposite. JSON separates orchestration from implementation, making every workflow deterministic by construction — no side effects, no hidden state. Dynamic forks, dynamic tasks, and dynamic sub-workflows let you build workflows that are more flexible than code-based engines. JSON is also AI-native: LLMs can generate and modify workflow definitions at runtime without a compile/deploy cycle. Code-based engines require redeployment for every change.

+

JSON keeps orchestration as machine-readable data while workers and built-in tasks perform business logic and side effects. Use validated runtime definitions, dynamic tasks, and dynamic forks when the path is selected at runtime.

Is Conductor a low-code/no-code platform? @@ -234,52 +216,13 @@ description: Conductor is an open source workflow engine and durable execution p
Can Conductor orchestrate AI agents and LLMs? -

Yes. Conductor provides AI agent orchestration and LLM orchestration as native capabilities. 14+ LLM providers (Anthropic, OpenAI, Azure OpenAI, Google Gemini, AWS Bedrock, Mistral, Cohere, HuggingFace, Ollama, and more), MCP tool calling and function calling (LIST_MCP_TOOLS, CALL_MCP_TOOL), vector database integration (Pinecone, pgvector, MongoDB Atlas) for RAG, and content generation (image, audio, video, PDF). All with the same durability guarantees as any other workflow task.

+

Yes. Conductor provides native LLM tasks, MCP tool discovery and calls, human approval, and vector workflows for RAG. See the maintained Agents & AI documentation for provider and capability details.

- How does Conductor compare to other workflow engines? -

Conductor is the only open source workflow engine with native LLM task types for 14+ providers, built-in MCP integration, and vector database support. Combined with durable execution, 7+ language SDKs (Java, Python, Go, JavaScript, C#, Ruby, Rust), 6 message brokers, 5 persistence backends, and battle-tested scale at Netflix, Tesla, LinkedIn, and JP Morgan, Conductor provides the most complete workflow orchestration platform available. Unlike Temporal, Step Functions, or Airflow, Conductor is fully self-hosted, supports both code-first and JSON workflow definitions, and provides native AI agent orchestration out of the box.

+ What does Conductor provide for adaptive agents? +

Conductor combines native AI and MCP tasks with durable loops, branches, fan-out, approval, retry, cancellation, and an inspectable execution history. Start with the governed adaptive graph.

A **workflow definition** declares which tasks run, in what order, and how data passes between them. When you start a workflow, Conductor creates a **workflow execution**, which is a single run of that blueprint with its own ID, input, and history. Because the two are separate, editing a definition never rewrites the history of an execution that already ran. In practice, developers evolve definitions through versions, while operators inspect and recover executions. + +Every workflow moves through the same lifecycle: + +```mermaid +flowchart LR + define[Build a definition] --> register[Register a version] + register --> trigger[Start or trigger] + trigger --> execute[Durable execution] + execute --> observe[Inspect and operate] + observe --> evolve[Version and roll out] + evolve --> register +``` + +An execution is durable because Conductor saves progress after every task. That is why work can span services, wait on people or timers, and pick up where it left off after a restart. Since Conductor hands work from one task to the next, each task must spell out its own contract: where its inputs come from and what happens when it fails. Worker tasks add one more requirement. If no worker is polling for the task, the workflow simply waits and does not advance. + +Day-to-day work with workflows typically falls into one of the following four activities. + +

Schedules always create executions. Events can create executions or complete/fail an identified task. Workflow composition expresses a known dependency directly. Signals resume work that already exists. + +During **Operate**, configure task retries and all relevant timeouts, define idempotent worker behavior, carry correlation data, monitor queues and execution state, and rehearse recovery.

Conductor persists state at every step, so a long-running workflow or async workflow picks up exactly where it left off — even after days or weeks. +- **JSON-native definitions** — Every workflow is a JSON workflow definition you can store in version control, diff across releases, and generate programmatically. No compiled DSL or proprietary format required. +- **Dynamic workflows** — Workflows can be created and modified at runtime as code-first or JSON definitions, enabling use cases where the task graph is not known ahead of time (for example, when the number of parallel branches depends on an API response). +- **Versioned** — Each workflow definition carries an explicit version number so you can roll out changes incrementally and run multiple versions side by side. +- **Language-agnostic** — Workers that execute tasks can be written in any language — Java, Python, Go, JavaScript, C#, or Clojure — and deployed anywhere. The workflow definition itself is decoupled from implementation. + + +## Workflow definition + +The workflow definition describes the flow and behavior of your business logic. Think of it as a blueprint specifying how it should execute at runtime until it reaches a terminal state. The workflow definition includes: + +- The workflow's input/output keys. +- A collection of [task configurations](tasks.md#task-configuration) that specify the task conditions, sequence, and data flow until the workflow is completed. +- The workflow's runtime behavior, such as the timeout policy and compensation flow. + + +### Example JSON workflow definition + +Below is a realistic three-task workflow that fetches data from an API, transforms it with an inline script, and then delegates the result to a worker task for further processing. + +```json +{ + "name": "process_order", + "description": "Fetch order details, enrich them, and hand off to fulfillment", + "version": 1, + "schemaVersion": 2, + "ownerEmail": "team-platform@example.com", + "timeoutPolicy": "ALERT_ONLY", + "timeoutSeconds": 3600, + "restartable": true, + "failureWorkflow": "handle_order_failure", + "inputParameters": ["orderId"], + "outputParameters": { + "enrichedOrder": "${enrich_order.output.result}", + "fulfillmentStatus": "${fulfill_order.output.status}" + }, + "tasks": [ + { + "name": "fetch_order", + "taskReferenceName": "fetch_order", + "type": "HTTP", + "inputParameters": { + "http_request": { + "uri": "https://api.example.com/orders/${workflow.input.orderId}", + "method": "GET", + "connectionTimeOut": 5000, + "readTimeOut": 5000 + } + } + }, + { + "name": "enrich_order", + "taskReferenceName": "enrich_order", + "type": "INLINE", + "inputParameters": { + "order": "${fetch_order.output.response.body}", + "evaluatorType": "graaljs", + "expression": "(function() { var o = $.order; o.region = o.country === 'US' ?

Used when starting executions. | +| **version** | `integer` | The version of the workflow definition. Allows multiple versions to coexist. | +| **tasks** | `array[object]` | An ordered list of [task configurations](tasks.md#task-configuration) that define the workflow's execution graph. | +| **inputParameters** | `array[string]` | List of input keys the workflow expects when triggered. | +| **outputParameters** | `object` | Mapping of output keys to expressions that extract values from task outputs. | +| **failureWorkflow** | `string` | Name of a workflow to trigger when this workflow transitions to FAILED. Useful for compensation or alerting. | +| **timeoutPolicy** | `string` | Policy to apply when the workflow exceeds `timeoutSeconds`. Supported values: `TIME_OUT_WF` (fail the workflow) or `ALERT_ONLY` (mark timed out but keep running). | +| **timeoutSeconds** | `integer` | Maximum time (in seconds) the workflow is allowed to run before the timeout policy is applied.

Defaults to `true`. | +| **ownerEmail** | `string` | Email address of the workflow owner. Used for notifications and audit tracking. | +| **schemaVersion** | `integer` | Schema version of the workflow definition format. Current version is `2`. | + + +## Workflow execution + +A workflow execution is the execution instance of a workflow definition. + +Whenever a workflow definition is invoked with a given input, a new workflow execution with a unique ID is created. The workflow is governed by a defined state (like RUNNING or COMPLETED), which makes it intuitive to track the workflow. + + +### Workflow execution states + +Each workflow execution transitions through a set of well-defined states: + +| State | Description | +|---|---| +| **RUNNING** | The workflow is actively executing tasks. | +| **COMPLETED** | All tasks finished successfully and the workflow reached its terminal state. | +| **FAILED** | One or more tasks failed and the workflow could not recover. If a `failureWorkflow` is configured, it will be triggered. | +| **TIMED_OUT** | The workflow exceeded its configured `timeoutSeconds` and the `timeoutPolicy` was set to `TIME_OUT_WF`. | +| **TERMINATED** | The workflow was explicitly stopped by an API call or system action. | +| **PAUSED** | The workflow has been paused and will not schedule new tasks until resumed. | + +The following diagram illustrates how a workflow transitions between states: + +```mermaid +stateDiagram-v2 + [*] --> RUNNING + RUNNING --> COMPLETED : all tasks succeed + RUNNING --> FAILED : task failure (unrecoverable) + RUNNING --> TIMED_OUT : timeout exceeded + RUNNING --> TERMINATED : API termination + RUNNING --> PAUSED : pause requested + PAUSED --> RUNNING : resume requested + PAUSED --> TERMINATED : API termination + FAILED --> RUNNING : retry + TIMED_OUT --> RUNNING : retry + TERMINATED --> RUNNING : restart (if restartable) + COMPLETED --> [*] + FAILED --> [*] + TIMED_OUT --> [*] + TERMINATED --> [*] +``` + + +## Next steps + +- [Tasks](tasks.md) — Learn about the building blocks that make up a workflow, including system tasks, worker tasks, and operators. +- [Workers](workers.md) — Understand how to implement task workers in any programming language. +- [Handling errors](../how-tos/Workflows/handling-errors.md) — Configure retries, failure workflows, and compensation strategies. + + + +# Creating / Updating Task Definitions + +A [task definition](../../../documentation/configuration/taskdef.md) specifies a task's general implementation details: + +- Timeout policy +- Retry logic +- Rate limit and execution limit +- Input/output keys +- Input template + +This definition applies to all instances of the task across workflows. + +You can create task definitions using the Conductor UI, CLI, or APIs for the following scenarios: + +- **Worker tasks**: all worker tasks (`SIMPLE`) must be registered to the Conductor server as a task definition before they can execute in a workflow. +- **System tasks**: system tasks don't require a task definition, but you can create one with the same name to customize retry, timeout, and rate limit behavior. + +## Using Conductor UI + +With the UI, you can create or update task definitions visually. + +### Creating task definitions + +**To create a task definition:** + +1.

In this guide, familiarise yourself with the tasks available in Conductor OSS and the differences between each of them. + +## Built-in tasks + +Built-in tasks allow you to easily run common tasks on the Conductor server without needing to build and deploy your own task workers. Here is an introduction of the built-in tasks available in Conductor: + +* **[System tasks](../../../documentation/configuration/workflowdef/systemtasks/index.md)** common tasks that allow you to get started quickly without needing custom workers. +* **[Operators](../../../documentation/configuration/workflowdef/operators/index.md)** enable you to declaratively design the workflow's control flow and logic with minimal code required. + +### System tasks + +Here are the system tasks available in Conductor OSS for common use: + +| System Task | Description | +| :-------------------- | :----------------------------------- | +| [Event](../../../documentation/configuration/workflowdef/systemtasks/event-task.md) | Publish events to an external eventing system (AMQP, SQS, Kafka, and so on). | +| [HTTP](../../../documentation/configuration/workflowdef/systemtasks/http-task.md) | Call an API or HTTP endpoint. | +| [Human](../../../documentation/configuration/workflowdef/systemtasks/human-task.md) | Wait for an external signal. | +| [Inline](../../../documentation/configuration/workflowdef/systemtasks/inline-task.md) | Execute lightweight JavaScript code inline. | +| [No Op](../../../documentation/configuration/workflowdef/systemtasks/noop-task.md) | Do nothing. | +| [JSON JQ Transform](../../../documentation/configuration/workflowdef/systemtasks/json-jq-transform-task.md) | Clean or transform JSON data using jq. | +| [Kafka Publish](../../../documentation/configuration/workflowdef/systemtasks/kafka-publish-task.md) | Publish messages to Kafka. | +| [Wait](../../../documentation/configuration/workflowdef/systemtasks/wait-task.md) | Wait until a set time or duration has passed. | + + +### Operators + +Here are the operators available in Conductor OSS for managing the flow of execution: + +| Operator | Description | +| -------------------------- | ----------------------------------------- | +| [Do While](../../../documentation/configuration/workflowdef/operators/do-while-task.md) | Execute tasks repeatedly, like a _do…while…_ statement. | +| [Dynamic](../../../documentation/configuration/workflowdef/operators/dynamic-task.md) | Execute a task dynamically, like a function pointer. | +| [Dynamic Fork](../../../documentation/configuration/workflowdef/operators/dynamic-fork-task.md) | Execute a dynamic number of tasks in parallel. | +| [Fork](../../../documentation/configuration/workflowdef/operators/fork-task.md) | Execute a static number of tasks in parallel. | +| [Join](../../../documentation/configuration/workflowdef/operators/join-task.md) | Join the forks after a Fork or Dynamic Fork before proceeding to the next task. | +| [Set Variable](../../../documentation/configuration/workflowdef/operators/set-variable-task.md) | Create or update workflow variables. | +| [Start Workflow](../../../documentation/configuration/workflowdef/operators/start-workflow-task.md) | Asynchronously start another workflow, like an entry point. | +| [Sub Workflow](../../../documentation/configuration/workflowdef/operators/sub-workflow-task.md) | Synchronously start another workflow, like a subroutine. | +| [Switch](../../../documentation/configuration/workflowdef/operators/switch-task.md) | Execute tasks conditionally, like an _if…else…_ statement. | +| [Terminate](../../../documentation/configuration/workflowdef/operators/terminate-task.md) | Terminate the current workflow, like a _return_ statement. | + +## Custom tasks + +If you need to implement custom logic beyond the scope of Conductor's system tasks, you can use Worker (`SIMPLE`) tasks instead. Unlike a built-in task, a Worker task requires setting up a worker outside the Conductor environment that polls for and executes the task. + +## Task comparison + +To help you decide on which tasks to use, here is a detailed comparison of similar tasks available in Conductor. + +### Inline vs Worker tasks + +The [Inline task](../../../documentation/configuration/workflowdef/systemtasks/inline-task.md) is used to execute custom JavaScript code directly within the workflow. It’s ideal for lightweight operations like **simple data transformations, conditional checks, or small calculations**. Because the code executes within the Conductor JVM, Inline tasks benefit from low latency, no network overhead, and easier debugging. However, it also has limitations on using other languages, custom libraries, frameworks, or stacks. + + +The Worker task is handled by external task workers that execute a custom function or service +is an external custom function or service that performs a specific task in a workflow. Written in any language of choice (Python, Java, etc), it can execute **complex business logic, custom algorithms, or long-running operations**. Worker tasks run outside the Conductor server, meaning they require additional infrastructure set-up and logging mechanisms. + +### Event vs Kafka Publish tasks + +If you only need to publish messages to a Kafka topic for external services to use, the [Kafka Publish](../../../documentation/configuration/workflowdef/systemtasks/kafka-publish-task.md) task is simpler to set up. + +In contrast, the [Event](../../../documentation/configuration/workflowdef/systemtasks/event-task.md) task supports more involved set-ups, such as using events to start a Conductor workflow, or having Conductor consume messages. It also supports a wider range of event brokers across AMQP, NATS, SQS, Kafka, and Conductor's own internal queue. + + +### Wait vs Human tasks + +The [Wait](../../../documentation/configuration/workflowdef/systemtasks/wait-task.md) task and [Human](../../../documentation/configuration/workflowdef/systemtasks/human-task.md) task both support waiting until a specific condition is met. Use the Wait task for cases when the workflow needs to wait for specific wait duration or timestamp, and use the Human task when the workflow needs to wait for an external trigger. + +### Start Workflow vs Sub Workflow tasks + +Both [Start Workflow](../../../documentation/configuration/workflowdef/operators/start-workflow-task.md) and [Sub Workflow](../../../documentation/configuration/workflowdef/operators/sub-workflow-task.md) tasks are useful for starting another workflow within a workflow. However, the Start Workflow task starts another workflow and proceeds to the next task without waiting for the started workflow to complete, while the Sub Workflow task will wait for the subworkflow to reach terminal state before proceeding to the next task. + +The Sub Workflow task provides a tighter coupling between the parent workflow and the subworkflow. This is useful for cases when you need to associate workflow progress and states, or if you need to pass the output of the subworkflow back into the parent workflow. + + +### Fork vs Dynamic Fork tasks + +Both [Fork](../../../documentation/configuration/workflowdef/operators/fork-task.md) and [Dynamic Fork](../../../documentation/configuration/workflowdef/operators/dynamic-fork-task.md) facilitate parallel execution of tasks. The Fork task executes a predetermined number of forks, while the Dynamic Fork executes a variable number of forks at runtime. + +If each fork must run a different set of tasks, it is best to use the Fork task, because Dynamic Forks can only run the same task for all its forks. + + +### Dynamic vs Switch tasks + +Both the [Switch](../../../documentation/configuration/workflowdef/operators/switch-task.md) task and the [Dynamic](../../../documentation/configuration/workflowdef/operators/dynamic-task.md) task are useful in situations when the specific task to run is determined only at runtime. Using the Switch task allows you to easily predefine and set the specific conditions for each switch case, while using the Dynamic task allows to to mark a dynamic point in the workflow without having to pre-set all the case options into the workflow definition beforehand. + +In the workflow diagram, the Dynamic task will produce a more simplified view, as it will only display the selected task. Meanwhile, the Switch task will produce a more comprehensive view that shows all possible paths that the workflow could have taken. + +Here are some scenarios for deciding between a Dynamic task and a Switch task: + + +| Scenario | Task to Use | +| -------------------------- | ----------------------------------------- | +| You have a huge number of case options or the specific case options are not yet determined. | Dynamic | +| You need a default case option. | Switch | +| Each case option involves multiple tasks. | Switch | +| The conditions for each switch case is relatively straightforward. | Switch | +| The conditions for each switch case is constantly changing, or requires more complicated logic. | Dynamic | + +If you opt for the Dynamic task, you must set up the control flow for how the task to run will be determined at runtime. For example, using a preceding task that must pass the task name into the Dynamic task. + + + +# Workers + +
+ + + + Conductor + dispatch + + + Task queue + poll + + + Worker + execute + + + Result + +
+ +A **worker** is responsible for executing a task in a workflow. Each type of worker implements the core functionality of each task, handling the logic as defined in its code. + +System task workers are managed by Conductor within its JVM, while `SIMPLE` task workers are to be implemented by yourself. These workers can be implemented in any programming language of your choice (Python, Java, JavaScript, C#, Go, and Clojure) and hosted anywhere outside the Conductor environment. + +!!! Note + Conductor provides a set of worker frameworks in its SDKs. These frameworks come with comes with features like polling threads, metrics, and server communication, making it easy to create custom workers. + +These workers communicate with the Conductor server via REST/gRPC, allowing them to poll for tasks and update the task status. Learn more in [Architecture](../architecture/index.md). + + +## How workers work + +1. **Poll** — The worker polls the Conductor server for tasks of a specific type. +2. **Execute** — The worker receives a task, executes the business logic, and produces an output. +3. **Report** — The worker reports the task result (COMPLETED or FAILED) back to the server. + +Conductor handles scheduling, retries, and state persistence. Your worker just focuses on business logic. + + +## Worker configuration + +Workers are configured through the task definition on the Conductor server. Key settings: + +| Parameter | Description | +| :--- | :--- | +| `retryCount` | Number of times Conductor retries a failed task. | +| `retryDelaySeconds` | Delay between retries. | +| `responseTimeoutSeconds` | Max time for a worker to respond after polling. | +| `timeoutSeconds` | Overall SLA for task completion. | +| `pollTimeoutSeconds` | Max time for a worker to poll before timeout. | +| `rateLimitPerFrequency` | Max task executions per frequency window. | +| `concurrentExecLimit` | Max concurrent executions across all workers. | + +See [Task Definitions](../../documentation/configuration/taskdef.md) for the full reference. + + +## Scaling task workers + +Workers can be scaled independently of the Conductor server: + +- **Horizontal scaling** — Run multiple instances of the same worker. Conductor distributes tasks across all polling workers automatically. +- **Rate limiting** — Use `rateLimitPerFrequency` to control throughput per task type. +- **Concurrency limits** — Use `concurrentExecLimit` to cap parallel executions. +- **Domain isolation** — Use [task domains](../../documentation/api/taskdomains.md) to route tasks to specific worker groups. + +See [Scaling Workers](../how-tos/Workers/scaling-workers.md) for detailed guidance. + + + +# Your First Workflow & Worker + +**Outcome:** a `greetings` workflow that queues a `greet` task and returns `Hello Conductor` from a worker. + +**Time:** about 5 minutes. + +Complete [Connect to Conductor](connect.md) first. This guide uses the SDK connection variables configured there: `CONDUCTOR_SERVER_URL`, plus `CONDUCTOR_AUTH_KEY` and `CONDUCTOR_AUTH_SECRET` when your server requires them. + +## How a worker runs + +In this quickstart you build two things: a **workflow** named `greetings` — the durable definition that Conductor executes — and a **worker** — a function in your code that performs one task inside it. + +The workflow has a single task of type `SIMPLE`, which means the work is done by your code rather than by one of Conductor's built-in tasks. Every `SIMPLE` task has a task type — here, `greet`. When a running workflow reaches that task, Conductor places it on a queue for that task type. Your worker polls the `greet` queue, runs your business logic, and reports back `COMPLETED` or `FAILED`. Conductor durably persists the result, then advances the workflow to its next task. + +Two rules follow from this design: + +- The task type must match exactly between the workflow definition and the worker — otherwise the task sits on a queue that nothing polls. +- Workers run as ordinary processes in your own infrastructure and deploy and scale independently of the Conductor server. Conductor guarantees at-least-once delivery, meaning the same task can be delivered again after a failure or timeout — so write workers to be idempotent, where running the same task twice produces the same result. + +```mermaid +flowchart LR + subgraph server["Conductor server"] + wf["greetings workflow"] --> task["greet task (SIMPLE)"] + end + queue[["greet queue"]] + subgraph worker["Your worker"] + fn["greet(name)

+ +Save as `quickstart.py`: + +```python +from conductor.client.automator.task_handler import TaskHandler +from conductor.client.configuration.configuration import Configuration +from conductor.client.orkes_clients import OrkesClients +from conductor.client.workflow.conductor_workflow import ConductorWorkflow +from conductor.client.worker.worker_task import worker_task + + +@worker_task(task_definition_name="greet", register_task_def=True) +def greet(name: str) -> dict: + return {"result": f"Hello {name}"} + + +def main(): + config = Configuration() + clients = OrkesClients(configuration=config) + executor = clients.get_workflow_executor() + + workflow = ConductorWorkflow(name="greetings", version=1, executor=executor) + greet_task = greet(task_ref_name="greet_ref", name=workflow.input("name")) + workflow >> greet_task + workflow.output_parameters({"result": greet_task.output("result")}) + workflow.register(overwrite=True) + + with TaskHandler(configuration=config, scan_for_annotated_workers=True) as handler: + handler.start_processes() + run = executor.execute(name="greetings", version=1, workflow_input={"name": "Conductor"}) + print(run.output["result"]) + + +if __name__ == "__main__": + main() +``` + +

3. Run and verify

+ +```bash +python quickstart.py +# Hello Conductor +``` + +See the [Python SDK guide](../documentation/clientsdks/python-sdk.md) for worker configuration and production patterns. + +
+ + + + + + + + +
+ + + +## Verify durable execution + +1. Open the Conductor UI (`http://localhost:8080` for the local server) and go to **Executions → Workflow** in the left navigation. Click the newest `greetings` execution — the completed `greet_ref` task in the timeline shows `result: Hello Conductor`. +2. Now watch durability at work. Your quickstart app exited after printing, so no worker is running. Start another execution with the CLI alone: + + ```bash + conductor workflow start -w greetings -i '{"name":"Conductor"}' + ``` + +3. Refresh the executions list: the new run is `RUNNING` and `greet_ref` is `SCHEDULED` — durably queued, waiting for a worker. Nothing is lost. +4. Run your quickstart app again. The worker polls, the waiting task completes, and the execution finishes with `result: Hello Conductor`. + +**Troubleshooting** + +- `greet_ref` stays `SCHEDULED` even with the app running: the worker is not polling the `greet` task type — confirm the worker is running and its task type is exactly `greet`. +- Registration says the definition already exists: bump the version or update the local test definition. +- `greet_ref` is `FAILED`: inspect the task's input, output, and failure reason in the UI, fix the worker, and start a new execution. + +## Keep learning + +**Next:** [Run your first agent](first-agent.md) — the same durable execution model, applied to an LLM-powered agent. + +Prefer no code?

A local time that does not exist during a spring-forward transition is skipped by the cron engine; repeated local times follow the engine's next-instant calculation. Test business-sensitive schedules around DST boundaries. + +The preview endpoint accepts no timezone parameter. It evaluates in `conductor.scheduler.schedulerTimeZone` (UTC by default), not a schedule's `zoneId`, and returns at most five times even if `limit` is larger. + +## Catch up and bound execution + +`runCatchupScheduleInstances: true` advances through missed cron slots after downtime. It can create a burst, so the workflow and dependencies must be idempotent and capacity-aware. With the default `false`, the scheduler advances from current time rather than replaying every missed slot. + +Use `scheduleStartTime` and `scheduleEndTime` as epoch-millisecond inclusive bounds. A schedule outside its window stops producing new runs; it is not deleted automatically. + +## Inputs added by the scheduler + +The scheduler copies `startWorkflowRequest.input`, then adds these values to every execution: + +| Input | Meaning | +|---|---| +| `_startedByScheduler` | Schedule name | +| `_scheduledTime` | Intended cron slot, epoch milliseconds | +| `_executedTime` | Actual dispatch time, epoch milliseconds | +| `_executionId` | Unique scheduler execution-record ID | +| `_schedulerCron` | Cron expression and zone that produced this run | + +Use `${workflow.input._executionId}` when a downstream system needs per-run identity. `startWorkflowRequest.correlationId` is copied literally; the scheduler does **not** interpolate `${scheduledTime}` or other templates in it. If every workflow execution needs a unique correlation ID, derive it in the workflow from injected input or start the workflow through code that constructs the ID. + +## Operate schedules + +```bash +conductor schedule list +conductor schedule pause every-minute-demo-schedule +conductor schedule resume every-minute-demo-schedule +conductor schedule delete every-minute-demo-schedule +``` + +REST also supports filtering, search, a pause reason, and scheduled-execution history: + +```bash +curl 'http://localhost:8080/api/scheduler/schedules/search?paused=false&size=20' +curl 'http://localhost:8080/api/scheduler/search/executions?freeText=every-minute-demo-schedule&size=20' +``` + +After pausing, verify the stored `paused` state and confirm no new execution appears after a cron slot. After resuming, confirm a new scheduled execution and inspect all five injected fields. + +## Limitations + +- There is no native overlap policy. If a prior workflow is still running, the next slot can start another execution. +- There is no scheduler endpoint for "run now" or manual backfill. Start the target workflow directly for an ad hoc run and pass the intended window explicitly. +- Preview is single-cron, capped at five, and uses the server scheduler timezone. +- Java, Python, TypeScript, and Go SDKs can call the REST surface through generated or low-level clients, but this repository does not define a consistent high-level scheduler API across all SDKs. Treat REST as the portable complete interface. +- `correlationId` is literal, not a schedule template. + +For runnable catchup, bounded, concurrency, input, retry, and multi-step variants, use the [scheduled workflow recipes](../../cookbook/workflow-scheduling.md), which reuse `scheduler/examples/`. + + + + + + + + + + + + + + +# Event-Driven Orchestration + +
+
+

Event-driven orchestration connects workflows to the messages around them. A workflow can publish to a broker, an incoming message or webhook can start or advance workflows, and a signal can resume one specific execution that is waiting. Each page in this section covers one of those directions, and the table below routes you to the right one.

+
+ + Event-driven orchestration paths + A workflow publishes to a broker, which an event handler can route to a workflow or task. A webhook is verified HTTP ingress, while a signal directly advances a blocked wait task. + + WorkflowEVENT + + Brokertopic or queue + + Handlerstart or update + Webhookverified HTTP + + Durable workstart or resume + Signal caller + + Blocked WAIT + + continue + +
+ +| Need | Start here | Availability | +|---|---|---| +| Publish workflow data to a queue or broker | [Publish events](publish-events.md) | OSS and Orkes | +| Consume a broker message and start or update workflow work | [Consume and route events](consume-route-events.md) | OSS and Orkes | +| Receive an HTTP callback from an external service | [Incoming webhooks](incoming-webhooks.md) | Orkes only | +| Continue a workflow blocked on `WAIT` | [Send signals to workflows](../cookbook/sending-signals.md) | OSS and Orkes | +| Notify external systems when executions change state | [Workflow status events](workflow-status-events.md) | OSS and Orkes | + +`EVENT` publishes messages; an event handler consumes and routes them. A webhook is HTTP ingress, not a general-purpose event handler. A signal changes an existing workflow and does not create a new execution. + +## Broker provider matrix + +Provider support depends on the Conductor distribution and enabled server integration. The destination after the first colon in an event name is provider-specific. + +| Provider | OSS Conductor | Orkes | +|---|:---:|:---:| +| Conductor internal queue | Yes | — | +| Kafka | Yes | Yes | +| Amazon SQS | Yes | Yes | +| NATS | Yes | Yes | +| NATS JetStream | Yes | — | +| NATS Streaming | Yes | — | +| AMQP queue / exchange | Yes | Yes (including RabbitMQ) | +| Azure Service Bus | — | Yes | +| Google Cloud Pub/Sub | — | Yes | +| IBM MQ | — | Yes | + +## Operate the whole path + +Monitor broker queue depth (`event_queue_depth`), message processing (`event_queue_messages_processed`, `event_queue_messages_handled`, and `event_queue_messages_error`), and handler actions (`event_execution_success` and `event_execution_error`). Then check the resulting workflow or task: broker acknowledgement alone does not prove the downstream action reached its intended state. + +## Next steps + +- **[Publish events](publish-events.md)** — send workflow data to a broker. +- **[Consume and route events](consume-route-events.md)** — start or advance workflows from incoming messages. +- **[Incoming webhooks](incoming-webhooks.md)** — accept verified HTTP callbacks. +- **[Send signals](../cookbook/sending-signals.md)** — advance an execution that is waiting. +- **[Workflow status events](workflow-status-events.md)** — notify external systems as executions change state. + + + +# Production path for durable workflows + +Use this guide after [your first workflow](../../quickstart/first-workflow.md). It turns a successful local run into a service with an explicit contract, bounded failure behavior, repeatable deployment, and an operating model. + +## Outcome + +You will have a workflow whose callers know its input and output contract, whose tasks have deliberate reliability settings, and whose operators know how to inspect and recover an execution. + +## 1. Define the contract + +Treat a workflow definition and its `outputParameters` as an API. Document required inputs, validate or reject invalid requests at the boundary, and keep outputs stable for callers. When a change is not backward compatible, register a new workflow version instead of changing an active definition in place. + +Read [workflow definitions](../concepts/workflows.md), [task inputs](../how-tos/Tasks/task-inputs.md), and [workflow versioning](../how-tos/Workflows/versioning-workflows.md) before publishing a caller-facing workflow. + +## 2. Make the failure policy explicit + +For every external side effect, decide whether it is safe to retry and how it is made idempotent. Set task retry behavior and timeouts deliberately; use a failure workflow or compensation when a later failure requires business rollback. Bound the workflow itself when the business operation has a maximum acceptable duration. + +Verify the design by forcing one transient task failure and confirming that the expected retry, timeout, or compensation path is visible in the execution. + +Continue with [task timeouts and retries](../cookbook/task-timeouts-and-retries.md), [error handling](../how-tos/Workflows/handling-errors.md), and [best practices](../bestpractices.md). + +## 3. Test the real boundaries + +Test the registered definition with representative input, not only worker functions in isolation. Cover success, retryable failure, terminal business failure, timeout, and the idempotency behavior of each side effect. Use real dependencies or Testcontainers where practical so queue, persistence, and concurrency behavior is exercised. + +**Verification:** start the workflow with a test correlation ID, inspect its full execution, and assert its output contract and terminal status. + +## 4. Deploy definitions and workers safely + +Deploy worker code and task definitions before routing production traffic to a workflow that needs them. Keep workers idempotent because Conductor delivery is at least once. Roll out a new workflow version, update callers deliberately, and retain the old version until its executions are drained. + +Use [creating workflows](../how-tos/Workflows/creating-workflows.md), [scaling workers](../how-tos/Workers/scaling-workers.md), and [deployment](../running/deploy.md) for the implementation details. + +## 5. Operate the execution + +Give operators a workflow name, version, correlation-ID convention, and owner. Monitor queue depth, task failures, timeouts, and execution status. During an incident, inspect the failed task before retrying; retry only failures that are safe to repeat, then pause, resume, rerun, or terminate according to the business policy. + +**Recovery drill:** intentionally leave a workflow waiting or fail a retryable task, then find it through [searching workflows](../how-tos/Workflows/searching-workflows.md) and recover it with the documented [debugging](../how-tos/Workflows/debugging-workflows.md) controls. + +## Next production step + +For platform-level deployment and storage choices, continue to [Deploy Conductor](../running/deploy.md) and [Durable Execution](../../architecture/durable-execution.md). For an AI workflow or agent, add the controls in [Production Agent Architecture](../ai/production-agent-architecture.md) to this workflow baseline. + + + +# Handling Workflow Errors + +In production microservice architectures, failures are inevitable. Conductor provides multiple layers of error handling so you can build resilient, self-healing workflows: + +* **Saga pattern** — run a compensation flow to undo completed steps when a workflow fails. +* **Retry strategies** — automatically retry failed tasks with configurable backoff. +* **Task-level error handling** — mark tasks as optional, fail immediately on terminal errors, or set per-task timeouts. +* **Timeout policies** — control what happens when a task or workflow exceeds its time limit. +* **Workflow status listener** — send notifications to external systems on workflow completion or failure. + +## Saga pattern: compensation on failure + +The saga pattern is a well-established approach for managing distributed transactions across microservices. Instead of a single atomic transaction that spans multiple services, a saga breaks the work into a sequence of local transactions. Each step has a corresponding **compensating action** that undoes its effect. When any step in the sequence fails, the previously completed steps are rolled back in reverse order by executing their compensating actions. + +This pattern is essential in microservice architectures where two-phase commits are impractical. Because each service owns its own data, you cannot rely on a traditional database transaction to maintain consistency across services. The saga pattern gives you eventual consistency with explicit rollback logic, making failures predictable and recoverable. + +### Configuring a failure workflow + +You can configure a workflow to automatically run upon failure by adding the `failureWorkflow` parameter to your main workflow definition. +Additionally, you may also specify the _version_ of it by using the `failureWorkflowVersion` parameter. + +```json +"failureWorkflow": "", +"failureWorkflowVersion": 2, +``` + +If your main workflow fails, Conductor will trigger this failure workflow. By default, the following parameters are passed to the failure workflow as input: + +* **`reason`** — The reason for the workflow's failure. +* **`workflowId`** — The failed workflow's execution ID. +* **`failureStatus`** — The failed workflow's status. +* **`failureTaskId`** — The execution ID for the task that failed in the workflow. +* **`failedWorkflow`** — The full workflow execution JSON for the failed workflow. + +You can use these parameters to implement compensation actions in the failure workflow, such as notification alerts, resource clean-up, or reversing completed transactions. + +### Example: Slack notification on failure + +Here is a failure workflow that sends a Slack message when the main workflow fails. It posts the `reason` and `workflowId` so the team can debug the failure: + +```json +{ + "name": "shipping_failure", + "description": "Notification workflow for shipping workflow failures", + "version": 1, + "tasks": [ + { + "name": "slack_message", + "taskReferenceName": "send_slack_message", + "inputParameters": { + "http_request": { + "headers": { + "Content-type": "application/json" + }, + "uri": "https://hooks.slack.com/services/<_unique_Slack_generated_key_>", + "method": "POST", + "body": { + "text": "workflow: ${workflow.input.workflowId} failed. ${workflow.input.reason}" + }, + "connectionTimeOut": 5000, + "readTimeOut": 5000 + } + }, + "type": "HTTP", + "retryCount": 3 + } + ], + "restartable": true, + "workflowStatusListenerEnabled": false, + "ownerEmail": "conductor@example.com", + "timeoutPolicy": "ALERT_ONLY" +} +``` + +### Example: saga compensation for order processing + +A realistic saga implementation involves a main workflow that processes an order through multiple services and a compensation workflow that reverses each completed step if any step fails. + +**Main workflow** — `order_processing` processes a customer order through three stages: charge the payment, reserve inventory, and arrange shipping. + +```json +{ + "name": "order_processing", + "description": "Process a customer order through payment, inventory, and shipping", + "version": 1, + "failureWorkflow": "order_compensation", + "tasks": [ + { + "name": "charge_payment", + "taskReferenceName": "charge_payment_ref", + "inputParameters": { + "orderId": "${workflow.input.orderId}", + "customerId": "${workflow.input.customerId}", + "amount": "${workflow.input.totalAmount}" + }, + "type": "SIMPLE", + "retryCount": 2, + "retryLogic": "EXPONENTIAL_BACKOFF", + "retryDelaySeconds": 5 + }, + { + "name": "reserve_inventory", + "taskReferenceName": "reserve_inventory_ref", + "inputParameters": { + "orderId": "${workflow.input.orderId}", + "items": "${workflow.input.items}", + "paymentTransactionId": "${charge_payment_ref.output.transactionId}" + }, + "type": "SIMPLE", + "retryCount": 2, + "retryLogic": "FIXED", + "retryDelaySeconds": 3 + }, + { + "name": "arrange_shipping", + "taskReferenceName": "arrange_shipping_ref", + "inputParameters": { + "orderId": "${workflow.input.orderId}", + "shippingAddress": "${workflow.input.shippingAddress}", + "items": "${workflow.input.items}", + "inventoryReservationId": "${reserve_inventory_ref.output.reservationId}" + }, + "type": "SIMPLE", + "retryCount": 1, + "retryLogic": "FIXED", + "retryDelaySeconds": 10 + } + ], + "restartable": true, + "workflowStatusListenerEnabled": true, + "ownerEmail": "order-team@example.com", + "timeoutPolicy": "TIME_OUT_WF", + "timeoutSeconds": 600 +} +``` + +**Compensation workflow** — `order_compensation` reverses each completed step in reverse order: cancel the shipment, restore inventory, and refund the payment. + +```json +{ + "name": "order_compensation", + "description": "Undo completed order steps when order_processing fails", + "version": 1, + "tasks": [ + { + "name": "cancel_shipment", + "taskReferenceName": "cancel_shipment_ref", + "inputParameters": { + "orderId": "${workflow.input.failedWorkflow.input.orderId}", + "shipmentId": "${workflow.input.failedWorkflow.tasks[arrange_shipping_ref].output.shipmentId}" + }, + "type": "SIMPLE", + "optional": true, + "retryCount": 3, + "retryLogic": "FIXED", + "retryDelaySeconds": 5 + }, + { + "name": "restore_inventory", + "taskReferenceName": "restore_inventory_ref", + "inputParameters": { + "orderId": "${workflow.input.failedWorkflow.input.orderId}", + "reservationId": "${workflow.input.failedWorkflow.tasks[reserve_inventory_ref].output.reservationId}" + }, + "type": "SIMPLE", + "optional": true, + "retryCount": 3, + "retryLogic": "FIXED", + "retryDelaySeconds": 5 + }, + { + "name": "refund_payment", + "taskReferenceName": "refund_payment_ref", + "inputParameters": { + "orderId": "${workflow.input.failedWorkflow.input.orderId}", + "transactionId": "${workflow.input.failedWorkflow.tasks[charge_payment_ref].output.transactionId}", + "amount": "${workflow.input.failedWorkflow.input.totalAmount}" + }, + "type": "SIMPLE", + "retryCount": 5, + "retryLogic": "EXPONENTIAL_BACKOFF", + "retryDelaySeconds": 10 + } + ], + "restartable": true, + "workflowStatusListenerEnabled": false, + "ownerEmail": "order-team@example.com", + "timeoutPolicy": "ALERT_ONLY", + "timeoutSeconds": 1200 +} +``` + +Notice that compensation tasks are marked `optional: true` for steps that may not have completed before the failure occurred. The refund task uses aggressive retries with exponential backoff because it is critical that the customer receives their money back. + +## Retry strategies + +When a task fails, Conductor can automatically retry it according to the retry logic configured on the task definition. You control the retry behavior with three parameters: + +* **`retryCount`** — Maximum number of retry attempts. +* **`retryLogic`** — The backoff strategy between retries. +* **`retryDelaySeconds`** — The base delay between retries, in seconds. + +### FIXED + +Retries at a constant interval. Every retry waits the same amount of time. + +```json +{ + "retryCount": 3, + "retryLogic": "FIXED", + "retryDelaySeconds": 5 +} +``` + +This retries up to 3 times, waiting exactly 5 seconds between each attempt. + +### EXPONENTIAL_BACKOFF + +Each retry waits exponentially longer than the previous one. The delay is calculated as `retryDelaySeconds * 2^(attemptNumber)`. This reduces load on downstream services that may be experiencing pressure. + +```json +{ + "retryCount": 4, + "retryLogic": "EXPONENTIAL_BACKOFF", + "retryDelaySeconds": 2 +} +``` + +This retries up to 4 times with delays of approximately 2, 4, 8, and 16 seconds. + +### LINEAR_BACKOFF + +Each retry waits incrementally longer by a fixed amount. The delay is calculated as `retryDelaySeconds * attemptNumber`. This provides a gentler ramp-up than exponential backoff. + +```json +{ + "retryCount": 4, + "retryLogic": "LINEAR_BACKOFF", + "retryDelaySeconds": 5 +} +``` + +This retries up to 4 times with delays of approximately 5, 10, 15, and 20 seconds. + +### Choosing a retry strategy + +| Strategy | Delay pattern | Best for | +|---|---|---| +| `FIXED` | Constant (e.g., 5s, 5s, 5s) | Predictable transient failures like brief network blips or short-lived lock contention. | +| `EXPONENTIAL_BACKOFF` | Doubling (e.g., 2s, 4s, 8s, 16s) | Rate-limited APIs, overloaded services, or any case where you want to reduce pressure on a struggling dependency. | +| `LINEAR_BACKOFF` | Incremental (e.g., 5s, 10s, 15s, 20s) | Moderate recovery scenarios where you need longer waits over time but exponential growth would be too aggressive. | + +## Task-level error handling + +Beyond retries, Conductor provides several task-level controls for managing failures within a running workflow. + +### Optional tasks + +Setting `optional` to `true` on a task tells Conductor to continue the workflow even if that task fails after exhausting all retries. The workflow will proceed to the next task rather than failing entirely. + +```json +{ + "name": "send_analytics_event", + "taskReferenceName": "send_analytics_ref", + "type": "SIMPLE", + "optional": true, + "retryCount": 2, + "retryLogic": "FIXED", + "retryDelaySeconds": 3 +} +``` + +Use optional tasks for non-critical side effects like logging, analytics, or notifications where a failure should not block the primary business logic. + +### Failing immediately with terminal errors + +When a worker encounters an error that no amount of retrying will fix, such as invalid input data or a business rule violation, it should return a `FAILED_WITH_TERMINAL_ERROR` status. This tells Conductor to skip all remaining retries and fail the task immediately. + +Workers signal this by setting the task status to `FAILED_WITH_TERMINAL_ERROR` in the task result. This avoids wasting time on retries when the failure is deterministic. For example, if a payment is declined due to insufficient funds, retrying the same charge will never succeed. + +### Per-task timeout configuration + +You can set timeouts on individual tasks to prevent them from blocking the workflow indefinitely: + +```json +{ + "name": "call_external_api", + "taskReferenceName": "call_api_ref", + "type": "SIMPLE", + "timeoutSeconds": 120, + "responseTimeoutSeconds": 60, + "timeoutPolicy": "RETRY" +} +``` + +* **`timeoutSeconds`** — Maximum total time for the task, including all retries. +* **`responseTimeoutSeconds`** — Maximum time to wait for a worker to pick up and respond to the task. If a worker does not update the task within this window, Conductor marks it as timed out. + +## Timeout policies + +Timeout policies determine what Conductor does when a task exceeds its `timeoutSeconds` or `responseTimeoutSeconds` limit. + +### RETRY + +Re-queue the task for another attempt. The retry counts against the task's `retryCount`. + +```json +{ + "timeoutPolicy": "RETRY", + "timeoutSeconds": 60, + "retryCount": 3 +} +``` + +### TIME_OUT_WF + +Fail the entire workflow immediately when the task times out. Use this for tasks where a timeout indicates a critical problem that makes continuing the workflow pointless. + +```json +{ + "timeoutPolicy": "TIME_OUT_WF", + "timeoutSeconds": 300 +} +``` + +### ALERT_ONLY + +Log an alert but allow the task to continue running. The task is not terminated or retried. This is useful for long-running tasks where you want visibility into slow execution without interrupting work. + +```json +{ + "timeoutPolicy": "ALERT_ONLY", + "timeoutSeconds": 600 +} +``` + +### Choosing a timeout policy + +| Policy | Behavior on timeout | Best for | +|---|---|---| +| `RETRY` | Retries the task (counts against `retryCount`) | Tasks that may hang due to transient issues like network timeouts or unresponsive workers. | +| `TIME_OUT_WF` | Fails the entire workflow | Critical tasks where a timeout means the workflow cannot produce a valid result. | +| `ALERT_ONLY` | Logs an alert, task keeps running | Long-running or best-effort tasks where you want monitoring without enforcement. | + +## Implement a Workflow Status Listener + +Using a Workflow Status Listener, you can send a notification to an external system or an event to Conductor's internal queue upon failure. Here is the high-level overview for using a Workflow Status Listener: + +1. Set the `workflowStatusListenerEnabled` parameter to true in your main workflow definition: + ```json + "workflowStatusListenerEnabled": true, + ``` +2. Implement the [WorkflowStatusListener interface](https://github.com/conductor-oss/conductor/blob/1be02a711dc20682718c6111c09d2b02ce7edde2/core/src/main/java/com/netflix/conductor/core/listener/WorkflowStatusListener.java#L20) to plug into a custom notification or eventing system upon workflow failure. + + + +# Search executions + +Search when you know attributes such as workflow name, status, correlation ID, or time range but not the workflow ID. + +## Search with the CLI + +```bash +conductor workflow search -w order_processing -s FAILED -c 20 +conductor workflow search -s COMPLETED \ + --start-time-after "2026-07-01" --start-time-before "2026-07-31" +``` + +| CLI option | Filters or controls | Example | +|---|---|---| +| `-w`, `--workflow` | Workflow name | `--workflow order_processing` | +| `-s`, `--status` | Execution status | `--status FAILED` | +| `-c`, `--count` | Number of executions returned (maximum 1000) | `--count 20` | +| `--start-time-after` | Executions started after a timestamp | `--start-time-after "2026-07-01"` | +| `--start-time-before` | Executions started before a timestamp | `--start-time-before "2026-07-31"` | +| `--json` | JSON output instead of the table view | `--json` | +| `--csv` | CSV output instead of the table view | `--csv` | + +Results should include `workflowId`, name, status, and start time. Use the returned ID with `conductor workflow get-execution -c` before taking a recovery action. + +For structured/free-text or task-based searches beyond CLI flags, use `GET /api/workflow/search` or `GET /api/workflow/search-by-tasks`; the [Workflow API](../../../documentation/api/workflow.md#search-workflows) owns the query syntax and pagination contract. + +### REST query parameters + +`GET /api/workflow/search` accepts the following query parameters: + +| Parameter | Meaning | Default | +|---|---|---| +| `start` | Page offset | `0` | +| `size` | Number of results | `100` | +| `sort` | Sort order as `:ASC` or `:DESC` | None | +| `freeText` | Full-text search query | `*` | +| `query` | SQL-like filter expression | None | +| `classifier` | Filter or group agent workflow executions by classifier | None | +| `topLevelOnly` | Limit results to top-level workflow executions | `false` | + +## Search with the UI + +Go to **Executions > Workflow** in the Conductor UI.

Search results identify candidates; always inspect the execution before retrying, restarting, or terminating it. Continue with [View executions](viewing-workflow-executions.md) or [Debug and recover](debugging-workflows.md). + + + +# Debugging Workflows + +The [workflow execution views](viewing-workflow-executions.md) in the Conductor UI are useful for debugging workflow issues.

Fix the underlying worker, dependency, credentials, or definition before changing execution state. + +When you view the workflow execution details, the cause of the workflow failure will be stated at the top. Go to the **Tasks > Diagram** tab to quickly identify the failed task, which is marked in red. You can select the failed task to investigate the details of the failure. + +The following tab views or fields in the task details are useful for debugging: + +| Field or Tab Name | Description | +|-------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------| +| _Reason for Incompletion_ in **Task Detail** > **Summary** | The worker's error message, or the engine's message when the task timed out or was terminated. See [Understanding reasonForIncompletion](#understanding-reasonforincompletion). | +| _Worker_ in **Task Detail** > **Summary** | Contains the worker instance ID where the failure occurred. Useful for digging up detailed logs, if it has not already captured by Conductor. | +| **Task Detail** > **Input** | Useful for verifying if the task inputs were correctly computed and provided to the task. | +| **Task Detail** > **Output** | Useful for verifying what the task produced as output. | +| **Task Detail** > **Logs** | Contains the task logs, if supplied by the task worker. | +| **Task Detail** > **Retried Task - Select an instance** | (If the task has been retried multiple times) Contains all retry attempts in a dropdown list. Each list item contains the task details for a particular attempt. | + + +![Debugging Workflow Execution](workflow_debugging.png) + +## Understanding reasonForIncompletion + +`reasonForIncompletion` is a free-text field on both task and workflow executions. It is empty while an execution is healthy and is filled in when the execution stops without succeeding. The UI shows it as **Reason for Incompletion** in the task summary and at the top of the workflow execution view, and search results (`WorkflowSummary`, `TaskSummary`) include it. + +### Who writes it + +| Writer | What it contains | +|---|---| +| Your worker | Whatever the worker sets in `TaskResult.reasonForIncompletion` when it returns `FAILED` or `FAILED_WITH_TERMINAL_ERROR`. The SDKs set it to the exception message when a worker throws. | +| Event handler `fail_task` action | The action's `reasonForIncompletion` value; empty if the action does not set one. | +| System tasks | Their own error text. For example the HTTP task records the response body on a non-2xx response, `No response from the remote service`, `Missing HTTP URI. See documentation for HttpTask for required input parameters`, or `Failed to invoke HTTP task due to: `. | +| The engine | Timeouts, terminations, and definition errors, using the templates below. | + +### Engine-generated messages + +| Situation | Message | +|---|---| +| Task exceeded `timeoutSeconds` | `Task timed out after {elapsed} seconds.

This option is useful if the workflow definition has changed and you want to run the execution instance using the original definition. | +| Restart with Latest Definitions | Restart the workflow from the beginning using the latest workflow definition. This option is useful if changes were made to the workflow definition and you want to run the execution instance with the latest definition. | +| Rerun from a specific task | Re-execute the workflow from a specific task, reusing the outputs of all prior tasks. This option is useful when a task in the middle of the workflow failed and you want to fix and re-run it without re-executing everything before it. | +| Retry - From failed task | Retry the workflow from the last failed task. | + +CLI equivalents: + +```bash +conductor workflow retry +conductor workflow restart +conductor workflow rerun --task-id +``` + +After recovery, run `conductor workflow status ` and verify that the expected task is running or the workflow reached the intended terminal status. + +!!! Note + You can set tasks to be retried automatically in case of transient failures. Refer to [Task Definition](../../../documentation/configuration/taskdef.md) for more information. + +### Using Conductor UI + +**To recover from failure**: + +1. In the workflow execution details page, select **Actions** in the top right corner. +2. Select one of the following options: + - Restart with Current Definitions + - Restart with Latest Definitions + - Rerun from a specific task + - Retry - From failed task + +### Using APIs + +You can restart workflow executions using the Restart Workflow API (`POST api/workflow/{workflowId}/restart`) or the Bulk Restart Workflow API (`POST api/workflow/bulk/restart`). + +You can rerun a workflow from a specific task using the Rerun Workflow API (`POST api/workflow/{workflowId}/rerun`) with a request body specifying the `reRunFromTaskId`. + +Likewise, you can retry workflow executions from the last failed task using the Retry Workflow API (`POST api/workflow/{workflowId}/retry`) or the Bulk Retry Workflow API (`POST api/workflow/bulk/retry`). + +All three recovery operations — restart, rerun, and retry — work on workflows in any terminal state (COMPLETED, FAILED, TIMED_OUT, TERMINATED) and are available indefinitely. Conductor preserves the full execution history, so you can replay any workflow even months after the original run. + +## Limitations and next step + +Recovery can repeat side effects. Retry or rerun only when completed external operations are idempotent or have an explicit compensation policy. Continue with [Reliability and error handling](handling-errors.md) to make transient recovery automatic. + + + +# Task Lifecycle + +During a workflow execution, each task transitions through a series of states.

This page covers when to create a new version, how versions behave at runtime, and how to roll one out without disrupting ongoing executions. + +## When to version workflows + +Create a new version when inputs, outputs, task order, or failure behavior change in a way callers can observe. See [Update and version safely](creating-workflows.md#updating-workflows) for the registration mechanics. + +Versioning is also useful for gradual rollouts. For example, suppose a new version of your core workflow adds a capability that _customerA_ requires, but _customerB_ will not be ready to adopt for another 6 months. With versioning, you can move _customerA_'s traffic to version 2 now while _customerB_ stays on version 1, and migrate _customerB_ later. + +## Runtime behavior with multiple workflow versions + +At runtime, every execution references a snapshot of the workflow definition taken when it started. Changes to a definition never affect executions that are already running. + +Here is an illustration of workflow versions at runtime, when you run workflows based on the latest version, versus when you run workflows based on a specific version. + +![Diagram of a workflow definition's versions compared to its execution version at different points in time.](workflow-versioning-at-runtime.jpg) + +In the illustration above: + +- At T1, an execution starts on version V1, so it uses the V1 definition as it exists at T1. +- At T2, version V2 is registered. New executions that start on the latest version now use V2. +- At T3, the V1 definition itself is updated in place. The execution from T1 keeps running on its T1 snapshot, while any new execution pinned to V1 uses the updated T3 definition. + +### Runtime behavior during restarts + +By default, restarts, retries, and task reruns also use the snapshot from the start of the first execution attempt. If required, you can instead restart a workflow with the latest definitions. + +Here is an illustration of workflow versions at runtime, when you restart workflows using the current definitions versus using the latest definitions. + +![Diagram of workflow versions at runtime when restarting executions.](restarting-workflows-at-runtime.jpg) + +In the illustration above: + +- Restarting the V1 execution with **current definitions** re-runs it on its original T1 snapshot, even after V2 exists and even after V1 is updated at T3. +- Restarting the V1 execution with **latest definitions** re-runs it on the newest registered version, V2. + +## Rollout procedure + +1. Register the new version instead of overwriting the version production callers use: increment the `version` field in the definition and register it. + + ```bash + conductor workflow create workflow.json + ``` + +2. Validate and mock-test it, then run a real canary execution with the version pinned: + + ```bash + conductor workflow start -w --version 2 -i '{"orderId": "test-1"}' + ``` + +3. Move callers, schedules, and parent-workflow references deliberately to the new version. +4. Compare completion, failure, latency, and outputs between the two versions. +5. Keep the previous version registered until callers have migrated and its executions no longer need restart or replay support. + +Success means new callers start the intended version while existing executions continue against their recorded definition snapshot. + +## Upgrading running workflows + +Since definition changes never affect ongoing executions, a running workflow must be explicitly upgraded if required. The upgrade is a terminate followed by a restart on the latest definitions. + +!!! warning + Terminating and restarting can repeat side effects. Prefer allowing running executions to finish on their snapshot unless the workflow is idempotent or compensation is defined. + +### Using Conductor UI + +**To upgrade a running workflow:** + +1. In the left navigation, open **Executions** and select **Workflow**, then select the ongoing execution to upgrade. +2. In the top right, select **Actions** and then **Terminate**. +3. Once terminated, select **Actions** and then **Restart with latest definitions**. + +### Using Conductor APIs + +The API approach upgrades running workflows in bulk. Terminate the executions with the Bulk Terminate API, then restart them with the Bulk Restart API, passing `useLatestDefinitions=true`: + +```bash +curl -X POST 'http://localhost:8080/api/workflow/bulk/terminate' \ + -H 'Content-Type: application/json' \ + -d '["", ""]' + +curl -X POST 'http://localhost:8080/api/workflow/bulk/restart?useLatestDefinitions=true' \ + -H 'Content-Type: application/json' \ + -d '["", ""]' +``` + +Without `useLatestDefinitions=true`, a restart uses each execution's original definition snapshot and no upgrade happens. + +## Limitations and next step + +Omitting a version at start time selects the latest registered version, which trades rollout control for convenience. Pin versions in schedules and parent workflows when deterministic deployment matters. Next, rehearse [debugging and recovery](debugging-workflows.md) for both the current and previous version. + + + +# Input/Output Schema Validation + +A schema is a contract on the shape of data crossing a boundary. Without one, a missing field is discovered by whatever task first dereferences it — usually several tasks in, as a `NullPointerException` in a worker or a silently-null `${...}` expression. With one, and with [enforcement turned on](#turning-enforcement-on), the execution is rejected at the boundary, before any side effect. + +## Where a schema attaches + +| Attachment point | Scope | Fields | +|---|---|---| +| Workflow definition | The workflow's own input and output | `WorkflowDef.inputSchema` / `outputSchema` | +| Task definition | Every use of that task, in every workflow | `TaskDef.inputSchema` / `outputSchema` | + +Put a schema on the task definition when the contract belongs to the task — every workflow calling `charge_payment` should agree on what a payment request looks like. Put it on the workflow definition when the contract belongs to the entry point, which is the case for anything triggered by an external caller. + +## Schema shape + +The schema is a `SchemaDef`, embedded in the definition: + +```json +{ + "name": "customerInput", + "version": 1, + "type": "JSON", + "data": { + "$schema": "https://json-schema.org/draft/2020-12/schema", + "type": "object", + "properties": { + "customerId": { "type": "string" }, + "tier": { "type": "string", "enum": ["standard", "premium"] } + }, + "required": ["customerId"], + "additionalProperties": false + } +} +``` + +| Field | Meaning | +|---|---| +| `name` | Identifier for the schema | +| `version` | Which registered version to validate against. Omit it to follow the registry's latest; name one to pin it. Ignored for an inline `data` schema, which is the document | +| `type` | `JSON`, `AVRO`, or `PROTOBUF` | +| `data` | The schema document itself | +| `externalRef` | A name for a schema held outside Conductor. Stored and returned unchanged; **nothing dereferences it**, so it is not an alternative to inline `data` | + +## Attaching it to a workflow + +```json +{ + "name": "order_fulfillment", + "version": 1, + "ownerEmail": "team@example.com", + "schemaVersion": 2, + "enforceSchema": true, + "inputSchema": { + "name": "customerInput", + "version": 1, + "type": "JSON", + "data": { + "$schema": "https://json-schema.org/draft/2020-12/schema", + "type": "object", + "properties": { "customerId": { "type": "string" } }, + "required": ["customerId"], + "additionalProperties": false + } + }, + "tasks": [] +} +``` + +Two fields are easy to confuse. `schemaVersion` is unrelated to any of this — it is the workflow definition *format* version and should be `2`. `enforceSchema` is the per-definition switch, and it is the whole of the decision: there is no server-level setting. On `WorkflowDef` it defaults to `true`, so a workflow definition that declares an `inputSchema` is validated unless you explicitly set it to `false`. On `TaskDef` it defaults to `false`, so a task opts in. + +Register it the usual way — schemas travel inside the definition, so there is no separate step: + +```shell +curl -X PUT "$CONDUCTOR_SERVER_URL/metadata/workflow" \ + -H 'Content-Type: application/json' \ + -d '[ ... definition above ... ]' +``` + +## Referring to a registered schema + +Instead of inlining `data`, a definition can name a schema held in the [Schema Registry](schema-registry.md). Whether you also name a `version` decides whether the definition follows the registry or is pinned to one document: + +```json +"inputSchema": { "name": "customerInput", "type": "JSON" } +``` + +Omitting `version` **follows the registry's latest**. Register a new version and this definition validates against it on its next execution, with no edit to the definition. That is what you want for a contract you evolve, and what you do not want if a new version must not change how existing workflows behave. + +```json +"inputSchema": { "name": "customerInput", "type": "JSON", "version": 2 } +``` + +Naming a `version` **pins that document**. Later versions are ignored; the definition keeps validating against version 2 until you change the definition. Pin when a definition has been checked against real traffic and should not move underneath you. + +Failure messages name the version that was actually applied, not the one requested, so a pinned and a following reference are distinguishable when one rejects a payload. + +## Turning enforcement on + +Enforcement is decided entirely by the definition. There is no server property to set and nothing to restart. A payload is checked when both of these hold: + +1. the definition's own `enforceSchema` is `true`; +2. a schema is actually attached at that point. + +The two defaults differ, and the difference matters when you attach a schema: + +- On a **`TaskDef`**, `enforceSchema` defaults to `false`. Attaching a schema changes nothing about how the task executes until you set the flag on the same definition, so a schema can be attached for documentation without rejecting work. +- On a **`WorkflowDef`**, it defaults to `true`. Attaching an `inputSchema` or `outputSchema` is therefore enough on its own: that definition starts being validated on its next execution. Set `enforceSchema` to `false` explicitly if you want the schema recorded but not enforced. + +Either way enforcement arrives one definition at a time, as you edit each one, rather than all at once across a deployment. + +!!! warning "Upgrading a server that already has schemas attached" + Because `enforceSchema` defaults to `true` on `WorkflowDef`, a workflow definition that already carries an `inputSchema` or `outputSchema` — attached before this server could enforce anything — starts being validated on its next execution after the upgrade, with no edit to the definition. A schema written as documentation, never checked against real traffic, becomes a gate. + + Before upgrading, list the definitions that would be affected and decide about each one: + + ```shell + curl -s "$CONDUCTOR_SERVER_URL/metadata/workflow" \ + | jq -r '.[] | select((.inputSchema != null or .outputSchema != null) and .enforceSchema != false) + | "\(.name) v\(.version)"' + ``` + + Set `enforceSchema` to `false` explicitly on any of those you are not ready to enforce; the schema stays recorded either way. `TaskDef` needs no such review — it defaults to `false`, so attached task schemas stay inert until you opt in. + +The corollary is that setting `enforceSchema` takes effect on the next execution of that definition. Set it on a definition whose schema you have not checked against real traffic and that definition starts rejecting payloads immediately, so treat it as the change it is: register the schema, confirm it matches what callers actually send, then turn the flag on. + +## When validation runs + +| Point | Effect on failure | +|---|---| +| Workflow input | The workflow does not start, and nothing is created | +| Task input | The task fails terminally, before the worker sees it | +| Task output | The task fails terminally after the worker returns | +| Workflow output | The workflow fails at completion instead of completing | + +A workflow-input failure is reported to the caller: the start request is rejected with `400` and the validation message in the body, and no execution is created. The other three happen inside a running execution, so the validation message becomes the `reasonForIncompletion` on the task or the workflow — visible in the UI and the API, without reading server logs. + +Both task failures are **terminal**, not retriable. An input that violates a schema violates it identically on the next attempt, and an output the definition refuses is the same shape whenever the task is run again — so in neither case does a retry do anything but spend the task's retry budget on the same outcome. The workflow-level failures end the execution, so retrying does not arise. + +Input validation is the valuable one: it rejects the execution before any task has run, so there is nothing to compensate for. Output validation catches a worker returning the wrong shape, which otherwise surfaces as a downstream failure far from its cause. + +## Limits, and what happens at them + +**An externalized output is not checked.** A worker that returns its output through external payload storage hands the server a storage path rather than the payload, so there is nothing in hand to validate and the check is skipped. Task input, workflow input and workflow output are unaffected; so is a task whose output is small enough to travel inline. + +**Some system task output is checked, and some is not.** A synchronous system task that finishes inside its `execute(...)` step — `INLINE`, `SET_VARIABLE` and the like — has its output validated in the decider, and fails terminally like any other task. Two kinds are not covered: an asynchronous system task such as `HTTP` or `SUB_WORKFLOW`, and a synchronous one that completes during scheduling instead. For those, an `outputSchema` on the task definition is stored and never enforced. That and the externalized output above pass quietly, and so does the unresolvable reference described below; the non-`JSON` and typeless schemas below are the ones that fail loudly instead. Every system task's *input* is validated at scheduling like any other task's, and workflow input and workflow output are unaffected. + +**A schema that is not `JSON` is refused, not skipped.** An `AVRO` or `PROTOBUF` schema is accepted at registration and returned unchanged, but this server has no validator for it — so rather than let the payload through unchecked, it fails the execution and says why. A definition that both attaches one and opts into enforcement will start failing when you turn enforcement on. + +**A schema carrying no `type`, or only an `externalRef`, is refused too.** Neither names a document this server can check against — nothing dereferences `externalRef` — so both fail the execution and say so. + +**A reference the registry does not hold stops enforcing, quietly.** A schema attached by name and version is looked up in the [Schema Registry](schema-registry.md); if nothing is registered under that name and version there is no document to validate against, so the payload goes through unchecked rather than failing. The miss increments the `schema_registry_miss` counter, tagged with the schema name — that counter is the only signal, so watch it if you rely on enforcement. A registered document the validator cannot read or use behaves the same way and is logged. The common cause is a missing `$schema` line: without it the validator cannot tell which JSON Schema version to apply, so a document that otherwise looks correct enforces nothing. Both are errors in the definition rather than in the payload, which is why neither is charged to the caller; the cost is that a reference pointing at nothing enforces nothing. + +## Writing schemas that age well + +`additionalProperties: false` deserves a moment's thought. It turns an unexpected field into a hard failure — right for a contract you own end to end, a nuisance for one where callers legitimately pass extra context. Leave it out unless you mean it. + +Adding a field to `required` is a breaking change for every existing caller. Because a running execution keeps the definition version it started with, the safe path is the same as any other definition change: register a new version rather than editing the current one. See [Managing Workflow Versions](Workflows/versioning-workflows.md). + +Keep the schema narrow. A schema that restates every optional field becomes something nobody updates, and a stale contract is worse than none.

Anything referencing that version sees the correction, which is the point and also the risk. + +Two simultaneous `newVersion=true` saves of the same name can overwrite each other. The server reads the highest version and saves one past it, with nothing between the two steps, so both writers can read the same maximum, land on the same version and leave only the later one stored. Concurrent registration under one name is last-writer-wins; serialize those saves if losing one would matter. + +Deleting is version-aware in the same way. `DELETE /api/schema/{name}/{version}` removes one version and leaves the rest of the history; `DELETE /api/schema/{name}` removes all of it. Both return `404` when there was nothing to remove, so a delete that answers `200` has actually deleted something — worth knowing if you script cleanup that runs whether or not the schema is there. + +## The management screen + +The UI has a screen for the registry, so routine work does not need `curl`. Find it under **Definitions → Schemas**, at `/schemas`. + +The list holds one row per schema rather than one per version: the name links to the editor, and the row carries the schema's type, its latest version, how many versions exist, and when it was created. Two actions sit on each row — **Clone**, which copies the contract under a new name starting again at version 1, and **Delete**, which removes the schema and every version of it. + +Opening a schema shows its body in a JSON editor, with a version selector for its history.

Replace one of those through the API. + +The input- and output-schema pickers on the Simple Task, Yield Task, Workflow Properties and Task Definition forms read the same registry, and populate as soon as the server serves `/api/schema`. On the Simple Task, Yield Task and Workflow Properties forms, a picker naming a schema the registry does not hold is flagged, so a dangling reference shows up in the editor rather than at runtime. The Task Definition form does not flag one. + +Give every JSON schema a `$schema` line, as the examples above do. Without one the server cannot tell which JSON Schema version to apply, and a definition enforcing that schema silently validates nothing. See [Input/Output Schema Validation](schema-validation.md). + +## Server properties + +The registry itself needs no configuration, and neither does enforcement: whether a definition's schema is enforced is decided by that definition's own `enforceSchema` flag, not by a server setting.

If this is more than a few seconds: + +1. **Check worker count** — if all workers are busy, add more instances. +2. **Check polling interval** — reduce it if workers aren't polling frequently enough. + +!!! warning + Reducing the polling interval increases API requests to the server. Balance responsiveness against server load. + + +## Scaling strategies + +### When to scale + +| Signal | Action | +|---|---| +| Queue depth growing steadily | Add worker instances | +| Queue wait time > 5s at p99 | Add worker instances or reduce polling interval | +| Throughput dropping while queue grows | Investigate worker health (CPU, memory, downstream dependencies) | +| Queue consistently empty, workers idle | Scale down to save resources | + +### Horizontal scaling + +Add more worker instances. Conductor distributes tasks automatically — every worker polling the same task type competes for work from the same queue. No configuration changes needed on the Conductor server. + +### Polling interval tuning + +The polling interval controls how frequently workers check for new tasks. Shorter intervals mean lower latency but higher server load. + +| Scenario | Recommended interval | +|---|---| +| Latency-sensitive tasks | 100–500ms | +| Standard processing | 1–5s | +| Batch / background work | 5–30s | + +### Thread pool sizing + +Each worker instance can run multiple polling threads. A good starting point: + +``` +threads = (task_throughput × avg_task_duration) / num_worker_instances +``` + +For I/O-bound tasks (HTTP calls, database queries), use more threads than CPU cores. For CPU-bound tasks, match thread count to available cores. + +### Rate limiting + +If downstream services have rate limits, configure task-level rate limits to prevent workers from overwhelming them: + +```json +{ + "name": "call_external_api", + "rateLimitPerFrequency": 100, + "rateLimitFrequencyInSeconds": 60 +} +``` + +This limits the task to 100 executions per 60-second window across all workers. + +### Domain isolation + +Use [task-to-domain](../../../documentation/api/taskdomains.md) to route tasks to specific worker pools. This prevents noisy neighbors — a high-volume workflow won't starve workers serving a latency-sensitive one. + + + +# Architecture Overview + +This diagram showcases an overview of Conductor's system architecture: + +![Conductor's Architecture diagram.](conductor-architecture.png) + + +In Conductor, workflows are executed on a worker-task queue architecture, where each task type (HTTP, Event, Wait, *example_simple_task* and so on) has its own dedicated task queue. The key components of Conductor’s core orchestration engine include: + +* **State machine evaluator**—Orchestrates workflows by scheduling tasks to their relevant queues and assigning them to active workers when polled. Monitors each task's state and ensures it is completed, retried, or failed as required. +* **Task queues**—Distributed queues for each task type, where tasks are completed on a first-in-first-out basis. +* **Task workers**—Poll the Conductor server via HTTP or gRPC for tasks, execute tasks, and update the server on the task status. Each worker is responsible for carrying out a specific task type. +* **Data stores** (Redis by default)—High-availability persistence stores that maintain workflow and task metadata, task queues, and execution history +* **APIs**—REST APIs for programmatic access to the Conductor server. + + +By default, Conductor uses Redis as its data store, with Elasticsearch used for its indexing backend. These [storage layers are pluggable](../../documentation/advanced/extend.md), allowing you to work with alternative backends and queue service providers. + + +## Task execution + +With a worker-task queue architecture, Conductor schedules and assigns tasks to its designated task queues based on its task type. Conductor follows an RPC-based communication model where task workers run on a separate machine from the server and communicate over HTTP-based endpoints with the server. + +The workers employ a polling model for managing their designated queues, and update Conductor with the task status. + +![Runtime Model of Conductor.](overview.png) + + + +### Worker-server polling mechanism + + +Each worker declares beforehand what task(s) it can execute. At runtime, task workers poll its designated task queue(s) to receive and execute scheduled work. Conductor passes task inputs to the worker for execution and collects the task outputs, continuing the process according to the workflow definition. + +By default, workers infinitely poll Conductor every 100ms. The polling interval value for each type of worker can be adjusted accordingly based on factors like workload. Here is the polling mechanism in detail: + +1. The application starts a workflow execution by interacting with Conductor, which returns a workflow (execution) ID. It can be used to track the workflow's progress and manage its execution. +2. Conductor schedules the first task in the workflow to its task queue. +3. The workers responsible for executing the first task within the workflow are polling Conductor for tasks to execute via HTTP or gRPC. When a task is scheduled, Conductor sends it to the next available worker, which then performs the required work. +4. Periodically, the worker returns the task status to Conductor (e.g. IN PROGRESS, FAILED, COMPLETED, etc). +5. Once the first task in the workflow instance is completed, the worker returns the task output to the server, and Conductor schedules the next set of tasks to be performed. + +Conductor manages and maintains the workflow state, keeping track of which tasks have been completed and which are still pending. This ensures that the workflow is executed correctly, with each task triggered precisely at the right time. + +Using the workflow ID, the application can check the Conductor server for the workflow status at any time. This is particularly useful for asynchronous or long-running workflows, as it allows the application to monitor the workflow's progress and take appropriate action, such as pausing or terminating the workflow if needed. + + + +# Design Patterns + +

Design patterns are complete, runnable workflow definitions for common orchestration problems. Each page takes one problem, such as parallel fan-out, sagas, timers, or human approval, and gives you a working definition to register, run, and adapt to your own tasks.

+

A signal advances a workflow that is already running and waiting. It resolves the first non-terminal WAIT task in the target execution, so the caller only needs the workflow ID. A signal never starts a new execution, cannot target an arbitrary task reference, and does not resolve HUMAN tasks.

Following them is the difference between a review about your change and a review about formatting. + +## Before you write code + +**Discuss anything non-trivial first.** A feature has usually more than one plausible design, and the cheapest place to compare them is a [discussion](https://github.com/conductor-oss/conductor/discussions) rather than a finished pull request. Showing an idea in code is welcome — just know it may be throw-away work. + +**Consider whether it belongs in the core.** Not every feature does. Weigh: + +- Does it add complexity or confusion for users who do not need it? +- Does it break backward compatibility? This is seldom acceptable. +- Does it add a dependency to a core module? This is rarely acceptable. +- Should it be opt-in? A new queue or persistence backend belongs in a separate, optionally-enabled module. +- Should it be a separate repository altogether? Integrations with other systems often should be, because their lifecycle differs from the server's. + +## Code style + +- **Run Spotless before committing.** `./gradlew spotlessApply`. CI fails on formatting, and a formatting-only diff buries the real change. +- **Design against interfaces.** Conductor is pluggable by design; new concepts should be introduced as an interface with implementations behind it. +- **Respect module boundaries.** DAO interfaces belong in `core`. Implementations belong in their own persistence module — `postgres-persistence`, `redis-persistence`, and so on. A `core` class must not reach into a specific backend. +- **Follow the surrounding code.** Match the naming, structure, and comment density of the file you are editing rather than importing a different house style. +- **Comment the non-obvious.** Explain the algorithm, the ordering constraint, the reason a check exists. Skip comments that restate the code. +- **No emojis** in code, logs, or comments. + +## Testing + +- **Avoid mocks.** Use real implementations wherever possible. A test built from mocks tends to assert that the mocks were called, not that the code works. +- **Test behaviour, not structure.** A test that re-implements the logic it is checking passes for the wrong reasons and fails whenever the implementation is refactored. +- **Use Testcontainers** for databases, caches, and other external dependencies. +- **Cover concurrency.** Much of the engine is multi-threaded; single-threaded tests miss its most important failure modes. +- **`./gradlew test` must pass** before you push. + +One thing worth internalising: some bugs only appear across a process boundary. A behaviour that works in an in-process test can still be broken in a deployed server, because the test shares a filesystem, a JVM, and a clock with the code under test. If a change touches something that crosses that boundary, prove it with an integration or end-to-end test. + +## Dependency pinning + +Some dependencies are pinned deliberately and must not be bumped as a matter of routine. `AGENTS.md` in the repo root records the current hard pins and the reason for each, along with what to check before changing one. Read it before adding or upgrading a dependency — an incidental version bump in an unrelated pull request is a common reason for a request for changes. + +## Pull requests + +- **Target `main`.** It is the stable branch and the only PR target. +- **One logical change per PR.** A focused diff is reviewed in one pass; a PR that fixes a bug, reformats a file, and bumps Gradle gets stuck on the part nobody asked for. +- **Add or update tests** for any code change. +- **Run `./gradlew spotlessApply` and `./gradlew test`** before pushing. +- **Write a descriptive commit message.** Say what changed and why. The why is the part a reader cannot reconstruct from the diff. + +Reviews can take time. The project is distributed across time zones, and maintainers have other work — a delay is not disinterest. + +## Documentation + +Documentation is derived from source, not written from memory. To document an endpoint, open the controller and copy the path from its mapping annotation. To document a CLI flag, open the command and read its flag declarations. To show output, run the thing and paste what it printed. + +If you cannot verify an example — no server available, no credentials — mark it with `` and say so in the pull request rather than leaving an unverified example looking verified. + +`CLAUDE.md` in the repo root has the per-content-type checklist and the source locations for each kind of page. + +## License + +Contributions are licensed under Apache 2.0.

A Kafka consumer can translate each record into a `POST /api/workflow/{workflowId}/messages` request using the payload shape shown above. Keep that consumer implementation in its owning SDK or service repository; it is independent of the framework used by the workflow's agent steps. ## Configuration diff --git a/e2e/src/test/java/io/conductor/e2e/schema/SchemaEnforcementE2ETest.java b/e2e/src/test/java/io/conductor/e2e/schema/SchemaEnforcementE2ETest.java new file mode 100644 index 0000000000..6e4a72ae3d --- /dev/null +++ b/e2e/src/test/java/io/conductor/e2e/schema/SchemaEnforcementE2ETest.java @@ -0,0 +1,738 @@ +/* + * Copyright 2026 Conductor Authors. + *

AI agents are moving from code generation to task execution\n\nCommon agent workflows in 2025 include:\n\n- Converting an issue or ticket into a code change\n- Navigating unfamiliar repositories\n- Generating and updating tests\n- Debugging failed builds and test suites\n- Performing dependency upgrades\n- Writing documentation and release notes\n- Creating pull requests\n- Reviewing code and suggesting fixes\n- Migrating APIs or frameworks\n- Automating repetitive maintenance work\n\nThe largest change is not simply faster code completion; it is the delegation of portions of the software-development loop.\n\n---\n\n### 2. Adoption is widespread, but usage is uneven\n\nKey adoption data:\n\n- **Stack Overflow Developer Survey 2024:** approximately **76% of developers were using or planning to use AI tools**; roughly **62% reported currently using AI assistance** in development.\n- **DORA 2024:** approximately **three-quarters of software professionals reported using AI at work**, with most users reporting perceived productivity benefits.\n- Adoption is highest for:\n - Code generation\n - Search and explanation\n - Test generation\n - Documentation\n - Debugging\n- Adoption is lower for:\n - Fully autonomous production changes\n - Security-sensitive code\n - Large architectural decisions\n - Unsupervised deployments\n\nMost organizations in 2025 still use agents with human approval gates rather than granting unrestricted production access.\n\n---\n\n### 3. Productivity gains are real for some tasks, but highly variable\n\nEvidence supports substantial gains on bounded, well-specified tasks:\n\n- A GitHub Copilot controlled experiment found developers completed a coding task approximately **55.8% faster** with Copilot. The study involved **95 developers**, but it tested an earlier autocomplete-oriented system rather than today’s more autonomous agents.\n- McKinsey estimated that generative AI could increase software-engineering productivity by roughly **20–30%**, especially in coding, testing, documentation, and maintenance. This was a potential-value estimate, not a realized industry-wide result.\n- Developers commonly report faster:\n - Boilerplate implementation\n - API usage\n - Unit-test creation\n - Repository exploration\n - Error diagnosis\n - Documentation\n\nHowever, the gains decline when tasks require extensive context, ambiguous requirements, or architectural judgment.\n\n#### Contradictory evidence\n\nA 2025 METR randomized study of experienced open-source developers found that developers using contemporary AI tools took approximately **19% longer**, despite expecting the tools to make them faster. The study involved a relatively small number of developers and selected repositories, but it demonstrated that AI assistance can impose review, correction, and coordination costs.\n\n**Interpretation:** AI agents increase local task speed more reliably than they increase end-to-end delivery speed.\n\n---\n\n### 4. The main bottleneck is shifting from writing code to reviewing and validating it\n\nAI agents can produce code faster than teams can confidently verify it.\n\nObserved consequences include:\n\n- More generated code entering pull requests\n- Larger diffs and more frequent incremental changes\n- Increased need for automated tests and static analysis\n- More reviewer time spent understanding AI-generated logic\n- Higher importance of repository documentation and coding conventions\n- Greater demand for fast CI feedback\n- More “almost correct” implementations requiring human correction\n\nDevelopers increasingly act as:\n\n- Specification writers\n- Reviewers\n- Test designers\n- System integrators\n- Agent supervisors\n- Risk owners\n\nThe value of engineering judgment becomes more important when generation becomes cheap.\n\n---\n\n### 5. Software quality effects are mixed\n\nPotential quality improvements:\n\n- More unit tests and test cases\n- Better documentation coverage\n- Faster defect diagnosis\n- More consistent refactoring\n- Automated linting and static-analysis fixes\n- Easier modernization of legacy code\n\nCommon quality problems:\n\n- Hallucinated APIs and library behavior\n- Incorrect assumptions about undocumented business rules\n- Tests that reproduce the implementation rather than validate requirements\n- Overfitting to visible test cases\n- Duplicate or unnecessary abstractions\n- Security vulnerabilities\n- Performance regressions\n- Inconsistent changes across large repositories\n- Code that compiles but is semantically wrong\n\nAI-generated code is generally strongest when:\n\n- Requirements are explicit\n- Existing examples are available\n- Tests are comprehensive\n- The task is local and repetitive\n- The agent has good repository access\n\nIt is weaker when:\n\n- Requirements are ambiguous\n- Correctness depends on domain knowledge\n- The system has poor tests\n- Changes cross many services\n- Performance or security constraints are implicit\n\n---\n\n### 6.

AI agents are moving from code generation to task execution\n\nCommon agent workflows in 2025 include:\n\n- Converting an issue or ticket into a code change\n- Navigating unfamiliar repositories\n- Generating and updating tests\n- Debugging failed builds and test suites\n- Performing dependency upgrades\n- Writing documentation and release notes\n- Creating pull requests\n- Reviewing code and suggesting fixes\n- Migrating APIs or frameworks\n- Automating repetitive maintenance work\n\nThe largest change is not simply faster code completion; it is the delegation of portions of the software-development loop.\n\n---\n\n### 2. Adoption is widespread, but usage is uneven\n\nKey adoption data:\n\n- **Stack Overflow Developer Survey 2024:** approximately **76% of developers were using or planning to use AI tools**; roughly **62% reported currently using AI assistance** in development.\n- **DORA 2024:** approximately **three-quarters of software professionals reported using AI at work**, with most users reporting perceived productivity benefits.\n- Adoption is highest for:\n - Code generation\n - Search and explanation\n - Test generation\n - Documentation\n - Debugging\n- Adoption is lower for:\n - Fully autonomous production changes\n - Security-sensitive code\n - Large architectural decisions\n - Unsupervised deployments\n\nMost organizations in 2025 still use agents with human approval gates rather than granting unrestricted production access.\n\n---\n\n### 3. Productivity gains are real for some tasks, but highly variable\n\nEvidence supports substantial gains on bounded, well-specified tasks:\n\n- A GitHub Copilot controlled experiment found developers completed a coding task approximately **55.8% faster** with Copilot. The study involved **95 developers**, but it tested an earlier autocomplete-oriented system rather than today’s more autonomous agents.\n- McKinsey estimated that generative AI could increase software-engineering productivity by roughly **20–30%**, especially in coding, testing, documentation, and maintenance. This was a potential-value estimate, not a realized industry-wide result.\n- Developers commonly report faster:\n - Boilerplate implementation\n - API usage\n - Unit-test creation\n - Repository exploration\n - Error diagnosis\n - Documentation\n\nHowever, the gains decline when tasks require extensive context, ambiguous requirements, or architectural judgment.\n\n#### Contradictory evidence\n\nA 2025 METR randomized study of experienced open-source developers found that developers using contemporary AI tools took approximately **19% longer**, despite expecting the tools to make them faster. The study involved a relatively small number of developers and selected repositories, but it demonstrated that AI assistance can impose review, correction, and coordination costs.\n\n**Interpretation:** AI agents increase local task speed more reliably than they increase end-to-end delivery speed.\n\n---\n\n### 4. The main bottleneck is shifting from writing code to reviewing and validating it\n\nAI agents can produce code faster than teams can confidently verify it.\n\nObserved consequences include:\n\n- More generated code entering pull requests\n- Larger diffs and more frequent incremental changes\n- Increased need for automated tests and static analysis\n- More reviewer time spent understanding AI-generated logic\n- Higher importance of repository documentation and coding conventions\n- Greater demand for fast CI feedback\n- More “almost correct” implementations requiring human correction\n\nDevelopers increasingly act as:\n\n- Specification writers\n- Reviewers\n- Test designers\n- System integrators\n- Agent supervisors\n- Risk owners\n\nThe value of engineering judgment becomes more important when generation becomes cheap.\n\n---\n\n### 5. Software quality effects are mixed\n\nPotential quality improvements:\n\n- More unit tests and test cases\n- Better documentation coverage\n- Faster defect diagnosis\n- More consistent refactoring\n- Automated linting and static-analysis fixes\n- Easier modernization of legacy code\n\nCommon quality problems:\n\n- Hallucinated APIs and library behavior\n- Incorrect assumptions about undocumented business rules\n- Tests that reproduce the implementation rather than validate requirements\n- Overfitting to visible test cases\n- Duplicate or unnecessary abstractions\n- Security vulnerabilities\n- Performance regressions\n- Inconsistent changes across large repositories\n- Code that compiles but is semantically wrong\n\nAI-generated code is generally strongest when:\n\n- Requirements are explicit\n- Existing examples are available\n- Tests are comprehensive\n- The task is local and repetitive\n- The agent has good repository access\n\nIt is weaker when:\n\n- Requirements are ambiguous\n- Correctness depends on domain knowledge\n- The system has poor tests\n- Changes cross many services\n- Performance or security constraints are implicit\n\n---\n\n### 6.

In 2025, a new generation of AI agents can inspect a repository, interpret an issue, modify multiple files, run tests, diagnose failures, and open a pull request.\n\nThat shift is changing software development from a process centered on writing code to one increasingly centered on directing, reviewing, and validating machine-generated work.\n\nThe result is neither the complete automation of engineering nor a minor productivity boost. AI agents are highly effective on some tasks, unreliable on others, and most valuable when they operate within well-structured development processes.\n\n## From autocomplete to task execution\n\nEarlier coding assistants primarily completed lines or generated small snippets. Modern agents can handle multi-step assignments such as:\n\n- Turning an issue or ticket into a proposed code change\n- Exploring an unfamiliar codebase\n- Creating or updating tests\n- Debugging failed builds\n- Upgrading dependencies\n- Migrating APIs or frameworks\n- Writing documentation and release notes\n- Preparing pull requests\n- Reviewing code and suggesting fixes\n- Automating repetitive maintenance work\n\nThe important change is not simply that AI writes code faster. It is that teams can now delegate portions of the software-development loop.\n\nA developer might provide an issue such as “add support for this API version,” and an agent could locate the relevant modules, update the implementation, modify tests, run the test suite, and summarize the result. Human engineers still typically decide whether the change is correct and safe, but they spend less time carrying out every intermediate step.\n\n## Adoption is widespread—but autonomy remains limited\n\nAI-assisted development has become common across the industry. Surveys in 2024 found that roughly three-quarters of software professionals were using or planning to use AI tools, with many reporting regular use for development work.\n\nThe most common applications include:\n\n- Code generation\n- Code search and explanation\n- Test creation\n- Documentation\n- Debugging\n- Refactoring\n\nUse is more cautious when an agent can affect production systems, sensitive data, or security-critical code. Most organizations continue to use approval gates rather than giving agents unrestricted access to deployment systems.\n\nIn practice, the prevailing model is **supervised autonomy**:\n\n1. The agent performs a task.\n2. Automated checks evaluate the result.\n3. A developer reviews the changes.\n4. A human approves, modifies, or rejects them.\n\nFully autonomous software delivery remains the exception rather than the norm.\n\n## Productivity gains are real—but highly variable\n\nAI agents can produce impressive gains on bounded, well-specified tasks. Developers often report faster work in areas such as:\n\n- Boilerplate implementation\n- Unit-test generation\n- API integration\n- Repository exploration\n- Error diagnosis\n- Documentation\n- Small bug fixes\n- Dependency updates\n\nA widely cited GitHub Copilot study found that developers completed a particular coding task approximately 55.8% faster when using the tool. However, that experiment involved an earlier, autocomplete-oriented system and a specific task—not the full complexity of modern software development.\n\nOther industry estimates have suggested potential productivity increases of 20–30% across activities such as coding, testing, documentation, and maintenance. These figures represent potential or task-level improvements, not guaranteed gains for every team.\n\n### Why results differ\n\nAI assistance is most effective when:\n\n- Requirements are explicit\n- The task is local and repetitive\n- Good examples already exist\n- Tests are comprehensive\n- The agent can access the relevant repository context\n- Feedback from tools such as CI is fast and reliable\n\nBenefits decline when work involves:\n\n- Ambiguous requirements\n- Complex business rules\n- Poorly documented systems\n- Cross-service changes\n- Performance constraints\n- Security-sensitive decisions\n- Architectural trade-offs\n\nA 2025 randomized study by METR offered an important counterpoint. It found that experienced open-source developers using contemporary AI tools took approximately 19% longer on selected tasks, even though they expected the tools to make them faster.\n\nThe lesson is not that AI is ineffective. Rather, local speed does not automatically translate into faster end-to-end delivery. Reviewing, correcting, testing, and coordinating AI-generated changes can offset the time saved during implementation.\n\n## The bottleneck is shifting from coding to validation\n\nAs agents generate code more quickly, teams face a new constraint: verifying that the code is correct.\n\nAI-generated changes can create:\n\n- Larger pull requests\n- More frequent incremental changes\n- Additional review work\n- Greater demand for automated testing\n- More “almost correct” implementations\n- New forms of technical debt\n\nDevelopers may spend less time typing code but more time asking:\n\n- Does this actually meet the requirement?\n- What assumptions did the agent make?\n- What cases are missing from the tests?\n- Could this create a security or performance problem?\n- Does the change fit the architecture?\n- What happens in production?\n\nThis makes engineering judgment more valuable, not less. Developers increasingly act as:\n\n- Specification writers\n- Test designers\n- Reviewers\n- System integrators\n- Agent supervisors\n- Risk owners\n\nWhen code generation becomes cheap, knowing what should be built—and recognizing when an implementation is wrong—becomes a larger part of the job.\n\n## Software quality is improving in some areas and deteriorating in others\n\nAI agents can improve quality when they are used to expand test coverage, standardize repetitive work, and identify defects. Common benefits include:\n\n- More unit tests\n- Faster defect diagnosis\n- Better documentation coverage\n- Automated lint and static-analysis fixes\n- More consistent refactoring\n- Faster legacy-system modernization\n\nBut generated code can also introduce serious problems:\n\n- Hallucinated APIs or library behavior\n- Incorrect assumptions about business rules\n- Tests that merely reproduce the implementation\n- Overfitting to visible test cases\n- Unnecessary abstractions\n- Security vulnerabilities\n- Performance regressions\n- Inconsistent changes across a large codebase\n\nAI-generated code may compile and pass existing tests while still being conceptually wrong. This is particularly likely when requirements are implicit or the test suite is weak.\n\nThe quality of an agent’s output depends heavily on the quality of the environment around it. A well-tested, clearly documented repository gives the agent useful constraints. A poorly structured codebase gives it room to guess.\n\n## Better repositories produce better AI results\n\nAI agents perform more reliably in codebases with:\n\n- Clear build and deployment instructions\n- Standard project structures\n- Strong automated tests\n- Explicit architecture documentation\n- Well-written issue descriptions\n- Typed interfaces\n- Small, composable modules\n- Reliable continuous integration\n- Clear ownership metadata\n- Machine-readable configuration\n\nThis creates a new incentive for organizations to treat documentation, testing, and developer tooling as productivity infrastructure.\n\nFor years, teams have sometimes viewed internal documentation and test coverage as overhead. In an agent-assisted environment, these assets become part of the interface between humans and machines. They help agents understand what the system does, what must not change, and how to verify their work.\n\n## Benchmarks show progress—but not full autonomy\n\nSoftware-engineering benchmarks such as SWE-bench have shown rapid improvements in AI systems’ ability to resolve real-world GitHub issues. Leading systems have reported solving more than half of selected issues, with some configurations exceeding 70% on particular SWE-bench Verified evaluations.\n\nThese results are significant, but benchmark performance should not be confused with production-ready autonomy.\n\nBenchmark results vary according to:\n\n- The model\n- The agent framework\n- Available tools\n- Prompting and context\n- Test execution\n- Benchmark version\n- Evaluation methodology\n\nReal software development involves much more than making tests pass. Engineers must also consider:\n\n- Security\n- Maintainability\n- Operational behavior\n- Backward compatibility\n- Product priorities\n- Communication with stakeholders\n- Incident response\n- Long-term architectural consequences\n\nBenchmarks demonstrate that agents can solve many constrained software tasks. They do not show that agents can independently manage a large, unfamiliar production system over months or years.\n\n## Security risks expand with agent capabilities\n\nAgents create greater security risks than simple code-completion tools because they can often execute commands, access repositories, modify configuration, and interact with external services.\n\nKey risks include:\n\n- Vulnerable generated code\n- Exposure of source code, credentials, or customer data\n- Prompt injection through source files, issues, or web content\n- Excessive permissions\n- Unreviewed changes to infrastructure and CI pipelines\n- Insecure dependency recommendations\n- Weak secret handling\n- Limited visibility into why an agent made a change\n\nA malicious instruction hidden in a repository file, issue description, or dependency could potentially influence an agent’s behavior. The more tools and permissions an agent has, the greater the potential impact of an error or attack.\n\nOrganizations using agents should consider:\n\n- Least-privilege access\n- Sandboxed execution\n- Secret isolation\n- Restricted network access\n- Mandatory tests and security scans\n- Detailed audit logs\n- Human approval for production-impacting actions\n- Separate permissions for reading, writing, merging, and deploying\n\nAgentic development should be treated as both a productivity initiative and a security-sensitive systems-integration project.\n\n## Junior developers face a changing learning curve\n\nAI can automate many tasks traditionally assigned to junior engineers:\n\n- Basic bug fixes\n- CRUD functionality\n- Boilerplate code\n- Simple tests\n- Documentation updates\n- Straightforward integrations\n\nThat creates an important tension. These tasks may be routine, but they also provide valuable practice. If agents perform too much entry-level work, junior developers may get fewer opportunities to learn debugging, system behavior, and software design through direct experience.\n\nNew developers will need structured opportunities to build skills in:\n\n- Requirements analysis\n- Testing and validation\n- Debugging from first principles\n- Code review\n- Security\n- System design\n- Production operations\n- Evaluating AI output\n\nAI may increase the productivity gap between developers who can critically assess generated code and those who simply accept it. Knowing how to prompt an agent is useful; knowing when its answer is wrong is more important.\n\n## Engineering metrics need to change\n\nWhen AI can generate code rapidly, traditional measures such as lines of code, commits, and tickets completed become even less meaningful.\n\nOrganizations should focus more on outcomes and delivery health, including:\n\n- Lead time for changes\n- Review latency\n- Change failure rate\n- Defect escape rate\n- Mean time to recovery\n- Rework percentage\n- Test effectiveness\n- Security findings\n- Customer-impacting incidents\n- Time from issue definition to validated release\n\nAn agent may produce hundreds of lines of code in minutes, but that does not mean the team delivered more value. The meaningful question is whether the software is correct, maintainable, secure, and useful to customers.\n\n## Where AI agents are creating the most value\n\nIn 2025, the strongest use cases tend to involve routine or maintenance-heavy work:\n\n- Legacy modernization\n- Test generation\n- Dependency upgrades\n- Framework migrations\n- Internal tools\n- Data-transformation scripts\n- API integrations\n- Documentation\n- Incident triage\n- Small bug fixes\n- Code search and explanation\n\nAgents are less reliable for:\n\n- Novel architecture\n- Safety-critical systems\n- Complex distributed-system changes\n- Poorly specified requirements\n- High-stakes security controls\n- Long-running projects with shifting goals\n\nThis suggests that the near-term economic impact will likely be uneven. AI may make more maintenance work financially practical, accelerate low-priority backlog items, and reduce the number of engineering hours required for routine features.\n\nAt the same time, organizations may place greater demand on senior engineers, technical leads, and specialists who can define requirements, assess risk, and guide system-level decisions.\n\nThere is not yet strong evidence that AI agents caused broad software-engineering employment declines in 2025.

In 2025, a new generation of AI agents can inspect a repository, interpret an issue, modify multiple files, run tests, diagnose failures, and open a pull request.\n\nThat shift is changing software development from a process centered on writing code to one increasingly centered on directing, reviewing, and validating machine-generated work.\n\nThe result is neither the complete automation of engineering nor a minor productivity boost. AI agents are highly effective on some tasks, unreliable on others, and most valuable when they operate within well-structured development processes.\n\n## From autocomplete to task execution\n\nEarlier coding assistants primarily completed lines or generated small snippets. Modern agents can handle multi-step assignments such as:\n\n- Turning an issue or ticket into a proposed code change\n- Exploring an unfamiliar codebase\n- Creating or updating tests\n- Debugging failed builds\n- Upgrading dependencies\n- Migrating APIs or frameworks\n- Writing documentation and release notes\n- Preparing pull requests\n- Reviewing code and suggesting fixes\n- Automating repetitive maintenance work\n\nThe important change is not simply that AI writes code faster. It is that teams can now delegate portions of the software-development loop.\n\nA developer might provide an issue such as “add support for this API version,” and an agent could locate the relevant modules, update the implementation, modify tests, run the test suite, and summarize the result. Human engineers still typically decide whether the change is correct and safe, but they spend less time carrying out every intermediate step.\n\n## Adoption is widespread—but autonomy remains limited\n\nAI-assisted development has become common across the industry. Surveys in 2024 found that roughly three-quarters of software professionals were using or planning to use AI tools, with many reporting regular use for development work.\n\nThe most common applications include:\n\n- Code generation\n- Code search and explanation\n- Test creation\n- Documentation\n- Debugging\n- Refactoring\n\nUse is more cautious when an agent can affect production systems, sensitive data, or security-critical code. Most organizations continue to use approval gates rather than giving agents unrestricted access to deployment systems.\n\nIn practice, the prevailing model is **supervised autonomy**:\n\n1. The agent performs a task.\n2. Automated checks evaluate the result.\n3. A developer reviews the changes.\n4. A human approves, modifies, or rejects them.\n\nFully autonomous software delivery remains the exception rather than the norm.\n\n## Productivity gains are real—but highly variable\n\nAI agents can produce impressive gains on bounded, well-specified tasks. Developers often report faster work in areas such as:\n\n- Boilerplate implementation\n- Unit-test generation\n- API integration\n- Repository exploration\n- Error diagnosis\n- Documentation\n- Small bug fixes\n- Dependency updates\n\nA widely cited GitHub Copilot study found that developers completed a particular coding task approximately 55.8% faster when using the tool. However, that experiment involved an earlier, autocomplete-oriented system and a specific task—not the full complexity of modern software development.\n\nOther industry estimates have suggested potential productivity increases of 20–30% across activities such as coding, testing, documentation, and maintenance. These figures represent potential or task-level improvements, not guaranteed gains for every team.\n\n### Why results differ\n\nAI assistance is most effective when:\n\n- Requirements are explicit\n- The task is local and repetitive\n- Good examples already exist\n- Tests are comprehensive\n- The agent can access the relevant repository context\n- Feedback from tools such as CI is fast and reliable\n\nBenefits decline when work involves:\n\n- Ambiguous requirements\n- Complex business rules\n- Poorly documented systems\n- Cross-service changes\n- Performance constraints\n- Security-sensitive decisions\n- Architectural trade-offs\n\nA 2025 randomized study by METR offered an important counterpoint. It found that experienced open-source developers using contemporary AI tools took approximately 19% longer on selected tasks, even though they expected the tools to make them faster.\n\nThe lesson is not that AI is ineffective. Rather, local speed does not automatically translate into faster end-to-end delivery. Reviewing, correcting, testing, and coordinating AI-generated changes can offset the time saved during implementation.\n\n## The bottleneck is shifting from coding to validation\n\nAs agents generate code more quickly, teams face a new constraint: verifying that the code is correct.\n\nAI-generated changes can create:\n\n- Larger pull requests\n- More frequent incremental changes\n- Additional review work\n- Greater demand for automated testing\n- More “almost correct” implementations\n- New forms of technical debt\n\nDevelopers may spend less time typing code but more time asking:\n\n- Does this actually meet the requirement?\n- What assumptions did the agent make?\n- What cases are missing from the tests?\n- Could this create a security or performance problem?\n- Does the change fit the architecture?\n- What happens in production?\n\nThis makes engineering judgment more valuable, not less. Developers increasingly act as:\n\n- Specification writers\n- Test designers\n- Reviewers\n- System integrators\n- Agent supervisors\n- Risk owners\n\nWhen code generation becomes cheap, knowing what should be built—and recognizing when an implementation is wrong—becomes a larger part of the job.\n\n## Software quality is improving in some areas and deteriorating in others\n\nAI agents can improve quality when they are used to expand test coverage, standardize repetitive work, and identify defects. Common benefits include:\n\n- More unit tests\n- Faster defect diagnosis\n- Better documentation coverage\n- Automated lint and static-analysis fixes\n- More consistent refactoring\n- Faster legacy-system modernization\n\nBut generated code can also introduce serious problems:\n\n- Hallucinated APIs or library behavior\n- Incorrect assumptions about business rules\n- Tests that merely reproduce the implementation\n- Overfitting to visible test cases\n- Unnecessary abstractions\n- Security vulnerabilities\n- Performance regressions\n- Inconsistent changes across a large codebase\n\nAI-generated code may compile and pass existing tests while still being conceptually wrong. This is particularly likely when requirements are implicit or the test suite is weak.\n\nThe quality of an agent’s output depends heavily on the quality of the environment around it. A well-tested, clearly documented repository gives the agent useful constraints. A poorly structured codebase gives it room to guess.\n\n## Better repositories produce better AI results\n\nAI agents perform more reliably in codebases with:\n\n- Clear build and deployment instructions\n- Standard project structures\n- Strong automated tests\n- Explicit architecture documentation\n- Well-written issue descriptions\n- Typed interfaces\n- Small, composable modules\n- Reliable continuous integration\n- Clear ownership metadata\n- Machine-readable configuration\n\nThis creates a new incentive for organizations to treat documentation, testing, and developer tooling as productivity infrastructure.\n\nFor years, teams have sometimes viewed internal documentation and test coverage as overhead. In an agent-assisted environment, these assets become part of the interface between humans and machines. They help agents understand what the system does, what must not change, and how to verify their work.\n\n## Benchmarks show progress—but not full autonomy\n\nSoftware-engineering benchmarks such as SWE-bench have shown rapid improvements in AI systems’ ability to resolve real-world GitHub issues. Leading systems have reported solving more than half of selected issues, with some configurations exceeding 70% on particular SWE-bench Verified evaluations.\n\nThese results are significant, but benchmark performance should not be confused with production-ready autonomy.\n\nBenchmark results vary according to:\n\n- The model\n- The agent framework\n- Available tools\n- Prompting and context\n- Test execution\n- Benchmark version\n- Evaluation methodology\n\nReal software development involves much more than making tests pass. Engineers must also consider:\n\n- Security\n- Maintainability\n- Operational behavior\n- Backward compatibility\n- Product priorities\n- Communication with stakeholders\n- Incident response\n- Long-term architectural consequences\n\nBenchmarks demonstrate that agents can solve many constrained software tasks. They do not show that agents can independently manage a large, unfamiliar production system over months or years.\n\n## Security risks expand with agent capabilities\n\nAgents create greater security risks than simple code-completion tools because they can often execute commands, access repositories, modify configuration, and interact with external services.\n\nKey risks include:\n\n- Vulnerable generated code\n- Exposure of source code, credentials, or customer data\n- Prompt injection through source files, issues, or web content\n- Excessive permissions\n- Unreviewed changes to infrastructure and CI pipelines\n- Insecure dependency recommendations\n- Weak secret handling\n- Limited visibility into why an agent made a change\n\nA malicious instruction hidden in a repository file, issue description, or dependency could potentially influence an agent’s behavior. The more tools and permissions an agent has, the greater the potential impact of an error or attack.\n\nOrganizations using agents should consider:\n\n- Least-privilege access\n- Sandboxed execution\n- Secret isolation\n- Restricted network access\n- Mandatory tests and security scans\n- Detailed audit logs\n- Human approval for production-impacting actions\n- Separate permissions for reading, writing, merging, and deploying\n\nAgentic development should be treated as both a productivity initiative and a security-sensitive systems-integration project.\n\n## Junior developers face a changing learning curve\n\nAI can automate many tasks traditionally assigned to junior engineers:\n\n- Basic bug fixes\n- CRUD functionality\n- Boilerplate code\n- Simple tests\n- Documentation updates\n- Straightforward integrations\n\nThat creates an important tension. These tasks may be routine, but they also provide valuable practice. If agents perform too much entry-level work, junior developers may get fewer opportunities to learn debugging, system behavior, and software design through direct experience.\n\nNew developers will need structured opportunities to build skills in:\n\n- Requirements analysis\n- Testing and validation\n- Debugging from first principles\n- Code review\n- Security\n- System design\n- Production operations\n- Evaluating AI output\n\nAI may increase the productivity gap between developers who can critically assess generated code and those who simply accept it. Knowing how to prompt an agent is useful; knowing when its answer is wrong is more important.\n\n## Engineering metrics need to change\n\nWhen AI can generate code rapidly, traditional measures such as lines of code, commits, and tickets completed become even less meaningful.\n\nOrganizations should focus more on outcomes and delivery health, including:\n\n- Lead time for changes\n- Review latency\n- Change failure rate\n- Defect escape rate\n- Mean time to recovery\n- Rework percentage\n- Test effectiveness\n- Security findings\n- Customer-impacting incidents\n- Time from issue definition to validated release\n\nAn agent may produce hundreds of lines of code in minutes, but that does not mean the team delivered more value. The meaningful question is whether the software is correct, maintainable, secure, and useful to customers.\n\n## Where AI agents are creating the most value\n\nIn 2025, the strongest use cases tend to involve routine or maintenance-heavy work:\n\n- Legacy modernization\n- Test generation\n- Dependency upgrades\n- Framework migrations\n- Internal tools\n- Data-transformation scripts\n- API integrations\n- Documentation\n- Incident triage\n- Small bug fixes\n- Code search and explanation\n\nAgents are less reliable for:\n\n- Novel architecture\n- Safety-critical systems\n- Complex distributed-system changes\n- Poorly specified requirements\n- High-stakes security controls\n- Long-running projects with shifting goals\n\nThis suggests that the near-term economic impact will likely be uneven. AI may make more maintenance work financially practical, accelerate low-priority backlog items, and reduce the number of engineering hours required for routine features.\n\nAt the same time, organizations may place greater demand on senior engineers, technical leads, and specialists who can define requirements, assess risk, and guide system-level decisions.\n\nThere is not yet strong evidence that AI agents caused broad software-engineering employment declines in 2025. Hiring and restructuring decisions remain influenced by many factors, including economic conditions, outsourcing, and changes in product strategy.\n\n## The central trade-off\n\nAI agents are making software production faster and cheaper in specific situations. They are not eliminating the need for engineering expertise.\n\nThe central trade-off is:\n\n> **Code production is becoming cheaper and faster, while specification, validation, security, and architectural judgment are becoming more important.**\n\nThe organizations most likely to benefit will not be those that simply give agents more access.

Determine whether the product is an FDA-regulated medical device\n\nFDA classification depends on the product’s intended use—not simply whether it uses AI.\n\n### Likely FDA considerations\n\n- **Software as a Medical Device (SaMD):** Software that analyzes medical images, symptoms, lab results, or other health information to diagnose, screen, monitor, or guide treatment may be regulated.\n- **Clinical Decision Support (CDS):** Some clinician-facing tools may qualify for statutory non-device CDS treatment, but the exemption is narrow. The clinician generally must be able to independently review the basis for the recommendation and not rely solely on the software.\n- **General wellness or administrative tools:** These may fall outside FDA device regulation if they make only low-risk claims and do not diagnose, prevent, or treat disease.\n\n### Likely FDA pathways\n\nDepending on risk and predicate devices, the product may require:\n\n- **510(k) clearance** if substantially equivalent to a legally marketed predicate.\n- **De Novo classification** for novel, moderate-risk devices without a suitable predicate.\n- **Premarket Approval (PMA)** for high-risk devices.\n- **Investigational Device Exemption (IDE)** if clinical investigation is needed before commercialization.\n- FDA authorization for certain updates or new indications.\n\nAvoid marketing claims such as “diagnoses,” “detects cancer,” or “rules out stroke” until the applicable regulatory pathway and evidence are established.\n\n## 2. Establish intended use and risk classification\n\nDocument:\n\n- Target condition and patient population.\n- Intended users: clinicians, patients, caregivers, or payors.\n- Clinical setting and workflow.\n- Inputs used, including imaging, EHR data, wearables, or genomic data.\n- Output type: probability, recommendation, diagnosis, triage, or treatment guidance.\n- Whether the output is advisory or determinative.\n- Consequences of false positives, false negatives, delay, or inappropriate treatment.\n- Required human review and override procedures.\n\nA formal risk-management process should address hazards such as automation bias, data drift, model failure, inappropriate use outside the validated population, and inability to explain or challenge outputs.\n\n## 3. Build clinical and algorithmic validation evidence\n\nYou should be able to substantiate performance for the actual intended-use population and deployment environment.\n\nRecommended evidence includes:\n\n- Retrospective and prospective validation, as appropriate.\n- Representative demographic and clinical datasets.\n- Sensitivity, specificity, PPV, NPV, calibration, and relevant clinical utility measures.\n- Performance comparisons against accepted clinical standards.\n- Subgroup analysis for race, ethnicity, sex, age, disability, language, socioeconomic status, and relevant comorbidities.\n- Testing across equipment vendors, sites, geographies, and care settings.\n- Evaluation of performance degradation, data drift, and out-of-distribution cases.\n- Human-factors and usability testing.\n- A documented clinical evaluation and statistical analysis plan.\n\nDo not rely solely on overall accuracy if performance differs materially across patient groups.\n\n## 4. Quality-management and AI lifecycle controls\n\nFDA-regulated manufacturers should implement a quality system covering:\n\n- Design controls and design history.\n- Requirements traceability.\n- Verification and validation.\n- Change control.\n- Complaint handling and corrective actions.\n- Supplier and cloud-service oversight.\n- Model versioning and reproducibility.\n- Data and labeling governance.\n- Post-market monitoring.\n\nFDA’s **Quality Management System Regulation (QMSR)** incorporates ISO 13485 concepts; organizations should confirm the applicable effective requirements and transition timelines.\n\nFor AI/ML systems, maintain:\n\n- Training-data provenance and permissions.\n- Dataset versioning.\n- Model cards or equivalent technical documentation.\n- Performance thresholds and release criteria.\n- Monitoring for drift and bias.\n- A documented process for retraining and rollback.\n- A predetermined change-control plan, potentially including an FDA **Predetermined Change Control Plan (PCCP)** where appropriate.\n- Clear disclosure of model limitations and intended operating conditions.\n\nRelevant industry frameworks include:\n\n- ISO 13485 — medical-device quality management.\n- ISO 14971 — medical-device risk management.\n- IEC 62304 — medical-device software lifecycle processes.\n- IEC 62366 — usability engineering.\n- ISO/IEC 27001 — information-security management.\n- NIST AI Risk Management Framework.\n- FDA Good Machine Learning Practice principles.\n\n## 5. HIPAA and health-data privacy\n\nIf the company is a covered entity or business associate, HIPAA obligations generally include:\n\n- Privacy Rule compliance.\n- Security Rule administrative, physical, and technical safeguards.\n- Breach Notification Rule compliance.\n- Business Associate Agreements with covered entities and relevant vendors.\n- Minimum-necessary access and use.\n- Role-based access controls and audit logs.\n- Encryption in transit and at rest.\n- Identity verification and authentication.\n- Retention and deletion controls.\n- Policies for secondary use of data and model training.\n\nImportant distinctions:\n\n- **De-identified data** may fall outside HIPAA, but the de-identification method must meet HIPAA’s Safe Harbor or Expert Determination standard.\n- A **limited data set** generally requires a data-use agreement.\n- Patient authorization may be required for uses not otherwise permitted by HIPAA, particularly commercial model training or unrelated secondary uses.\n\nHIPAA does not preempt stricter state privacy laws.\n\n## 6. State and non-HIPAA privacy laws\n\nIf the product collects data directly from consumers, HIPAA may not apply to all data. Review:\n\n- State comprehensive privacy laws, including California’s CCPA/CPRA and comparable laws in other states.\n- California’s Confidentiality of Medical Information Act.\n- Washington’s **My Health My Data Act**, particularly for consumer health data.\n- State breach-notification laws.\n- Genetic and biometric privacy laws.\n- Mental-health, reproductive-health, HIV, substance-use, and other specially protected data laws.\n- Consent requirements for recording conversations or collecting biometric information.\n\nThe FTC may enforce privacy representations and misuse of health information even when HIPAA does not apply. The **FTC Health Breach Notification Rule** may apply to certain health apps and vendors outside HIPAA.\n\nPrivacy notices should accurately describe:\n\n- What data is collected.\n- Why it is collected.\n- Whether data is used to train or improve models.\n- Whether data is shared with healthcare providers, cloud vendors, advertisers, or other parties.\n- Retention periods.\n- Consumer rights and deletion processes.\n- Automated decision-making and profiling, where applicable.\n\nAvoid using health data for advertising or unrelated analytics without a well-supported legal basis and clear disclosure.\n\n## 7. Cybersecurity requirements\n\nHealthcare diagnostic tools are high-value targets and should have a formal security program covering:\n\n- Threat modeling and secure software development.\n- Secure authentication and authorization.\n- Encryption and key management.\n- Network segmentation.\n- Vulnerability scanning and penetration testing.\n- Dependency and open-source software management.\n- Software bills of materials (SBOMs).\n- Secure update and patch mechanisms.\n- Logging, monitoring, and incident response.\n- Backup, disaster recovery, and business continuity.\n- Ransomware and supply-chain controls.\n- Secure APIs and EHR integrations.\n- Protection against prompt injection or data poisoning if generative AI is used.\n\nFDA cybersecurity requirements may apply to cyber devices, including requirements related to vulnerability management, coordinated vulnerability disclosure, and post-market processes. HIPAA Security Rule controls may also apply.\n\n## 8. Clinical workflow, human oversight, and safety\n\nEstablish clear operating procedures for:\n\n- Who reviews the output.\n- Whether the result is advisory or actionable.\n- How urgent findings are escalated.\n- How clinicians override or disregard the model.\n- What happens when data is missing or outside the validated range.\n- How patients are informed of limitations.\n- How adverse events and near misses are reported.\n- How the tool integrates with the EHR without creating unsafe alert fatigue.\n\nThe product should not imply that it replaces a qualified clinician unless that level of autonomy is specifically validated and authorized.\n\n## 9. Marketing, advertising, and consumer-protection compliance\n\nAll promotional claims must be supported by competent and reliable evidence and must align with the authorized or legally permitted intended use.\n\nAvoid:\n\n- Unsupported superiority claims.\n- “Clinically proven” claims without appropriate evidence.\n- Claims based only on laboratory or retrospective testing.\n- Omitting important limitations.\n- Testimonials suggesting guaranteed diagnostic accuracy.\n- Claims that the product eliminates the need for medical professionals.\n- Selective reporting of favorable subgroup results.\n\nFDA, FTC, state attorneys general, and private litigants may scrutinize misleading claims. User interfaces and sales materials should consistently communicate uncertainty, limitations, and appropriate reliance.\n\n## 10. Other potentially applicable requirements\n\nDepending on the product, review:\n\n- **CLIA:** If the system performs or supports laboratory testing, including certain diagnostic workflows.\n- **Laboratory-developed test rules:** If tied to a laboratory’s own test service.\n- **ONC information-blocking and interoperability rules:** If integrated with certified health IT or exchanging electronic health information.\n- **State professional-licensing laws:** Especially if the company provides clinical services or directly interprets results.\n- **Prescribing and telehealth laws:** If recommendations lead to treatment or prescriptions.\n- **Medicare, Medicaid, and payer rules:** If claims are submitted or reimbursement is sought.\n- **Accessibility laws:** Section 1557, the ADA, and applicable state requirements.\n- **Children’s privacy rules:** COPPA and state children’s privacy requirements if minors are users or subjects.\n- **Human-subjects protections:** IRB review, informed consent, and 21 CFR Parts 50 and 56 when conducting regulated clinical research.\n\n## Practical launch gates\n\nBefore launch, the company should have:\n\n1. A documented intended-use statement and FDA regulatory assessment.\n2. A classification and premarket strategy.\n3. Clinical validation and subgroup performance results.\n4. A quality-management and risk-management system.\n5. Privacy impact and data-protection assessments.\n6. HIPAA role analysis and Business Associate Agreements where applicable.\n7. State privacy and health-data compliance review.\n8. Cybersecurity testing, SBOM, incident-response, and vulnerability-disclosure processes.\n9. Controlled model-release and change-management procedures.\n10. Clinician-facing labeling, limitations, and human-oversight procedures.\n11. A complaint, adverse-event, recall, and post-market monitoring plan.\n12. Legal review of all website, sales, investor, and clinical claims.\n\nThe most important first step is to define precisely **what the tool claims to do, who uses it, and how its output affects patient care**.

Market overview\n\nThe US is the most attractive market for AI diagnostics because it combines:\n\n- High healthcare spending and diagnostic volumes\n- Strong concentration of health systems, labs, and specialist groups\n- Large unmet demand for faster, lower-cost diagnosis\n- Mature reimbursement and health IT infrastructure\n- Significant venture and strategic investment in healthcare AI\n\nHowever, the market is highly regulated and adoption depends on clinical evidence, workflow integration, reimbursement, and provider trust—not just model accuracy.\n\n### Market size\n\nMarket estimates vary substantially depending on the definition of “AI diagnostics.”\n\n| Market layer | Approximate US opportunity | Comments |\n|---|---:|---|\n| US healthcare diagnostics market | Hundreds of billions of dollars annually | Includes imaging, laboratory testing, pathology, cardiology, and other diagnostics |\n| US medical imaging market | Tens of billions annually | Includes radiology, cardiology, pathology, and related services |\n| Global AI-in-healthcare market | Tens of billions today, with high double-digit growth | Includes diagnostics, drug discovery, administrative tools, and clinical decision support |\n| US AI diagnostic software segment | Several billion dollars in current annual opportunity | Smaller than total diagnostics, but growing rapidly |\n| Near-term addressable market for a focused product | Roughly $100M–$1B+ | Depends on disease area, customer type, reimbursement, and deployment model |\n\nA focused startup should not initially market against the entire diagnostics industry. A more realistic initial serviceable obtainable market might be a specific workflow, such as:\n\n- AI-assisted radiology triage\n- Lung nodule or breast cancer detection\n- Diabetic retinopathy screening\n- Sepsis or deterioration prediction\n- Digital pathology\n- Cardiac imaging\n- Point-of-care infectious disease diagnosis\n- Clinical decision support for rare diseases\n\nFor example, a tool priced at $5–$20 per study and deployed across 100 hospitals processing 50,000 relevant studies per hospital annually could represent approximately $25M–$100M in annual recurring revenue, depending on utilization and pricing.\n\n---\n\n## 2. Growth trends\n\n### A. Increasing clinical labor shortages\n\nHospitals face shortages of radiologists, pathologists, laboratory personnel, and specialist clinicians. AI is increasingly positioned as a capacity and productivity tool rather than a complete replacement for clinicians.\n\nThe strongest commercial case is often:\n\n- Reduce turnaround time\n- Prioritize urgent cases\n- Improve throughput\n- Reduce missed findings\n- Standardize quality across sites\n- Support lower-cost care settings\n\n### B. Shift from standalone tools to workflow platforms\n\nHospitals are becoming less willing to purchase numerous independent AI tools that require separate logins and integrations. Demand is moving toward:\n\n- Unified AI marketplaces\n- Enterprise imaging platforms\n- EHR-integrated clinical decision support\n- Vendor-neutral deployment infrastructure\n- Tools that manage monitoring, governance, and model performance\n\nIntegration with PACS, RIS, EHRs, laboratory information systems, and existing clinical workflows is becoming a major competitive differentiator.\n\n### C. Evidence-based procurement\n\nHealthcare buyers increasingly expect:\n\n- Peer-reviewed validation\n- Prospective or real-world evidence\n- Performance across diverse populations\n- Clear measures of clinical and financial impact\n- Explainability and auditability\n- Evidence that the tool improves—not merely predicts—clinical outcomes\n\nTechnical accuracy alone is insufficient. Buyers want proof of reduced length of stay, improved sensitivity, fewer unnecessary tests, faster treatment, or higher clinician productivity.\n\n### D. Movement toward reimbursement and value-based care\n\nFee-for-service reimbursement can support AI when it improves billable throughput or enables additional testing. Value-based care creates opportunities where AI can reduce:\n\n- Avoidable admissions\n- Unnecessary diagnostic procedures\n- Readmissions\n- Delayed diagnoses\n- Expensive downstream treatment\n\nTools that create measurable savings for payers or accountable care organizations may have a broader economic buyer than tools sold only to individual clinicians.\n\n### E. Expansion beyond hospitals\n\nPotential customers increasingly include:\n\n- Independent physician groups\n- Ambulatory surgery centers\n- Urgent care networks\n- Retail clinics\n- National laboratories\n- Telehealth providers\n- Employer health programs\n- Health plans\n- Specialty pharmacy and disease-management companies\n\nOutpatient and decentralized care settings may offer faster sales cycles than major academic hospitals, although they can have lower budgets and less technical infrastructure.\n\n### F. Generative AI and multimodal diagnostics\n\nLarge language models and multimodal systems are expanding use cases involving:\n\n- Summarizing diagnostic reports\n- Combining imaging, labs, notes, and patient history\n- Generating draft clinical documentation\n- Supporting differential diagnosis\n- Explaining findings to clinicians or patients\n\nThese applications also face heightened concerns regarding hallucination, liability, privacy, and validation. The safest early positioning is generally clinician-supportive rather than autonomous diagnosis.\n\n---\n\n## 3. Competitive landscape\n\nCompetition comes from several categories.\n\n### A. Established healthcare technology companies\n\nLarge vendors have distribution, integration capabilities, and existing hospital relationships. Relevant categories include:\n\n- EHR vendors such as Epic, Oracle Health, and MEDITECH\n- Imaging and informatics vendors such as GE HealthCare, Siemens Healthineers, Philips, and Canon Medical\n- Laboratory and diagnostics companies such as Roche, Abbott, Danaher, and Quest Diagnostics\n- Cloud platforms such as Microsoft Azure, Google Cloud, and AWS\n- Enterprise analytics and clinical software companies\n\nThese firms may build internally, partner with startups, or acquire successful products.\n\n### B. AI-native diagnostic companies\n\nRepresentative areas include:\n\n- Radiology AI: Aidoc, Viz.ai, RapidAI, Lunit, and Qure.ai\n- Digital pathology: PathAI, Paige, Ibex, and related vendors\n- Ophthalmology: Digital Diagnostics and EyeArt-type solutions\n- Cardiology and ECG: Eko and other algorithm developers\n- Clinical decision support: numerous specialized startups\n- Imaging workflow and triage: a large and increasingly crowded field\n\nThe competitive environment varies substantially by specialty. Radiology and stroke detection are relatively crowded, while certain rare diseases, pathology sub-specialties, and decentralized testing applications may offer more whitespace.\n\n### C. Internal health-system development\n\nLarge academic medical centers and integrated delivery networks increasingly build or fine-tune their own models. A startup must demonstrate advantages in:\n\n- Generalizability\n- Deployment speed\n- Regulatory readiness\n- Maintenance and monitoring\n- Multi-site validation\n- Total cost of ownership\n\n### D. General-purpose AI platforms\n\nCloud and foundation-model companies may provide underlying capabilities for image analysis, clinical language processing, and multimodal reasoning. Startups can still win by owning:\n\n- The regulated product layer\n- Specialty-specific validation\n- Workflow integration\n- Clinical liability controls\n- Distribution and customer relationships\n\n---\n\n## 4. Regulatory and compliance environment\n\nRegulatory strategy should be established before product development is finalized.\n\n### FDA considerations\n\nMost diagnostic software that provides patient-specific clinical information may be regulated as Software as a Medical Device. Possible pathways include:\n\n- **510(k):** Requires substantial equivalence to a legally marketed predicate\n- **De novo:** For novel moderate-risk devices without a suitable predicate\n- **PMA:** For high-risk products requiring extensive clinical evidence\n- **Enforcement discretion or non-device CDS categories:** Potentially applicable to limited, transparent, clinician-directed functionality\n\nThe appropriate pathway depends on intended use, clinical risk, degree of autonomy, and whether the software drives diagnosis or treatment.\n\nThe FDA is also paying increasing attention to:\n\n- Adaptive or continuously learning algorithms\n- Predetermined change-control plans\n- Bias and subgroup performance\n- Cybersecurity\n- Post-market monitoring\n- Transparency and human oversight\n\n### Other obligations\n\nDepending on the product, the company may also need to address:\n\n- HIPAA and business associate agreements\n- SOC 2 and healthcare security requirements\n- HITECH and state privacy laws\n- CLIA and potentially CAP accreditation if operating a laboratory\n- State professional licensing requirements\n- Information blocking and interoperability standards\n- Clinical trial and institutional review board requirements\n- Product liability and medical malpractice exposure\n\nIf the product is a laboratory-developed test or directly performs diagnostic testing, the regulatory and operational burden can be materially higher than for clinician-support software.\n\n---\n\n## 5. Business models\n\n### 1. Enterprise software licensing\n\nCommon structures include:\n\n- Annual site license\n- Per-bed pricing\n- Per-study or per-test pricing\n- Usage tiers\n- Multi-year enterprise contracts\n\nThis model works best when the tool integrates into a hospital-wide workflow and has measurable utilization.\n\n### 2. Performance or value-based pricing\n\nPricing can be linked to:\n\n- Diagnoses detected\n- Cases prioritized\n- Tests avoided\n- Readmissions reduced\n- Turnaround time improvement\n- Revenue or savings generated\n\nThis can improve customer adoption but creates measurement complexity and sales-cycle friction.\n\n### 3. Payer or risk-bearing organization contracts\n\nThe product can be sold to insurers or accountable care organizations when it reduces total cost of care or improves earlier intervention.\n\n### 4. Diagnostic service or managed-service model\n\nRather than selling software, the company can provide an AI-supported diagnostic service, potentially including:\n\n- Remote interpretation\n- Centralized quality review\n- Specialist escalation\n- Continuous monitoring\n\nThis may generate higher revenue per case but creates more operational and liability responsibilities.\n\n---\n\n## 6. Best initial market opportunities\n\nThe strongest entry opportunities generally share five characteristics:\n\n1. High diagnostic volume \n2. Clear clinical pain point \n3. Expensive or dangerous delays \n4. Existing reimbursement or budget ownership \n5. A measurable return on investment \n\n### Attractive segments\n\n#### Emergency and acute care\nExamples include stroke, pulmonary embolism, intracranial hemorrhage, and pneumothorax. The value proposition is rapid prioritization and time-to-treatment improvement.\n\n#### Radiology productivity\nTools that reduce reporting time, automate measurements, or identify urgent studies can support a clear labor and throughput case. Competition is intense, so differentiation is essential.\n\n#### Digital pathology\nPathology faces workforce shortages and growing testing volumes. AI can support tumor detection, grading, biomarker quantification, and workflow prioritization. Validation and integration requirements are substantial.\n\n#### Eye disease screening\nDiabetic retinopathy and other ophthalmic screening applications are attractive because they can enable care in primary-care and retail settings. Autonomous or semi-autonomous claims increase regulatory complexity.\n\n#### Cardiology\nECG, echocardiography, and cardiac imaging tools may benefit from high volumes and the need for earlier risk stratification.\n\n#### Specialty and rare disease diagnostics\nThese markets may be smaller but can have less competition, high diagnostic costs, and significant value from reducing the diagnostic odyssey.\n\n#### Decentralized and rural care\nAI can extend specialist capabilities to community hospitals, urgent care centers, and underserved regions. This is particularly attractive where specialist access is limited.\n\n---\n\n## 7. Go-to-market strategy\n\n### Recommended beachhead\n\nStart with one clinical indication and one buyer persona rather than positioning the product as a general diagnostic AI platform.\n\nPotential beachhead customers:\n\n- Specialty physician groups\n- Community hospitals with limited specialist coverage\n- Regional health systems\n- National imaging or laboratory networks\n- High-volume outpatient providers\n\nLarge academic medical centers offer strong credibility but often have long procurement cycles and internal innovation programs. A regional health system may provide faster commercialization and more meaningful deployment data.\n\n### Key commercial steps\n\n1. Define a narrow intended use and regulatory classification.\n2. Conduct retrospective validation using representative US data.\n3. Demonstrate performance by race, sex, age, geography, scanner, site, and disease prevalence.\n4. Run a prospective or silent-mode clinical study.\n5. Integrate into the customer’s existing workflow.\n6. Quantify financial and clinical outcomes.\n7. Use early deployments to generate peer-reviewed evidence and reference customers.\n8. Expand from one use case into adjacent indications only after adoption is established.\n\n### Sales cycle expectations\n\nEnterprise healthcare sales often take:\n\n- 6–18 months for major health systems\n- 3–9 months for smaller provider groups\n- Longer when new reimbursement, clinical protocols, or cybersecurity reviews are required\n\nThe economic buyer may be the chief medical officer, department chair, radiology or pathology leader, CIO, innovation office, or CFO—not necessarily the end clinician.\n\n---\n\n## 8. Major risks\n\n### Clinical and regulatory risk\n\nA false negative can delay treatment; a false positive can create unnecessary testing and anxiety. Liability concerns may limit autonomous use.\n\n### Bias and generalizability\n\nPerformance can decline across:\n\n- Different demographic groups\n- Different equipment manufacturers\n- Community versus academic hospitals\n- Different prevalence levels\n- International versus US populations\n\n### Workflow failure\n\nEven highly accurate tools may fail commercially if they create alerts, require extra clicks, or disrupt existing practice.\n\n### Reimbursement uncertainty\n\nMany tools do not have a dedicated payment code. Customers may need to justify the purchase through productivity gains, quality incentives, or avoided costs.\n\n### Procurement and integration friction\n\nSecurity reviews, data-use agreements, PACS/EHR integration, and IT implementation can delay deployment.\n\n### Platform competition\n\nEHR, imaging, laboratory, and cloud vendors may absorb the functionality into broader platforms or bundle it at low incremental cost.\n\n### Evidence gap\n\nA model may perform well retrospectively but fail to improve real-world outcomes. Prospective evaluation is increasingly important.\n\n---\n\n## 9. Strategic recommendations\n\n### Position around outcomes, not AI\n\nThe strongest messaging is typically:\n\n- “Reduce critical-result turnaround time by X%”\n- “Increase specialist capacity by X cases per day”\n- “Improve sensitivity without increasing unnecessary testing”\n- “Enable screening in primary-care settings”\n- “Reduce avoidable transfers or admissions”\n\nAvoid leading with model architecture or generic claims of intelligence.\n\n### Build for clinical oversight\n\nInitially emphasize:\n\n- Clinician-in-the-loop review\n- Clear confidence indicators\n- Explainable findings\n- Audit trails\n- Override and feedback mechanisms\n- Robust monitoring for model drift\n\n### Choose a narrow regulatory claim\n\nA narrowly defined indication may achieve approval and commercial adoption faster than a broad “AI diagnostic assistant” claim.\n\n### Secure distribution partners\n\nPotential partners include:\n\n- PACS and EHR vendors\n- Imaging equipment manufacturers\n- National laboratories\n- Telehealth networks\n- Health plans\n- Clinical service organizations\n- Cloud marketplaces\n\nPartnerships can shorten integration and sales cycles but may reduce margins and control.\n\n### Prove economic value early\n\nBefore scaling, measure:\n\n- Time saved per case\n- Incremental diagnostic volume\n- Reduced report turnaround\n- Changes in downstream testing\n- Clinical outcomes\n- Revenue generated\n- Cost avoided\n- User adoption and override rates\n\n---\n\n## 10. Overall market assessment\n\nThe US market for AI-powered diagnostics is large and growing, but it is not an easy software market.

The most important early decision is how the product is positioned:\n\n- **Administrative or wellness tool:** May face lighter regulation, but claims must remain limited and truthful.\n- **Clinical decision support:** May be subject to FDA oversight depending on functionality and whether clinicians can independently review the basis for recommendations.\n- **Diagnostic device or software as a medical device (SaMD):** Likely requires FDA classification, quality-system controls, clinical validation, and potentially premarket authorization.\n- **Autonomous diagnosis or treatment recommendation:** Generally presents the highest FDA, malpractice, patient-safety, and liability exposure.\n\nThe company should avoid treating regulatory clearance as the only launch milestone. It must also establish evidence, post-market monitoring, cybersecurity, reimbursement, workflow integration, and a defensible liability model.\n\n---\n\n## 1. Regulatory and legal risks\n\n### 1.1 FDA classification and authorization\n\n**Risk:** The product may be considered a medical device under the Federal Food, Drug, and Cosmetic Act if it is intended to diagnose, detect, prevent, or guide treatment of disease.\n\nPotential pathways include:\n\n- **510(k) clearance** if a suitable predicate exists.\n- **De Novo classification** for novel, lower-to-moderate-risk devices without a predicate.\n- **Premarket Approval (PMA)** for high-risk devices requiring substantial clinical evidence.\n- **Breakthrough Device designation** for certain technologies addressing serious conditions, though this does not eliminate evidence requirements.\n\nRisks increase if the product:\n\n- Makes disease-specific diagnostic claims.\n- Recommends treatment or triage.\n- Operates autonomously without clinician review.\n- Interprets images, pathology, ECGs, or other clinical data.\n- Is used in high-acuity settings such as emergency care, oncology, cardiology, or intensive care.\n- Continuously changes through machine learning after deployment.\n\n**Mitigation:**\n\n1. Define the intended use, target population, input data, output, and user precisely.\n2. Obtain an early FDA pre-submission meeting.\n3. Build a regulatory classification analysis before product development is finalized.\n4. Avoid marketing claims that exceed the authorized intended use.\n5. Establish a change-control process for algorithm updates.\n6. Determine whether each model update requires a new submission, a supplement, or can be covered under a predetermined change-control plan.\n\n---\n\n### 1.2 Clinical validation and evidence quality\n\n**Risk:** Technical performance in development data may not translate to real-world clinical performance. FDA reviewers, providers, payers, and plaintiffs may scrutinize:\n\n- Sensitivity and specificity.\n- False-negative and false-positive rates.\n- Performance across demographic and clinical subgroups.\n- External validation across institutions and equipment.\n- Prevalence and spectrum effects.\n- Comparisons with current clinical practice.\n- Clinical utility, not merely statistical accuracy.\n\nA model can have strong area-under-the-curve performance but still be unsafe if it causes inappropriate referrals, delays care, or creates alert fatigue.\n\n**Mitigation:**\n\n- Conduct prospective, multi-site validation studies.\n- Use representative data from different geographies, devices, health systems, and patient populations.\n- Pre-specify endpoints and statistical analysis plans.\n- Evaluate calibration, confidence intervals, and clinically relevant thresholds.\n- Measure clinical workflow outcomes, such as time to diagnosis and downstream testing.\n- Conduct subgroup analyses for race, ethnicity, sex, age, disability, language, comorbidities, and socioeconomic factors.\n- Maintain a complete data provenance and labeling record.\n- Consider independent clinical adjudication and publication of results.\n\n---\n\n### 1.3 HIPAA and health-data privacy\n\n**Risk:** If the company handles protected health information on behalf of providers, health plans, or other covered entities, it may be a HIPAA business associate. Obligations can include:\n\n- Business associate agreements.\n- Privacy and security safeguards.\n- Breach notification.\n- Minimum-necessary access.\n- Audit controls and access logging.\n- Restrictions on secondary use of patient data.\n\nEven if HIPAA does not apply in a particular business model, state privacy laws and contractual obligations may still apply.\n\nRelevant laws may include:\n\n- California Consumer Privacy Act/California Privacy Rights Act.\n- Washington My Health My Data Act.\n- Connecticut, Colorado, Virginia, and other state comprehensive privacy laws.\n- State medical-record confidentiality laws.\n- Federal Trade Commission rules and enforcement relating to deceptive privacy or security practices.\n\n**Mitigation:**\n\n- Map all data flows, processors, storage locations, and data uses.\n- Execute appropriate business associate agreements.\n- Minimize collection and retention.\n- Separate product-improvement data from clinical-care data.\n- Obtain valid consent where required.\n- Implement patient access, deletion, correction, and opt-out processes where applicable.\n- Prohibit use of patient data for model training unless contractually and legally authorized.\n- Use de-identification or limited data sets where feasible.\n- Maintain a documented data-retention and destruction policy.\n\n---\n\n### 1.4 Consumer protection and marketing claims\n\n**Risk:** The FDA, FTC, state attorneys general, and private litigants may challenge claims that are misleading, unsupported, or likely to create unreasonable expectations. High-risk claims include:\n\n- “Diagnoses cancer.”\n- “Eliminates physician error.”\n- “Works for all patients.”\n- “Bias-free.”\n- “Clinically proven” without appropriate evidence.\n- Claims based only on retrospective or internal data.\n- Comparisons with clinicians or competing products without substantiation.\n\n**Mitigation:**\n\n- Conduct legal and clinical review of all marketing materials.\n- Align product claims exactly with the cleared or authorized intended use.\n- Clearly disclose the role of clinicians and known limitations.\n- Maintain evidence files supporting every performance claim.\n- Establish formal approval processes for websites, sales presentations, and customer-facing materials.\n- Monitor distributor and reseller statements.\n\n---\n\n### 1.5 State medical practice, licensing, and liability\n\n**Risk:** State laws may treat automated diagnosis or treatment recommendations as the practice of medicine. Issues may include:\n\n- Whether a physician must supervise or review outputs.\n- Telehealth and remote-practice requirements.\n- Corporate-practice-of-medicine restrictions.\n- Professional licensing across state lines.\n- Rules governing informed consent and patient notification.\n- Malpractice exposure for providers relying on the tool.\n- Product-liability claims against the manufacturer.\n\nA missed diagnosis, inappropriate triage decision, or undocumented model limitation could lead to significant damages.\n\n**Mitigation:**\n\n- Obtain state-by-state legal analysis for intended deployment.\n- Define clinician responsibilities in contracts and user interfaces.\n- Use clear escalation rules and human review for high-risk outputs.\n- Preserve audit logs showing input data, model version, output, confidence, and user actions.\n- Provide warnings that are specific and operational rather than generic disclaimers.\n- Maintain product liability, errors and omissions, cyber, and clinical-trial insurance.\n- Establish an incident-response and patient-notification process.\n\n---\n\n### 1.6 CMS, reimbursement, and billing risks\n\n**Risk:** Clinical adoption may be limited if customers cannot obtain reimbursement. Additional exposure may arise if the tool:\n\n- Encourages inappropriate billing.\n- Is bundled into existing services.\n- Is billed under codes that do not accurately describe the service.\n- Generates documentation used in fraud or abuse.\n- Creates financial incentives affecting referrals or utilization.\n\nPotential issues include Medicare, Medicaid, commercial payer policies, Stark Law, Anti-Kickback Statute, and state equivalents.\n\n**Mitigation:**\n\n- Develop a reimbursement strategy before launch.\n- Obtain coding and coverage advice from qualified experts.\n- Avoid guarantees of reimbursement.\n- Structure pricing and incentives to avoid utilization-based conflicts.\n- Validate economic outcomes such as avoided admissions, reduced testing, or improved care quality.\n- Support customers with compliant documentation and billing guidance.\n\n---\n\n### 1.7 Cybersecurity and critical-infrastructure obligations\n\n**Risk:** Healthcare systems are frequent targets of ransomware, credential theft, supply-chain attacks, and data exfiltration. A compromise could affect patient safety, not merely confidentiality. Risks include:\n\n- Manipulation of model inputs or outputs.\n- Unauthorized model access.\n- Attacks on APIs or cloud infrastructure.\n- Malicious or corrupted training data.\n- Compromised third-party libraries.\n- Denial of service during clinical operations.\n- Inadequate vulnerability disclosure and patching.\n\nFDA cybersecurity expectations for medical devices are increasingly significant, including secure development, threat modeling, vulnerability management, software bills of materials, and post-market processes.\n\n**Mitigation:**\n\n- Implement a secure software development lifecycle.\n- Use threat modeling and security risk assessments.\n- Encrypt data in transit and at rest.\n- Apply strong identity, access, and secrets management.\n- Use network segmentation, immutable backups, and disaster recovery.\n- Maintain a software bill of materials.\n- Conduct penetration testing and independent security assessments.\n- Establish coordinated vulnerability disclosure.\n- Define downtime procedures for continued clinical operations.\n- Test resilience against adversarial inputs and data poisoning.\n\n---\n\n### 1.8 AI-specific regulatory uncertainty\n\n**Risk:** U.S. AI regulation remains fragmented. The company may face overlapping expectations from:\n\n- FDA.\n- FTC.\n- HHS and OCR.\n- State privacy and AI laws.\n- State professional boards.\n- Payers and healthcare accreditation organizations.\n- Procurement requirements of hospitals and public-sector customers.\n\nAdditional issues include algorithmic discrimination, explainability, automated decision-making, and patient notice.\n\n**Mitigation:**\n\n- Maintain an AI governance committee with clinical, regulatory, legal, privacy, security, and data-science representation.\n- Create an algorithmic impact assessment for every major use case.\n- Maintain model cards, data sheets, intended-use statements, limitations, and subgroup results.\n- Document human oversight and appeal or override mechanisms.\n- Track federal and state legislative developments.\n- Design for auditability and transparency from the outset.\n\n---\n\n## 2. Technical and operational risks\n\n### 2.1 Dataset bias and limited generalizability\n\n**Risk:** Training data may overrepresent certain hospitals, devices, racial groups, age ranges, or disease severities. Performance can deteriorate when deployed in community hospitals, rural settings, or populations with different disease prevalence.\n\n**Mitigation:**\n\n- Use diverse, multi-institutional datasets.\n- Test across demographic and clinical subgroups.\n- Conduct site-specific validation before deployment.\n- Monitor real-world performance by subgroup.\n- Permit controlled local calibration where appropriate.\n- Do not rely solely on aggregate accuracy metrics.\n\n---\n\n### 2.2 Data quality and label errors\n\n**Risk:** Clinical data can be incomplete, duplicated, delayed, inconsistently coded, or mislabeled. Weak reference standards can produce inflated performance estimates.\n\n**Mitigation:**\n\n- Establish data-quality thresholds and automated validation.\n- Use multiple expert reviewers for high-risk labels.\n- Measure inter-rater agreement.\n- Track missingness and label uncertainty.\n- Prevent patient-level leakage between training and test sets.\n- Maintain data lineage and versioned datasets.\n\n---\n\n### 2.3 Model drift and changing clinical environments\n\n**Risk:** Performance can degrade due to:\n\n- New equipment or imaging protocols.\n- Changes in patient demographics.\n- New diagnostic criteria.\n- Evolving disease prevalence.\n- Different clinical workflows.\n- Changes in coding or documentation practices.\n- Adversarial or unexpected user behavior.\n\n**Mitigation:**\n\n- Implement continuous performance monitoring.\n- Set predefined alert thresholds for drift and subgroup degradation.\n- Use prospective silent-mode testing before activating recommendations.\n- Restrict updates through formal validation and approval gates.\n- Provide rollback capability.\n- Reassess the model after major changes in data, workflow, or clinical guidance.\n\n---\n\n### 2.4 Explainability and clinician trust\n\n**Risk:** Clinicians may not understand why a model generated an output, leading either to inappropriate reliance or rejection of useful recommendations. Generic explanations may be misleading.\n\n**Mitigation:**\n\n- Provide clinically meaningful rationale, not just technical feature importance.\n- Display confidence, uncertainty, missing data, and known limitations.\n- Make the model’s role in the workflow explicit.\n- Keep final clinical responsibility with appropriately licensed professionals where applicable.\n- Monitor override rates and investigate systematic disagreement.\n\n---\n\n### 2.5 Human factors and workflow integration\n\n**Risk:** A technically accurate tool can still harm patients if it creates alert fatigue, interrupts workflow, delays care, or generates ambiguous recommendations. Poor interface design may encourage automation bias.\n\n**Mitigation:**\n\n- Conduct human-factors engineering and usability testing.\n- Map the end-to-end clinical workflow before deployment.\n- Test with physicians, nurses, technicians, and administrative users.\n- Use tiered alerts based on urgency and confidence.\n- Avoid excessive alerts.\n- Define escalation, acknowledgment, and follow-up responsibilities.\n- Measure real-world workflow impact after implementation.\n\n---\n\n### 2.6 Interoperability and reliability\n\n**Risk:** The system may fail because of inconsistent EHR interfaces, outdated data, integration outages, incorrect patient matching, or incompatible formats. A wrong-patient or stale-data error can be particularly serious.\n\n**Mitigation:**\n\n- Support standard interfaces such as FHIR where practical.\n- Validate patient identity and encounter context.\n- Display data timestamps and source systems.\n- Test integrations in realistic environments.\n- Implement monitoring for missing, delayed, or malformed inputs.\n- Provide graceful degradation and downtime workflows.\n- Establish service-level objectives appropriate to clinical criticality.\n\n---\n\n### 2.7 Generative AI and hallucination risk\n\nIf the tool generates explanations, summaries, or recommendations using a large language model, additional risks include:\n\n- Fabricated clinical facts or citations.\n- Inconsistent outputs for similar cases.\n- Prompt injection through clinical notes.\n- Leakage of sensitive information.\n- Overconfident language.\n- Uncontrolled use of external knowledge.\n\n**Mitigation:**\n\n- Limit generative functionality to bounded, validated tasks.\n- Use retrieval from approved clinical sources.\n- Apply output validation and rule-based constraints.\n- Prohibit autonomous diagnosis or treatment recommendations unless specifically validated and authorized.\n- Display source evidence and uncertainty.\n- Log prompts, outputs, model versions, and user actions.\n- Conduct red-team testing for hallucination and prompt injection.\n\n---\n\n## 3. Competitive and commercial threats\n\n### 3.1 Incumbent EHR and medical-device vendors\n\nLarge vendors may integrate comparable capabilities directly into EHRs, imaging platforms, laboratory systems, or devices. Their advantages include:\n\n- Existing hospital relationships.\n- Access to workflow and clinical data.\n- Procurement credibility.\n- Integrated support and contracting.\n- Ability to bundle functionality.\n\n**Mitigation:**\n\n- Focus on a clearly defined high-value clinical problem.\n- Integrate with major EHR and device ecosystems.\n- Build a differentiated evidence base.\n- Offer measurable outcomes rather than generic AI functionality.\n- Pursue channel partnerships and OEM arrangements where appropriate.\n\n---\n\n### 3.2 Rapid commoditization of AI models\n\nFoundation models and generic computer-vision capabilities may reduce technical differentiation. Competitors may copy features or offer lower prices.\n\n**Mitigation:**\n\nBuild defensibility around:\n\n- Proprietary, high-quality clinical datasets.\n- Regulatory clearances and validated intended use.\n- Workflow integration.\n- Longitudinal outcome evidence.\n- Clinical partnerships.\n- Switching costs and customer support.\n- Strong privacy and security posture.\n- Specialized models that perform well in a defined use case.\n\n---\n\n### 3.3 Slow healthcare sales cycles\n\nHospital procurement can take many months or years and may require:\n\n- Security reviews.\n- Clinical committee approval.\n- IT integration.\n- Legal and privacy review.\n- Value analysis.\n- Budget approval.\n- Pilot studies.\n\n**Mitigation:**\n\n- Target early adopters with a clear unmet need.\n- Offer controlled pilots with predefined success metrics.\n- Provide implementation and integration support.\n- Prepare standardized security, privacy, regulatory, and clinical evidence packages.\n- Start with departments where economic value is easy to measure.\n- Develop partnerships with academic medical centers and health systems.\n\n---\n\n### 3.4 Reimbursement and unclear economic value\n\nA product may improve diagnostic accuracy but fail to generate a clear financial return for the buyer. Benefits may accrue to a different party from the one paying for the product.\n\n**Mitigation:**\n\n- Quantify total economic value, including labor savings, reduced length of stay, avoided testing, earlier treatment, and quality incentives.\n- Align pricing with the customer’s budget and value realization.\n- Consider per-use, subscription, enterprise, or outcomes-based pricing carefully.\n- Build evidence for both clinical and operational outcomes.\n\n---\n\n### 3.5 Customer concentration and channel dependency\n\nDependence on one health system, distributor, cloud provider, or EHR platform can create commercial and operational vulnerability.\n\n**Mitigation:**\n\n- Diversify customers and distribution channels.\n- Use contract protections for data access, service levels, termination, and portability.\n- Maintain alternatives for critical cloud and technology suppliers.\n- Avoid exclusive arrangements unless they produce substantial strategic value.\n\n---\n\n## 4.

Recommended mitigation roadmap\n\n### Before development is complete\n\n1. Define a narrow, clinically specific intended use.\n2. Determine likely FDA classification and obtain regulatory advice.\n3. Establish clinical, legal, privacy, cybersecurity, and AI governance.\n4. Create a representative data and validation plan.\n5. Decide whether the product is assistive or autonomous.\n6. Map privacy, security, and data-rights requirements.\n7. Identify reimbursement and buyer economics.\n\n### Before regulatory submission or pilot deployment\n\n1. Complete external and prospective validation where feasible.\n2. Conduct subgroup and bias analysis.\n3. Implement a quality management system, such as one aligned with FDA expectations and ISO 13485 principles.\n4. Complete threat modeling, penetration testing, and software documentation.\n5. Perform human-factors and workflow testing.\n6. Establish version control, audit logs, and update procedures.\n7. Prepare adverse-event, complaint-handling, and recall processes.\n\n### Before broad commercial launch\n\n1. Obtain required FDA authorization or confirm the applicable exemption.\n2. Complete HIPAA, privacy, and contracting controls.\n3. Validate each major EHR and device integration.\n4. Establish monitoring for accuracy, drift, outages, bias, and user overrides.\n5. Train customers and define human oversight responsibilities.\n6. Finalize product-liability and cyber insurance.\n7. Launch initially through a controlled rollout with predefined stop criteria.\n\n### After launch\n\n1. Monitor real-world clinical performance continuously.\n2. Review incidents, complaints, near misses, and subgroup degradation.\n3. Revalidate after significant model, data, workflow, or clinical-guideline changes.\n4. Maintain vulnerability disclosure and patching programs.\n5. Conduct periodic regulatory and privacy audits.\n6. Publish transparent evidence and update limitations as new information emerges.\n\n## Bottom line\n\nThe highest-risk strategy is to launch a broad, autonomous diagnostic product with strong marketing claims but limited external clinical evidence and weak monitoring. A lower-risk path is to begin with a **narrow, clinician-supervised use case**, pursue the appropriate FDA pathway early, validate performance across diverse real-world settings, integrate deeply into clinical workflows, and treat cybersecurity, bias monitoring, and post-market surveillance as core product functions rather than compliance add-ons.", + "metadata" : { + "messageType" : "ASSISTANT" + }, + "toolCalls" : [ ], + "media" : [ ] + }, + "metadata" : { + "finishReason" : "STOP", + "contentFilters" : [ ], + "properties" : { } + } + } ] + } +} diff --git a/llm-recordings/09_human_in_the_loop/1_3af5ba10-975e-42f8-80e0-a9540787735f.json b/llm-recordings/09_human_in_the_loop/1_3af5ba10-975e-42f8-80e0-a9540787735f.json new file mode 100644 index 0000000000..5e4ece9872 --- /dev/null +++ b/llm-recordings/09_human_in_the_loop/1_3af5ba10-975e-42f8-80e0-a9540787735f.json @@ -0,0 +1,99 @@ +{ + "schemaVersion" : 3, + "request" : { + "messages" : [ { + "role" : "system", + "text" : "You are a banking assistant.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Simple APIs. Scalable control.**\n\n### Core promise\n\nThe User Management API gives development teams a secure, flexible foundation for registration, authentication, authorization, session management, and administrative user operations—without requiring them to build identity infrastructure from scratch.\n\n---\n\n## 1. Target audiences\n\n### Primary audiences\n\n- Backend and full-stack developers\n- Engineering managers and technical leads\n- SaaS and platform teams\n- Startup founders building customer-facing products\n- Security and compliance leaders\n- Product teams launching applications with account-based experiences\n\n### Ideal use cases\n\n- SaaS account management\n- B2B applications with multiple roles\n- Customer portals\n- Internal tools and workforce applications\n- Developer platforms\n- Applications requiring secure sessions and administrative controls\n\n### Buyer concerns\n\n- Authentication security and password handling\n- Time required to build and maintain identity features\n- Role-based access control\n- Session revocation and token security\n- Scalability and reliability\n- Auditability and compliance readiness\n- Developer experience and integration speed\n\n---\n\n## 2. Positioning\n\n### Positioning statement\n\nFor engineering teams that need reliable identity capabilities, the User Management API is a developer-friendly REST API that provides secure authentication, role-based authorization, session management, and scalable administration through clear, versioned endpoints.\n\nUnlike a basic login service, it supports the broader user lifecycle—from registration and email verification to password resets, session revocation, role management, and audit events.\n\n### Competitive distinction\n\nEmphasize that the API combines:\n\n- Production-minded security controls\n- Straightforward REST resources\n- Flexible browser and native-client authentication strategies\n- Built-in administrative workflows\n- Clear error responses and validation\n- Pagination, filtering, and versioning for long-term maintainability\n\nAvoid claiming that the API eliminates all security or compliance work. Position it as a strong foundation that helps teams implement identity capabilities consistently.\n\n---\n\n## 3. Key messaging\n\n### Message 1: Secure authentication from day one\n\nSupport modern authentication workflows, including:\n\n- Registration and email verification\n- Argon2id password hashing\n- Password reset flows\n- Short-lived access tokens\n- Rotating refresh tokens\n- Refresh-token reuse detection\n- Session revocation\n- Rate limiting and abuse prevention\n\n**Proof point:** Passwords, tokens, and sensitive security metadata are never exposed through user responses.\n\n### Message 2: Authorization that matches your organization\n\nUse role-based access control for users, support teams, administrators, and security administrators.\n\n**Proof point:** Combine role checks with resource ownership rules so users can manage their own profiles while privileged teams handle administrative operations.\n\n### Message 3: Manage the complete user lifecycle\n\nHandle more than login:\n\n- Create and verify accounts\n- Update profiles\n- Suspend or deactivate users\n- Reset passwords\n- Review active sessions\n- Revoke individual or all sessions\n- Assign roles\n- Record administrative actions\n\n### Message 4: Developer-friendly REST design\n\nIntegrate using predictable HTTP methods, JSON payloads, consistent error formats, and versioned endpoints.\n\n**Proof point:** Cursor-based pagination, filtering, sorting, OpenAPI documentation, and RFC-style problem responses make the API easier to build against and operate.\n\n### Message 5: Security and scale built into the architecture\n\nSupport production operations with:\n\n- Audit events\n- Strong transport and cookie controls\n- Configurable authorization policies\n- API versioning\n- Key rotation support\n- Monitoring and abuse detection hooks\n\n---\n\n## 4.

Developer documentation copy\n\n### Documentation introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6.

Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- Support UTF-8\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Browser applications\n\nUse:\n\n- Short-lived access tokens: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh tokens\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\n### APIs and native clients\n\nUse:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11. Security controls\n\n### Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n### Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n### CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n### Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n## 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n## 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n## 14.

Simple APIs. Scalable control.**\n\n### Core promise\n\nThe User Management API gives development teams a secure, flexible foundation for registration, authentication, authorization, session management, and administrative user operations—without requiring them to build identity infrastructure from scratch.\n\n---\n\n## 1. Target audiences\n\n### Primary audiences\n\n- Backend and full-stack developers\n- Engineering managers and technical leads\n- SaaS and platform teams\n- Startup founders building customer-facing products\n- Security and compliance leaders\n- Product teams launching applications with account-based experiences\n\n### Ideal use cases\n\n- SaaS account management\n- B2B applications with multiple roles\n- Customer portals\n- Internal tools and workforce applications\n- Developer platforms\n- Applications requiring secure sessions and administrative controls\n\n### Buyer concerns\n\n- Authentication security and password handling\n- Time required to build and maintain identity features\n- Role-based access control\n- Session revocation and token security\n- Scalability and reliability\n- Auditability and compliance readiness\n- Developer experience and integration speed\n\n---\n\n## 2. Positioning\n\n### Positioning statement\n\nFor engineering teams that need reliable identity capabilities, the User Management API is a developer-friendly REST API that provides secure authentication, role-based authorization, session management, and scalable administration through clear, versioned endpoints.\n\nUnlike a basic login service, it supports the broader user lifecycle—from registration and email verification to password resets, session revocation, role management, and audit events.\n\n### Competitive distinction\n\nEmphasize that the API combines:\n\n- Production-minded security controls\n- Straightforward REST resources\n- Flexible browser and native-client authentication strategies\n- Built-in administrative workflows\n- Clear error responses and validation\n- Pagination, filtering, and versioning for long-term maintainability\n\nDo not claim that the API eliminates all security or compliance work. Position it as a strong foundation that helps teams implement identity capabilities consistently.\n\n---\n\n## 3. Key messaging\n\n### Secure authentication from day one\n\nSupport:\n\n- Registration and email verification\n- Argon2id password hashing\n- Password reset flows\n- Short-lived access tokens\n- Rotating refresh tokens\n- Refresh-token reuse detection\n- Session revocation\n- Rate limiting and abuse prevention\n\n**Proof point:** Passwords, tokens, and sensitive security metadata are never exposed through user responses.\n\n### Authorization that matches your organization\n\nUse role-based access control for users, support teams, administrators, and security administrators.\n\n**Proof point:** Combine role checks with resource ownership rules so users can manage their own profiles while privileged teams handle administrative operations.\n\n### Manage the complete user lifecycle\n\nHandle more than login:\n\n- Create and verify accounts\n- Update profiles\n- Suspend or deactivate users\n- Reset passwords\n- Review active sessions\n- Revoke individual or all sessions\n- Assign roles\n- Record administrative actions\n\n### Developer-friendly REST design\n\nIntegrate using predictable HTTP methods, JSON payloads, consistent error formats, and versioned endpoints.\n\n**Proof point:** Cursor-based pagination, filtering, sorting, OpenAPI documentation, and RFC-style problem responses make the API easier to build against and operate.\n\n### Security and scale built into the architecture\n\nSupport production operations with:\n\n- Audit events\n- Strong transport and cookie controls\n- Configurable authorization policies\n- API versioning\n- Key rotation support\n- Monitoring and abuse detection hooks\n\n---\n\n## 4.

Developer documentation copy\n\n### Introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10.

Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- Support UTF-8\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Browser applications\n\nUse:\n\n- Short-lived access tokens: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh tokens\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\n### APIs and native clients\n\nUse:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11.

Simple APIs. Scalable control.**\n\n### Core promise\n\nThe User Management API gives development teams a secure, flexible foundation for registration, authentication, authorization, session management, and administrative user operations—without requiring them to build identity infrastructure from scratch.\n\n---\n\n## 1. Target audiences\n\n### Primary audiences\n\n- Backend and full-stack developers\n- Engineering managers and technical leads\n- SaaS and platform teams\n- Startup founders building customer-facing products\n- Security and compliance leaders\n- Product teams launching applications with account-based experiences\n\n### Ideal use cases\n\n- SaaS account management\n- B2B applications with multiple roles\n- Customer portals\n- Internal tools and workforce applications\n- Developer platforms\n- Applications requiring secure sessions and administrative controls\n\n### Buyer concerns\n\n- Authentication security and password handling\n- Time required to build and maintain identity features\n- Role-based access control\n- Session revocation and token security\n- Scalability and reliability\n- Auditability and compliance readiness\n- Developer experience and integration speed\n\n---\n\n## 2. Positioning\n\n### Positioning statement\n\nFor engineering teams that need reliable identity capabilities, the User Management API is a developer-friendly REST API that provides secure authentication, role-based authorization, session management, and scalable administration through clear, versioned endpoints.\n\nUnlike a basic login service, it supports the broader user lifecycle—from registration and email verification to password resets, session revocation, role management, and audit events.\n\n### Competitive distinction\n\nEmphasize that the API combines:\n\n- Production-minded security controls\n- Straightforward REST resources\n- Flexible browser and native-client authentication strategies\n- Built-in administrative workflows\n- Clear error responses and validation\n- Pagination, filtering, and versioning for long-term maintainability\n\nDo not claim that the API eliminates all security or compliance work. Position it as a strong foundation that helps teams implement identity capabilities consistently.\n\n---\n\n## 3. Key messaging\n\n### Secure authentication from day one\n\nSupport:\n\n- Registration and email verification\n- Argon2id password hashing\n- Password reset flows\n- Short-lived access tokens\n- Rotating refresh tokens\n- Refresh-token reuse detection\n- Session revocation\n- Rate limiting and abuse prevention\n\n**Proof point:** Passwords, tokens, and sensitive security metadata are never exposed through user responses.\n\n### Authorization that matches your organization\n\nUse role-based access control for users, support teams, administrators, and security administrators.\n\n**Proof point:** Combine role checks with resource ownership rules so users can manage their own profiles while privileged teams handle administrative operations.\n\n### Manage the complete user lifecycle\n\nHandle more than login:\n\n- Create and verify accounts\n- Update profiles\n- Suspend or deactivate users\n- Reset passwords\n- Review active sessions\n- Revoke individual or all sessions\n- Assign roles\n- Record administrative actions\n\n### Developer-friendly REST design\n\nIntegrate using predictable HTTP methods, JSON payloads, consistent error formats, and versioned endpoints.\n\n**Proof point:** Cursor-based pagination, filtering, sorting, OpenAPI documentation, and RFC-style problem responses make the API easier to build against and operate.\n\n### Security and scale built into the architecture\n\nSupport production operations with:\n\n- Audit events\n- Strong transport and cookie controls\n- Configurable authorization policies\n- API versioning\n- Key rotation support\n- Monitoring and abuse detection hooks\n\n---\n\n## 4.

Developer documentation copy\n\n### Introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- Support UTF-8\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Browser applications\n\nUse:\n\n- Short-lived access tokens: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh tokens\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\n### APIs and native clients\n\nUse:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11. Security controls\n\n### Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n### Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n### CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n### Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n## 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n## 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n## 14.

Developer documentation copy\n\n### Introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6.

Administrative endpoints\n\n### List users\n\n```http\nGET /v1/users\nAuthorization: Bearer \n```\n\nSupported query parameters:\n\n```text\n?limit=25\n&cursor=eyJpZCI6InVzcl8...\n&status=active\n&role=user\n&emailVerified=true\n&search=alex\n&sort=-createdAt\n```\n\nResponse:\n\n```json\n{\n \"data\": [\n {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"firstName\": \"Alex\",\n \"lastName\": \"Morgan\",\n \"status\": \"active\",\n \"roles\": [\"user\"],\n \"emailVerified\": true,\n \"createdAt\": \"2025-01-15T10:30:00Z\"\n }\n ],\n \"pagination\": {\n \"limit\": 25,\n \"nextCursor\": \"eyJpZCI6InVzcl8...\",\n \"hasMore\": true\n }\n}\n```\n\nUse cursor-based pagination for production endpoints and enforce a maximum `limit`, such as `100`.\n\n### Update a user as an administrator\n\n```http\nPATCH /v1/users/{userId}\nAuthorization: Bearer \nContent-Type: application/json\n```\n\nRequest:\n\n```json\n{\n \"status\": \"suspended\",\n \"roles\": [\"user\"],\n \"suspensionReason\": \"Repeated policy violations\"\n}\n```\n\nResponse:\n\n```json\n{\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"status\": \"suspended\",\n \"roles\": [\"user\"],\n \"updatedAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nProtect role changes with:\n\n- Admin-only authorization\n- Audit logging\n- Optional dual approval for privileged roles\n- Prevention of accidental removal of the last administrator\n\n### List a user’s sessions\n\n```http\nGET /v1/users/me/sessions\nAuthorization: Bearer \n```\n\nResponse:\n\n```json\n{\n \"data\": [\n {\n \"id\": \"ses_01HZ...\",\n \"device\": \"Chrome on macOS\",\n \"ipAddress\": \"203.0.113.10\",\n \"createdAt\": \"2025-01-15T10:30:00Z\",\n \"lastUsedAt\": \"2025-01-20T14:10:00Z\",\n \"current\": true\n }\n ]\n}\n```\n\nDo not expose raw token values.\n\nRevoke a session:\n\n```http\nDELETE /v1/users/me/sessions/{sessionId}\nAuthorization: Bearer \n```\n\n---\n\n## 6. Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- Support UTF-8\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Browser applications\n\nUse:\n\n- Short-lived access tokens: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh tokens\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\n### APIs and native clients\n\nUse:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11. Security controls\n\n### Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n### Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n### CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n### Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n## 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n## 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n## 14.

Implementation checklist\n\n- [ ] Define the OpenAPI contract\n- [ ] Implement users, roles, sessions, and audit tables\n- [ ] Add Argon2id password hashing\n- [ ] Implement token rotation and reuse detection\n- [ ] Add email verification and password reset workflows\n- [ ] Add authorization middleware and ownership checks\n- [ ] Add rate limits and abuse detection\n- [ ] Add structured audit events\n- [ ] Add automated security, contract, and integration tests\n- [ ] Configure monitoring, alerting, and key rotation\n- [ ] Perform threat modeling and penetration testing before launch\n\n---\n\n# Part II: Promotional Campaign\n\n## Campaign theme\n\n**Build identity infrastructure developers can trust.**\n\n### Campaign tagline\n\n**Secure users. Simple APIs. Scalable control.**\n\n### Core promise\n\nThe User Management API gives development teams a secure, flexible foundation for registration, authentication, authorization, session management, and administrative user operations—without requiring them to build identity infrastructure from scratch.\n\n---\n\n## 1. Target audiences\n\n### Primary audiences\n\n- Backend and full-stack developers\n- Engineering managers and technical leads\n- SaaS and platform teams\n- Startup founders building customer-facing products\n- Security and compliance leaders\n- Product teams launching applications with account-based experiences\n\n### Ideal use cases\n\n- SaaS account management\n- B2B applications with multiple roles\n- Customer portals\n- Internal tools and workforce applications\n- Developer platforms\n- Applications requiring secure sessions and administrative controls\n\n### Buyer concerns\n\n- Authentication security and password handling\n- Time required to build and maintain identity features\n- Role-based access control\n- Session revocation and token security\n- Scalability and reliability\n- Auditability and compliance readiness\n- Developer experience and integration speed\n\n---\n\n## 2. Positioning\n\n### Positioning statement\n\nFor engineering teams that need reliable identity capabilities, the User Management API is a developer-friendly REST API that provides secure authentication, role-based authorization, session management, and scalable administration through clear, versioned endpoints.\n\nUnlike a basic login service, it supports the broader user lifecycle—from registration and email verification to password resets, session revocation, role management, and audit events.\n\n### Competitive distinction\n\nEmphasize that the API combines:\n\n- Production-minded security controls\n- Straightforward REST resources\n- Flexible browser and native-client authentication strategies\n- Built-in administrative workflows\n- Clear error responses and validation\n- Pagination, filtering, and versioning for long-term maintainability\n\nDo not claim that the API eliminates all security or compliance work. Position it as a strong foundation that helps teams implement identity capabilities consistently.\n\n---\n\n## 3. Key messaging\n\n### Secure authentication from day one\n\nSupport:\n\n- Registration and email verification\n- Argon2id password hashing\n- Password reset flows\n- Short-lived access tokens\n- Rotating refresh tokens\n- Refresh-token reuse detection\n- Session revocation\n- Rate limiting and abuse prevention\n\n**Proof point:** Passwords, tokens, and sensitive security metadata are never exposed through user responses.\n\n### Authorization that matches your organization\n\nUse role-based authorization for users, support teams, administrators, and security administrators.\n\n**Proof point:** Combine role checks with resource ownership rules so users can manage their own profiles while privileged teams handle administrative operations.\n\n### Manage the complete user lifecycle\n\nHandle more than login:\n\n- Create and verify accounts\n- Update profiles\n- Suspend or deactivate users\n- Reset passwords\n- Review active sessions\n- Revoke individual or all sessions\n- Assign roles\n- Record administrative actions\n\n### Developer-friendly REST design\n\nIntegrate using predictable HTTP methods, JSON payloads, consistent error formats, and versioned endpoints.\n\n**Proof point:** Cursor-based pagination, filtering, sorting, OpenAPI documentation, and RFC-style problem responses make the API easier to build against and operate.\n\n### Security and scale built into the architecture\n\nSupport production operations with:\n\n- Audit events\n- Strong transport and cookie controls\n- Configurable authorization policies\n- API versioning\n- Key rotation support\n- Monitoring and abuse detection hooks\n\n---\n\n## 4.

Developer documentation copy\n\n### Introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6.

Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11. Security controls\n\n### Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n### Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n### CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n### Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n## 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n## 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n## 14.

Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11. Security controls\n\n### Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n### Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n### CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n### Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n## 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n## 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n## 14.

Validation rules\n\n### Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n### Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n### Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n## 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n## 8. Token and session strategy\n\n### Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n## 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n## 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n## 11. Security controls\n\n### Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n### Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n### CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n### Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n## 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n## 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n## 14.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Validation rules\n\n## Email\n\n- Required during registration\n- Normalize domain casing\n- Store a canonical representation\n- Validate syntax and maximum length\n- Enforce uniqueness using a database constraint\n- Do not rely only on application-level uniqueness checks\n\n## Names\n\n- UTF-8 supported\n- Maximum length, for example 100 characters\n- Reject control characters\n- Trim leading and trailing whitespace\n\n## Passwords\n\nRecommended rules:\n\n- Minimum length: 12 characters\n- Maximum length: at least 128 characters\n- Accept spaces and Unicode\n- Do not require arbitrary composition rules\n- Reject known breached passwords using a breach-password service or local corpus\n- Never log or persist plaintext passwords\n\nExample validation response:\n\n```json\n{\n \"type\": \"https://api.example.com/problems/validation-error\",\n \"title\": \"Validation failed\",\n \"status\": 422,\n \"code\": \"VALIDATION_ERROR\",\n \"detail\": \"One or more fields are invalid.\",\n \"errors\": [\n {\n \"field\": \"password\",\n \"code\": \"PASSWORD_TOO_SHORT\",\n \"message\": \"Password must contain at least 12 characters.\"\n }\n ],\n \"requestId\": \"req_01HZ...\"\n}\n```\n\n---\n\n# 7. Password handling\n\nUse Argon2id with parameters calibrated for the production environment.\n\nExample conceptual configuration:\n\n```text\nalgorithm: Argon2id\nmemory: 64 MiB or higher\niterations: 3+\nparallelism: 1–4\nsalt: unique random salt per password\n```\n\nExample server-side pseudocode:\n\n```python\nfrom argon2 import PasswordHasher\n\npassword_hasher = PasswordHasher(\n time_cost=3,\n memory_cost=65536,\n parallelism=2\n)\n\npassword_hash = password_hasher.hash(plain_password)\n\ntry:\n password_hasher.verify(password_hash, submitted_password)\nexcept VerifyMismatchError:\n raise InvalidCredentials()\n```\n\nAdditional controls:\n\n- Rehash passwords when parameters become outdated\n- Use constant-time comparison where applicable\n- Rate-limit login and password reset attempts\n- Revoke sessions after password changes\n- Never send passwords by email\n- Never include credentials in URLs\n\n---\n\n# 8. Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Simple APIs. Scalable control.**\n\n### Core promise\n\nThe User Management API gives development teams a secure, flexible foundation for registration, authentication, authorization, session management, and administrative user operations—without requiring them to build identity infrastructure from scratch.\n\n---\n\n## 1. Target audiences\n\n### Primary audiences\n\n- Backend and full-stack developers\n- Engineering managers and technical leads\n- SaaS and platform teams\n- Startup founders building customer-facing products\n- Security and compliance leaders\n- Product teams launching applications with account-based experiences\n\n### Ideal use cases\n\n- SaaS account management\n- B2B applications with multiple roles\n- Customer portals\n- Internal tools and workforce applications\n- Developer platforms\n- Applications requiring secure sessions and administrative controls\n\n### Buyer concerns\n\n- Authentication security and password handling\n- Time required to build and maintain identity features\n- Role-based access control\n- Session revocation and token security\n- Scalability and reliability\n- Auditability and compliance readiness\n- Developer experience and integration speed\n\n---\n\n## 2. Positioning\n\n### Positioning statement\n\nFor engineering teams that need reliable identity capabilities, the User Management API is a developer-friendly REST API that provides secure authentication, role-based authorization, session management, and scalable administration through clear, versioned endpoints.\n\nUnlike a basic login service, it supports the broader user lifecycle—from registration and email verification to password resets, session revocation, role management, and audit events.\n\n### Competitive distinction\n\nEmphasize that the API combines:\n\n- Production-minded security controls\n- Straightforward REST resources\n- Flexible browser and native-client authentication strategies\n- Built-in administrative workflows\n- Clear error responses and validation\n- Pagination, filtering, and versioning for long-term maintainability\n\nAvoid claiming that the API eliminates all security or compliance work.

Developer documentation copy\n\n### Documentation introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6.

Token and session strategy\n\n## Recommended approach\n\nFor browser applications:\n\n- Short-lived access token: 10–15 minutes\n- Secure, `HttpOnly`, `SameSite` cookies\n- Opaque, rotating refresh token\n- Server-side refresh-token persistence\n- Refresh-token family tracking and reuse detection\n\nFor APIs and native clients:\n\n```http\nAuthorization: Bearer \n```\n\nAccess tokens may be JWTs containing only minimal claims:\n\n```json\n{\n \"iss\": \"https://api.example.com\",\n \"sub\": \"usr_01HZX8Y7K3N4Q2\",\n \"aud\": \"user-management-api\",\n \"jti\": \"tok_01HZ...\",\n \"iat\": 1736951400,\n \"exp\": 1736952300,\n \"roles\": [\"user\"]\n}\n```\n\nRecommendations:\n\n- Sign JWTs with an asymmetric algorithm such as RS256 or EdDSA\n- Publish public keys through a JWKS endpoint\n- Rotate signing keys\n- Validate issuer, audience, expiration, signature, and token ID\n- Do not place sensitive information in JWT claims\n- Keep authorization decisions server-side for high-risk operations\n\nA session record may contain:\n\n```text\nid\nuser_id\nrefresh_token_hash\ntoken_family_id\ndevice_metadata\nip_address\ncreated_at\nlast_used_at\nexpires_at\nrevoked_at\n```\n\nStore only hashes of opaque refresh tokens.\n\n---\n\n# 9. Authorization\n\nUse role-based access control combined with resource ownership checks.\n\nExample policy:\n\n| Operation | User | Support | Admin | Security Admin |\n|---|---:|---:|---:|---:|\n| Read own profile | Yes | Yes | Yes | Yes |\n| Update own profile | Yes | No | Yes | Yes |\n| List users | No | Yes | Yes | Yes |\n| Suspend users | No | No | Yes | Yes |\n| Assign roles | No | No | Yes | Yes |\n| Revoke all sessions | Own only | No | Yes | Yes |\n| Change authentication policy | No | No | No | Yes |\n\nAuthorization middleware example:\n\n```typescript\nfunction requireRole(...allowedRoles: string[]) {\n return (req, res, next) => {\n const hasRole = req.user.roles.some((role: string) =>\n allowedRoles.includes(role)\n );\n\n if (!hasRole) {\n return next(new ForbiddenError());\n }\n\n next();\n };\n}\n```\n\nEvery endpoint should also verify that the requested resource belongs to the authenticated user where applicable.\n\n---\n\n# 10. Error format\n\nUse an RFC 9457/RFC 7807-style problem response.\n\n```json\n{\n \"type\": \"https://api.example.com/problems/invalid-credentials\",\n \"title\": \"Invalid credentials\",\n \"status\": 401,\n \"code\": \"INVALID_CREDENTIALS\",\n \"detail\": \"The email or password is incorrect.\",\n \"requestId\": \"req_01HZ...\"\n}\n```\n\nStandard status codes:\n\n- `400 Bad Request`: Malformed request\n- `401 Unauthorized`: Missing or invalid authentication\n- `403 Forbidden`: Authenticated but not authorized\n- `404 Not Found`: Resource does not exist\n- `409 Conflict`: State or uniqueness conflict\n- `422 Unprocessable Entity`: Validation failure\n- `429 Too Many Requests`: Rate limit exceeded\n- `500 Internal Server Error`: Unexpected server failure\n\nAvoid exposing whether an email exists in login, registration, and password-reset flows.\n\n---\n\n# 11. Security controls\n\n## Transport and headers\n\n- TLS 1.2 or later\n- HSTS\n- Secure and HttpOnly cookies\n- `SameSite=Lax` or `Strict`\n- Content Security Policy for web clients\n- `X-Content-Type-Options: nosniff`\n- Strict CORS allowlist\n- No credentials in query parameters\n\n## Abuse prevention\n\n- Rate-limit login by IP and account identifier\n- Rate-limit registration and password reset\n- Progressive delays or temporary lockouts\n- CAPTCHA or step-up verification after suspicious activity\n- Detect credential stuffing and impossible travel\n- Use generic authentication error messages\n\n## CSRF\n\nIf cookies are used:\n\n- Use SameSite cookies\n- Add CSRF tokens for state-changing requests\n- Validate the `Origin` header\n- Do not permit overly broad CORS\n\n## Auditing and monitoring\n\nAudit:\n\n- Login success and failure\n- Password changes and resets\n- Email changes\n- Role changes\n- Account suspension and deletion\n- Session creation and revocation\n- Administrative access\n\nAudit records should include:\n\n```json\n{\n \"event\": \"user.role_changed\",\n \"actorId\": \"usr_admin\",\n \"targetUserId\": \"usr_01HZ...\",\n \"metadata\": {\n \"oldRoles\": [\"user\"],\n \"newRoles\": [\"support\"]\n },\n \"ipAddress\": \"203.0.113.10\",\n \"occurredAt\": \"2025-01-20T15:00:00Z\"\n}\n```\n\nDo not log passwords, tokens, or full authorization headers.\n\n---\n\n# 12. Data model\n\nExample relational schema:\n\n```sql\nCREATE TABLE users (\n id UUID PRIMARY KEY,\n email TEXT NOT NULL,\n email_normalized TEXT NOT NULL UNIQUE,\n password_hash TEXT NOT NULL,\n first_name TEXT NOT NULL,\n last_name TEXT NOT NULL,\n status TEXT NOT NULL CHECK (status IN (\n 'pending_verification',\n 'active',\n 'suspended',\n 'deleted'\n )),\n email_verified_at TIMESTAMPTZ,\n created_at TIMESTAMPTZ NOT NULL,\n updated_at TIMESTAMPTZ NOT NULL,\n deleted_at TIMESTAMPTZ\n);\n\nCREATE TABLE user_roles (\n user_id UUID NOT NULL REFERENCES users(id),\n role TEXT NOT NULL,\n PRIMARY KEY (user_id, role)\n);\n\nCREATE TABLE sessions (\n id UUID PRIMARY KEY,\n user_id UUID NOT NULL REFERENCES users(id),\n refresh_token_hash TEXT NOT NULL,\n token_family_id UUID NOT NULL,\n created_at TIMESTAMPTZ NOT NULL,\n last_used_at TIMESTAMPTZ NOT NULL,\n expires_at TIMESTAMPTZ NOT NULL,\n revoked_at TIMESTAMPTZ\n);\n\nCREATE TABLE audit_events (\n id UUID PRIMARY KEY,\n actor_user_id UUID REFERENCES users(id),\n target_user_id UUID REFERENCES users(id),\n event_type TEXT NOT NULL,\n metadata JSONB,\n ip_address INET,\n created_at TIMESTAMPTZ NOT NULL\n);\n```\n\nUse database indexes for:\n\n- `email_normalized`\n- `status`\n- `created_at`\n- `user_roles.role`\n- Cursor-pagination fields\n\n---\n\n# 13. Versioning and compatibility\n\nUse URL-based major versioning:\n\n```text\n/v1/users\n/v2/users\n```\n\nRules:\n\n- Backward-compatible fields may be added without a version change\n- Do not rename or remove fields in an existing major version\n- Deprecate endpoints using the `Deprecation` and `Sunset` headers\n- Publish an OpenAPI document for every supported version\n- Maintain contract and integration tests\n- Announce breaking changes before sunset\n\nExample:\n\n```http\nDeprecation: true\nSunset: Wed, 31 Dec 2025 23:59:59 GMT\nLink: ; rel=\"successor-version\"\n```\n\n---\n\n# 14.

Simple APIs. Scalable control.**\n\n### Core promise\n\nThe User Management API gives development teams a secure, flexible foundation for registration, authentication, authorization, session management, and administrative user operations—without requiring them to build identity infrastructure from scratch.\n\n---\n\n## 1. Target audiences\n\n### Primary audiences\n\n- Backend and full-stack developers\n- Engineering managers and technical leads\n- SaaS and platform teams\n- Startup founders building customer-facing products\n- Security and compliance leaders\n- Product teams launching applications with account-based experiences\n\n### Ideal use cases\n\n- SaaS account management\n- B2B applications with multiple roles\n- Customer portals\n- Internal tools and workforce applications\n- Developer platforms\n- Applications requiring secure sessions and administrative controls\n\n### Buyer concerns\n\n- Authentication security and password handling\n- Time required to build and maintain identity features\n- Role-based access control\n- Session revocation and token security\n- Scalability and reliability\n- Auditability and compliance readiness\n- Developer experience and integration speed\n\n---\n\n## 2. Positioning\n\n### Positioning statement\n\nFor engineering teams that need reliable identity capabilities, the User Management API is a developer-friendly REST API that provides secure authentication, role-based authorization, session management, and scalable administration through clear, versioned endpoints.\n\nUnlike a basic login service, it supports the broader user lifecycle—from registration and email verification to password resets, session revocation, role management, and audit events.\n\n### Competitive distinction\n\nEmphasize that the API combines:\n\n- Production-minded security controls\n- Straightforward REST resources\n- Flexible browser and native-client authentication strategies\n- Built-in administrative workflows\n- Clear error responses and validation\n- Pagination, filtering, and versioning for long-term maintainability\n\nAvoid claiming that the API eliminates all security or compliance work. Position it as a strong foundation that helps teams implement identity capabilities consistently.\n\n---\n\n## 3. Key messaging\n\n### Message 1: Secure authentication from day one\n\nSupport modern authentication workflows, including:\n\n- Registration and email verification\n- Argon2id password hashing\n- Password reset flows\n- Short-lived access tokens\n- Rotating refresh tokens\n- Refresh-token reuse detection\n- Session revocation\n- Rate limiting and abuse prevention\n\n**Proof point:** Passwords, tokens, and sensitive security metadata are never exposed through user responses.\n\n### Message 2: Authorization that matches your organization\n\nUse role-based access control for users, support teams, administrators, and security administrators.\n\n**Proof point:** Combine role checks with resource ownership rules so users can manage their own profiles while privileged teams handle administrative operations.\n\n### Message 3: Manage the complete user lifecycle\n\nHandle more than login:\n\n- Create and verify accounts\n- Update profiles\n- Suspend or deactivate users\n- Reset passwords\n- Review active sessions\n- Revoke individual or all sessions\n- Assign roles\n- Record administrative actions\n\n### Message 4: Developer-friendly REST design\n\nIntegrate using predictable HTTP methods, JSON payloads, consistent error formats, and versioned endpoints.\n\n**Proof point:** Cursor-based pagination, filtering, sorting, OpenAPI documentation, and RFC-style problem responses make the API easier to build against and operate.\n\n### Message 5: Security and scale built into the architecture\n\nSupport production operations with:\n\n- Audit events\n- Strong transport and cookie controls\n- Configurable authorization policies\n- API versioning\n- Key rotation support\n- Monitoring and abuse detection hooks\n\n---\n\n## 4.

Developer documentation copy\n\n### Documentation introduction\n\n# User Management API\n\nThe User Management API provides REST endpoints for account creation, authentication, profile management, authorization, session control, and administrative user operations.\n\nAll endpoints are available under:\n\n```text\nhttps://api.example.com/v1\n```\n\nRequests and responses use JSON unless otherwise noted.\n\n### Quick-start sequence\n\n1. Register a user.\n2. Verify the user’s email address.\n3. Authenticate with email and password.\n4. Use the access token to retrieve the current user.\n5. Refresh the session when the access token expires.\n6. Revoke sessions when the user logs out or security requires it.\n\n### Example request\n\n```bash\ncurl -X POST https://api.example.com/v1/auth/login \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"email\": \"alex@example.com\",\n \"password\": \"correct horse battery staple\"\n }'\n```\n\n### Example response\n\n```json\n{\n \"accessToken\": \"eyJhbGciOiJSUzI1NiIs...\",\n \"tokenType\": \"Bearer\",\n \"expiresIn\": 900,\n \"user\": {\n \"id\": \"usr_01HZX8Y7K3N4Q2\",\n \"email\": \"alex@example.com\",\n \"roles\": [\"user\"],\n \"status\": \"active\"\n }\n}\n```\n\n### Security note\n\nAccess tokens should be kept short-lived. Refresh tokens should be stored securely, rotated on use, and revoked when misuse is detected. Never log passwords, refresh tokens, or authorization headers.\n\n---\n\n## 6. Email campaign\n\n### Pre-launch email\n\n**Subject:** A better foundation for authentication and user management\n\nBuilding login, roles, sessions, and account administration from scratch takes time—and security mistakes can be costly.\n\nWe’re launching the User Management API: a developer-friendly REST API for secure authentication, role-based access control, session management, and scalable user administration.\n\nWith clear endpoints and production-minded security controls, your team can:\n\n- Register and authenticate users\n- Verify email addresses and reset passwords\n- Manage roles and account status\n- Revoke individual or all sessions\n- Integrate with versioned, documented REST endpoints\n\n**CTA:** Preview the API documentation\n\n### Launch email\n\n**Subject:** Meet the User Management API\n\nSecure your application’s user lifecycle with one flexible API.\n\nThe User Management API includes:\n\n- Argon2id password handling\n- Short-lived access tokens\n- Rotating refresh tokens\n- Role-based authorization\n- Session listing and revocation\n- Administrative user management\n- Cursor-based pagination and filtering\n- Structured validation and error responses\n\n**Start with the quick-start guide and build your first authenticated workflow today.**\n\n**CTA:** Start building\n\n### Follow-up email\n\n**Subject:** Five user-management features your team shouldn’t build twice\n\nA production-ready account system involves much more than a login form.\n\nThe User Management API helps cover the essential workflows:\n\n1.

Most forecasts imply **30–45% CAGR through 2030**, potentially reaching **$150–200+ billion**. The largest near-term pools are clinical documentation and workflow automation, imaging and diagnostics, patient engagement, revenue-cycle management, and pharmaceutical R&D.\n\n- **Most attractive entry opportunities:** Near-term adoption is strongest where ROI is measurable and clinical risk is limited: **ambient clinical documentation, prior-authorization automation, coding and billing, call-center copilots, care navigation, clinical-trial recruitment, and diagnostic workflow support**. Selling directly to hospitals is difficult because of long procurement cycles and integration requirements; partnering with **EHR vendors, specialty-care platforms, payers, health systems, or existing clinical software providers** can materially reduce distribution friction. A focused vertical—such as oncology, radiology, cardiology, or behavioral health—is generally more defensible than a horizontal “AI for healthcare” proposition.\n\n- **Competitive landscape and differentiation:** Major platforms include **Microsoft/Nuance, Google Cloud, AWS, Oracle, Salesforce, Epic, and NVIDIA**; healthcare incumbents such as **GE HealthCare, Siemens Healthineers, Philips, Medtronic, Tempus, PathAI, Aidoc, Viz.ai, Abridge, and Suki** compete across clinical, imaging, documentation, and precision-medicine segments. New entrants face commoditization of foundation models, so defensibility should come from **proprietary clinical data, validated outcomes, deep workflow integration, specialty-specific models, distribution partnerships, and regulatory/compliance capabilities**—not simply from using a better general-purpose model.\n\n- **Entry risks and recommended strategy:** The main barriers are **HIPAA/GDPR and emerging AI regulation, FDA clearance for diagnostic or treatment claims, patient-safety liability, biased or hallucinated outputs, cybersecurity, EHR interoperability, and proving economic value**. A practical entry plan is to launch a **human-in-the-loop, non-diagnostic workflow product**, secure a design partnership with one or two health systems, demonstrate metrics such as clinician time saved, denial-rate reduction, diagnostic sensitivity, or cost per encounter, then expand through channel partners.

Requirements differ across the FDA, EU MDR/AI Act, UK, and other jurisdictions; privacy obligations such as HIPAA, GDPR, and health-data localization add complexity. Liability is also unresolved: hospitals, clinicians, developers, and cloud providers may share responsibility when an AI recommendation causes harm. **Entry implication:** begin with a narrowly defined, lower-risk use case—such as workflow automation or administrative intelligence—then build toward clinical decision support with prospective validation, audit trails, human oversight, model-change controls, and a jurisdiction-specific regulatory plan.\n\n- **Technical and clinical risk — high impact and difficult to validate:** Healthcare data is fragmented, biased, poorly labeled, and often incompatible across EHRs, imaging systems, laboratories, and payer platforms. Models that perform well in development may degrade across hospitals, demographic groups, disease prevalence, workflows, or equipment configurations. Generative systems introduce hallucination, automation bias, prompt-injection, data leakage, and explainability concerns; cybersecurity threats can directly affect patient safety. **Entry implication:** prioritize measurable clinical outcomes over benchmark accuracy; conduct external and prospective validation, subgroup and fairness testing, calibration, monitoring for drift, security assessments, interoperability work, and “human-in-the-loop” deployment with clear escalation procedures. Lack of reimbursement or workflow integration can make a technically strong product commercially unusable.\n\n- **Competitive and commercial risk — potentially decisive:** The market includes EHR vendors, medical-device companies, insurers, health systems, cloud providers, foundation-model firms, and specialized startups. Large incumbents possess distribution, procurement relationships, proprietary data, regulatory infrastructure, and the ability to bundle AI into existing contracts. Foundation models may commoditize generic capabilities, reducing pricing power, while hospitals often have long sales cycles, strict integration requirements, limited budgets, and fragmented purchasing authority. **Entry implication:** avoid undifferentiated “AI assistant” positioning; target a high-value workflow with a clear economic buyer and quantifiable ROI, secure distribution through EHR or provider partnerships, develop proprietary workflow/data advantages, and create switching costs through validated integrations and longitudinal performance evidence.\n\n- **Overall market-entry judgment:** Attractive opportunities exist, particularly where AI reduces administrative burden, improves diagnostics, supports chronic-care management, or accelerates drug development—but success depends less on model novelty than on regulatory readiness, clinical evidence, interoperability, reimbursement, and trust.

The strongest opportunities are not necessarily the most clinically ambitious. Near-term winners are likely to be products that:\n\n- Address expensive, repetitive workflows\n- Produce measurable financial or operational ROI\n- Fit into existing clinical systems\n- Keep humans responsible for consequential decisions\n- Avoid unnecessary regulatory exposure during initial commercialization\n- Build defensibility through proprietary data, validated outcomes, workflow integration, and distribution\n\nA practical market-entry strategy would begin with a narrowly scoped, human-in-the-loop product in administrative or workflow automation—such as clinical documentation, prior authorization, coding, billing, care navigation, or clinical-trial recruitment. The company should validate the product with one or two health-system design partners, demonstrate measurable results, and then expand through EHR vendors, specialty-care platforms, payers, health systems, or existing clinical software providers.\n\nAutonomous diagnosis or treatment recommendations may offer greater long-term value but involve substantially greater regulatory, clinical, liability, validation, and reimbursement risk.\n\n---\n\n## 1. Market size and growth\n\nThe global AI-in-healthcare market is estimated at approximately **$25–35 billion in 2023–24**, depending on whether the definition includes:\n\n- Drug discovery\n- Medical devices\n- Clinical software\n- Administrative automation\n- Imaging and diagnostics\n- Patient engagement\n- Revenue-cycle management\n- Pharmaceutical research and development\n\nMost industry forecasts imply approximately **30–45% compound annual growth through 2030**, potentially producing a market of approximately **$150–200+ billion** by that point.\n\nThe headline market is broad, however, and contains segments with very different commercial characteristics. For an entrant, the more relevant question is not simply whether the market is growing, but which submarkets have:\n\n1. A clear economic buyer \n2. An urgent operational or clinical problem \n3. Available data and system access \n4. Manageable regulatory exposure \n5. A measurable return on investment \n6. A viable distribution path \n\n### Major near-term spending pools\n\nThe largest practical opportunity areas include:\n\n- Clinical documentation and workflow automation\n- Imaging and diagnostic support\n- Patient engagement and care navigation\n- Revenue-cycle management\n- Prior-authorization automation\n- Coding and billing\n- Call-center and clinician copilots\n- Clinical-trial recruitment\n- Pharmaceutical R&D and drug discovery\n\nAdoption is generally strongest where the economic benefit is easy to quantify and the AI system does not independently make high-consequence clinical decisions.\n\n---\n\n## 2. Most attractive entry opportunities\n\n### A. Ambient clinical documentation\n\nAmbient documentation systems listen to clinical encounters and generate draft notes, summaries, or structured data for clinician review.\n\n**Why the segment is attractive:**\n\n- Clinician administrative burden is substantial\n- Time saved is relatively easy to measure\n- The buyer can often connect the product to productivity, burnout reduction, and encounter capacity\n- Human review can remain central to the workflow\n- The product can initially avoid autonomous diagnosis or treatment claims\n\n**Key challenges:**\n\n- Accuracy and completeness of clinical notes\n- Patient consent and privacy\n- EHR integration\n- Potential exposure to sensitive information\n- Competition from major vendors and specialized companies\n- Need to demonstrate that documentation quality does not deteriorate\n\nA product should be positioned as a documentation assistant rather than an autonomous clinical decision-maker. Metrics could include clinician time saved, note completion time, after-hours work, documentation quality, and clinician adoption.\n\n---\n\n### B. Prior-authorization automation\n\nAI can help collect required documentation, determine whether authorization criteria are likely to be met, prepare submissions, and track payer responses.\n\n**Why the segment is attractive:**\n\n- Prior authorization creates clear administrative costs and delays\n- The workflow has identifiable users and economic buyers\n- Denial-rate reduction and turnaround-time improvements can be quantified\n- The product can support rather than replace clinical judgment\n\n**Potential value metrics:**\n\n- Reduction in submission preparation time\n- Reduction in denial rates\n- Faster authorization turnaround\n- Fewer incomplete submissions\n- Reduction in staff labor per authorization\n- Improvement in patient access and scheduling reliability\n\n**Risks:**\n\n- Payer policy changes\n- Errors in interpreting coverage rules\n- Potential liability if the system causes inappropriate delays\n- Fragmented payer and provider systems\n- Need for explainable recommendations and audit trails\n\n---\n\n### C. Coding, billing, and revenue-cycle management\n\nAI can assist with medical coding, claims preparation, denial management, documentation review, and revenue-cycle workflows.\n\n**Why the segment is attractive:**\n\n- Financial ROI can be directly measured\n- Buyers may have more immediate purchasing authority than clinical departments\n- The system can often remain subject to human review\n- The value proposition can be tied to revenue recovered, denial reduction, or labor savings\n\n**Important metrics:**\n\n- Denial-rate reduction\n- Clean-claim rate\n- Revenue recovered\n- Cost per claim or encounter\n- Coding accuracy\n- Days in accounts receivable\n- Staff productivity\n\n**Risks:**\n\n- Incorrect coding or overcoding\n- Compliance and audit exposure\n- Changes in payer policies\n- Need to integrate with billing platforms and EHRs\n- Potential legal consequences if automation encourages improper claims\n\nThis is one of the more commercially practical starting points, provided the product includes strong controls, review workflows, auditability, and compliance monitoring.\n\n---\n\n### D. Call-center copilots and patient engagement\n\nAI can assist call-center staff, answer routine patient questions, support scheduling, and route patients to appropriate resources.\n\n**Advantages:**\n\n- High volume and repetitive interactions\n- Measurable staff productivity\n- Potentially lower clinical risk than autonomous diagnosis\n- Clear operational metrics such as response time and call resolution\n\n**Risks:**\n\n- Hallucinated or unsafe health information\n- Poor handling of emergencies\n- Patient privacy concerns\n- Inadequate escalation\n- Prompt injection and data leakage\n- Patient distrust if interactions are not transparent\n\nA safe implementation requires clear boundaries, escalation procedures, emergency detection, human handoff, logging, and restrictions on unsupported clinical advice.\n\n---\n\n### E. Care navigation and chronic-care support\n\nAI can help direct patients through care pathways, remind them about appointments or medication, identify gaps in care, and support chronic-disease management.\n\n**Potential value:**\n\n- Improved patient engagement\n- Reduced missed appointments\n- Better care coordination\n- Earlier identification of care gaps\n- Potential reduction in avoidable utilization\n\n**Challenges:**\n\n- Outcomes may take longer to measure\n- Reimbursement may be unclear\n- Population health data can be fragmented\n- The system may influence patient behavior and therefore create clinical liability\n- Equity and accessibility issues must be tested across demographic groups\n\nThis category can be attractive when tightly aligned with an accountable-care, payer, or value-based-care model.\n\n---\n\n### F. Clinical-trial recruitment\n\nAI can identify potentially eligible patients, match them to trials, and assist with pre-screening.\n\n**Advantages:**\n\n- Significant pharmaceutical and research value\n- Recruitment is often slow and expensive\n- The outcome—qualified enrollment—can be measured\n- The system can support, rather than replace, investigator judgment\n\n**Risks:**\n\n- Patient-consent requirements\n- Incomplete or biased EHR data\n- Incorrect eligibility matching\n- Privacy and data-use restrictions\n- Need for integration with research systems\n\nThis may be a strong entry point for companies with access to clinical data and relationships with pharmaceutical companies, academic medical centers, or specialty-care networks.\n\n---\n\n### G. Diagnostic workflow support\n\nImaging and diagnostic support can help prioritize studies, flag potential abnormalities, organize worklists, or assist clinicians.\n\n**Attractiveness:**\n\n- High potential clinical value\n- Clear workflow bottlenecks in imaging and diagnostics\n- Possibility of measurable improvements in turnaround time, sensitivity, or prioritization\n\n**Risks are materially higher:**\n\n- Products that diagnose, triage, recommend treatment, or influence clinical decisions may qualify as regulated medical devices\n- False negatives or false positives can directly affect patient safety\n- The product may require FDA clearance or equivalent approval\n- Performance can vary across hospitals, equipment, demographics, disease prevalence, and clinical workflows\n- Prospective and external validation may be required\n\nDiagnostic workflow support can be attractive, but it should be entered with a regulatory plan, quality system, audit trails, monitoring, and clear human oversight.\n\n---\n\n### H. Pharmaceutical R&D and drug discovery\n\nAI can support target identification, molecule design, trial planning, and patient selection.\n\n**Potential advantages:**\n\n- Large economic value per successful improvement\n- Strong pharmaceutical demand for productivity gains\n- Less dependence on hospital procurement in some models\n- Opportunities to monetize through partnerships, licensing, or milestone payments\n\n**Challenges:**\n\n- Long development timelines\n- Difficult attribution of value\n- High scientific and validation requirements\n- Data-quality and reproducibility issues\n- Dependence on pharmaceutical development cycles\n- No guarantee that computational performance translates into clinical or commercial success\n\nThis segment may be appropriate for companies with strong scientific capabilities, proprietary datasets, and pharmaceutical partnerships, but it is less suitable for a fast, low-risk initial market entry.\n\n---\n\n## 3. Recommended initial positioning\n\nA focused vertical is generally more defensible than a horizontal proposition such as “AI for healthcare.”\n\nPotential verticals include:\n\n- Oncology\n- Radiology\n- Cardiology\n- Behavioral health\n- Specialty pharmacy\n- Emergency medicine\n- Revenue-cycle operations within a specific specialty\n- Clinical-trial recruitment for a defined disease area\n\nA vertical product can develop:\n\n- Specialty-specific workflows\n- Better data and terminology\n- Stronger clinical validation\n- More relevant integrations\n- More credible sales messaging\n- Higher switching costs\n- More defensible performance data\n\nFor example, a general documentation assistant may be easily compared with large-platform offerings. A documentation and care-coordination system designed specifically for oncology, integrated with oncology-specific workflows and validated on cancer-care outcomes, may be more defensible.\n\n---\n\n## 4. Competitive landscape\n\nThe market includes large technology companies, EHR vendors, medical-device companies, cloud providers, specialized healthcare startups, and foundation-model companies.\n\n### Major platform competitors\n\nImportant large-platform participants include:\n\n- Microsoft/Nuance\n- Google Cloud\n- AWS\n- Oracle\n- Salesforce\n- Epic\n- NVIDIA\n\nThese companies have advantages in:\n\n- Distribution\n- Cloud infrastructure\n- Procurement relationships\n- Existing healthcare contracts\n- Data and computing resources\n- Security and compliance infrastructure\n- Ability to bundle AI into existing products\n\n### Healthcare and specialized competitors\n\nHealthcare incumbents and specialized companies include:\n\n- GE HealthCare\n- Siemens Healthineers\n- Philips\n- Medtronic\n- Tempus\n- PathAI\n- Aidoc\n- Viz.ai\n- Abridge\n- Suki\n\nThey compete across clinical workflows, imaging, documentation, diagnostics, and precision medicine.\n\n### Implications for a new entrant\n\nFoundation models and general-purpose AI capabilities are likely to become increasingly commoditized. A startup is unlikely to maintain a durable advantage simply by using a better general-purpose model.\n\nDefensibility should instead come from:\n\n- Proprietary clinical data\n- Validated outcomes\n- Deep workflow integration\n- Specialty-specific models\n- Distribution partnerships\n- Regulatory and compliance capabilities\n- Longitudinal performance evidence\n- Reliable interoperability\n- Strong trust with clinicians and health-system administrators\n\nThe strategic question is not “Can the company build an AI model?” It is “Can the company reliably embed AI into a critical healthcare workflow and prove that it improves outcomes or economics without creating unacceptable risk?”\n\n---\n\n## 5. Distribution and sales strategy\n\nSelling directly to hospitals can be difficult because of:\n\n- Long procurement cycles\n- Numerous stakeholders\n- Integration requirements\n- Cybersecurity reviews\n- Legal and compliance reviews\n- Fragmented purchasing authority\n- Limited or department-specific budgets\n- Existing vendor commitments\n\nA more efficient route may be to partner with:\n\n- EHR vendors\n- Specialty-care platforms\n- Payers\n- Health systems\n- Existing clinical software providers\n- Medical-device companies\n- Pharmaceutical companies\n- Research networks\n\nThese partnerships can reduce distribution friction and give the product access to established workflows and data.\n\n### Recommended commercial sequence\n\n1. **Choose one high-value workflow**\n - Avoid a broad “AI platform” launch.\n - Define the exact user, workflow, and economic buyer.\n\n2. **Select one care setting or specialty**\n - For example, radiology, oncology, outpatient primary care, or revenue-cycle operations.\n\n3. **Secure one or two design partners**\n - Use health systems or specialty providers to refine workflow, integration, safety, and usability.\n\n4. **Deploy with human review**\n - Treat the system as an assistant, not an autonomous decision-maker.\n\n5. **Measure operational and clinical outcomes**\n - Examples include clinician time saved, denial-rate reduction, diagnostic sensitivity, or cost per encounter.\n\n6. **Build a repeatable integration package**\n - Include EHR connectivity, security documentation, implementation playbooks, and audit capabilities.\n\n7. **Expand through channel partners**\n - Use EHR, payer, specialty-platform, or clinical-software distribution where possible.\n\n8. **Only then broaden into higher-risk clinical functions**\n - Expansion should follow evidence, regulatory readiness, reimbursement alignment, and monitoring capability.\n\n---\n\n## 6. Regulatory and legal risks\n\nRegulatory exposure varies considerably by use case and jurisdiction.\n\n### Medical-device regulation\n\nProducts that diagnose, triage, recommend treatment, or materially influence clinical decisions may qualify as regulated medical devices. Depending on the market, the company may need to demonstrate:\n\n- Safety\n- Performance\n- Clinical validity\n- Quality-system compliance\n- Cybersecurity controls\n- Post-market monitoring\n- Change-management procedures\n\nRequirements differ across:\n\n- The United States and the FDA\n- The European Union under the EU Medical Device Regulation and AI Act\n- The United Kingdom\n- Other national regulatory regimes\n\nThe regulatory classification should be evaluated before product claims, architecture, and commercialization plans are finalized.\n\n### Privacy and data protection\n\nHealthcare data creates obligations under laws and regulations such as:\n\n- HIPAA\n- GDPR\n- Health-data localization requirements\n- National or regional data-protection rules\n\nThe company must address:\n\n- Data minimization\n- Access controls\n- Encryption\n- Retention\n- Consent and permitted use\n- Vendor and cloud-provider arrangements\n- Cross-border data transfers\n- Patient rights\n- Data deletion or correction requirements where applicable\n\n### Liability\n\nLiability is unresolved in many AI healthcare scenarios. Depending on the facts, responsibility may be shared among:\n\n- Developers\n- Hospitals\n- Clinicians\n- Health systems\n- Cloud providers\n- EHR vendors\n- Integrators\n\nPotential liability can arise when an AI recommendation causes:\n\n- A missed diagnosis\n- Inappropriate treatment\n- Delayed care\n- Incorrect triage\n- Improper billing\n- Inaccurate patient communication\n\n### Recommended legal and regulatory posture\n\nStart with a narrowly defined, lower-risk use case such as:\n\n- Workflow automation\n- Administrative intelligence\n- Documentation assistance\n- Revenue-cycle support\n- Prior-authorization support\n\nThen build toward clinical decision support only after developing:\n\n- Prospective validation\n- Audit trails\n- Human oversight\n- Model-change controls\n- Incident-response procedures\n- A jurisdiction-specific regulatory plan\n- Post-market monitoring capabilities\n\n---\n\n## 7. Technical and clinical risks\n\nHealthcare data is often:\n\n- Fragmented\n- Poorly labeled\n- Biased\n- Incomplete\n- Inconsistently structured\n- Distributed across EHRs, imaging systems, laboratories, and payer platforms\n\nA model that performs well in development may degrade when used across:\n\n- Different hospitals\n- Different demographic groups\n- Different disease-prevalence levels\n- Different clinical workflows\n- Different imaging equipment\n- Different documentation styles\n- Different coding or data conventions\n\n### Generative AI-specific risks\n\nGenerative systems add several risks:\n\n- Hallucination\n- Automation bias\n- Prompt injection\n- Data leakage\n- Inadequate explainability\n- Unsafe or incomplete summaries\n- Inconsistent outputs\n- Overreliance by clinicians or staff\n\nCybersecurity is particularly important because attacks may affect not only confidentiality but also patient safety. A compromised system could alter outputs, expose health data, or disrupt clinical operations.\n\n### Required technical controls\n\nA serious healthcare AI product should incorporate:\n\n- External validation\n- Prospective validation where appropriate\n- Subgroup and fairness testing\n- Calibration testing\n- Monitoring for model drift\n- Security assessments\n- Interoperability testing\n- Human-in-the-loop deployment\n- Clear escalation procedures\n- Audit logs\n- Version control\n- Model-change controls\n- Incident-response procedures\n\nThe company should prioritize measurable clinical and operational outcomes over benchmark accuracy alone. A model can achieve strong benchmark performance and still be commercially unusable if it cannot integrate into clinical workflows or does not improve real-world outcomes.\n\n---\n\n## 8. Commercial and competitive risks\n\n### Incumbent bundling\n\nLarge vendors can bundle AI into existing contracts, potentially making it difficult for standalone products to compete on price or distribution.\n\n### Foundation-model commoditization\n\nGeneric AI capabilities may become cheaper and more interchangeable, reducing pricing power for products that lack proprietary workflow or data advantages.\n\n### Hospital buying friction\n\nHospitals frequently have:\n\n- Long sales cycles\n- Strict integration requirements\n- Limited budgets\n- Multiple departments with different priorities\n- Fragmented purchasing authority\n- Significant implementation constraints\n\n### Reimbursement uncertainty\n\nEven if a product improves care, there may not be a clear reimbursement pathway. If the economic benefit cannot be captured by the buyer, adoption may be slow.\n\n### Adoption and trust\n\nClinicians may resist systems that:\n\n- Increase verification work\n- Interrupt workflows\n- Produce inconsistent outputs\n- Fail to explain recommendations\n- Threaten professional autonomy\n- Add legal exposure\n\nTrust must be earned through usability, transparency, validation, and reliable escalation—not merely marketing.\n\n---\n\n## 9. Defensibility strategy\n\nA sustainable advantage should be built around several reinforcing assets.\n\n### Proprietary clinical data\n\nThe company should seek access to high-quality, permissioned data that improves performance in a defined specialty or workflow.\n\n### Validated outcomes\n\nEvidence of improved performance is more defensible than model architecture alone. Valuable evidence could include:\n\n- Clinician time saved\n- Denial-rate reduction\n- Diagnostic sensitivity\n- Reduced cost per encounter\n- Faster turnaround time\n- Improved trial enrollment\n- Fewer missed appointments\n- Better documentation completeness\n\n### Workflow integration\n\nDeep integration with EHRs, imaging systems, laboratories, payer systems, or clinical software can create switching costs.\n\n### Specialty-specific models\n\nSpecialty-specific systems can outperform horizontal tools in terminology, workflow, documentation, and clinical context.\n\n### Distribution partnerships\n\nPartnerships with EHR vendors, health systems, payers, specialty platforms, or established software vendors can create a durable route to market.\n\n### Regulatory and compliance capability\n\nA strong quality, privacy, security, and regulatory infrastructure can itself become a competitive advantage, especially as customers become more sophisticated.\n\n### Longitudinal monitoring\n\nDemonstrating reliable performance across time, sites, demographic groups, and model updates can create trust and make replacement more difficult.\n\n---\n\n## 10. Metrics that should determine product-market fit\n\nThe company should define success metrics before commercial deployment.\n\n### Operational metrics\n\n- Clinician time saved\n- Documentation completion time\n- Call-handling time\n- Authorization turnaround time\n- Coding productivity\n- Cost per encounter\n- Staff workload\n- Appointment completion rate\n\n### Financial metrics\n\n- Denial-rate reduction\n- Revenue recovered\n- Cost reduction\n- Return on investment\n- Customer acquisition cost\n- Payback period\n- Expansion revenue\n- Gross margin after inference and implementation costs\n\n### Clinical metrics\n\n- Diagnostic sensitivity and specificity\n- False-positive and false-negative rates\n- Calibration\n- Time to diagnosis\n- Adherence to care pathways\n- Patient safety events\n- Escalation accuracy\n- Performance across demographic and clinical subgroups\n\n### Adoption and trust metrics\n\n- Active-user rate\n- Percentage of AI outputs accepted without major edits\n- Override rate\n- Escalation rate\n- Clinician satisfaction\n- Patient satisfaction\n- Renewal and expansion rates\n\nA product should not be judged solely on model accuracy. Commercial viability depends on whether it improves a real workflow, achieves acceptable safety, integrates with existing systems, and generates economic value for the buyer.\n\n---\n\n## 11. Staged market-entry plan\n\n### Stage 1: Select a lower-risk, high-value use case\n\nPrioritize administrative or workflow automation rather than autonomous clinical decisions.\n\nGood initial candidates include:\n\n- Ambient clinical documentation\n- Prior-authorization automation\n- Coding and billing\n- Revenue-cycle management\n- Call-center copilots\n- Care navigation\n- Clinical-trial recruitment\n\n### Stage 2: Define the buyer and value proposition\n\nIdentify whether the buyer is:\n\n- A health-system executive\n- A chief medical information officer\n- A revenue-cycle leader\n- A payer\n- A specialty-practice administrator\n- A pharmaceutical company\n- A research organization\n\nThe product should have one primary economic buyer and a quantifiable business case.\n\n### Stage 3: Establish design partnerships\n\nWork with one or two health systems or specialty organizations to test:\n\n- Workflow fit\n- Data quality\n- Interoperability\n- Clinician usability\n- Security\n- Safety\n- ROI\n\n### Stage 4: Implement human oversight\n\nUse explicit human review, escalation, and approval mechanisms. The system should record:\n\n- Input data\n- Model version\n- Output\n- Human edits\n- Final decision\n- Escalations\n- Incidents\n\n### Stage 5: Validate externally and prospectively\n\nTest performance across different sites, patient populations, workflows, and equipment configurations. Include subgroup and fairness analysis.\n\n### Stage 6: Build the compliance and security foundation\n\nPrepare:\n\n- Privacy controls\n- Security assessments\n- Access management\n- Audit trails\n- Model-change controls\n- Quality processes\n- Regulatory documentation\n- Incident-response procedures\n\n### Stage 7: Expand through distribution partners\n\nAfter demonstrating repeatable value, pursue partnerships with:\n\n- EHR vendors\n- Clinical software providers\n- Specialty-care platforms\n- Payers\n- Health systems\n- Medical-device companies\n- Pharmaceutical or research organizations\n\n### Stage 8: Move toward higher-risk clinical applications selectively\n\nOnly expand into diagnosis, triage, or treatment support after establishing:\n\n- Sufficient validation\n- Regulatory approval or clearance where required\n- Reimbursement alignment\n- Clinician trust\n- Post-market monitoring\n- A robust liability and risk-management framework\n\n---\n\n## 12. Overall market-entry judgment\n\nThe AI healthcare market is attractive, with strong growth and multiple large spending pools. However, success depends less on model novelty than on execution in five areas:\n\n1. **Regulatory readiness**\n2. **Clinical evidence**\n3. **Interoperability**\n4. **Reimbursement and economic value**\n5. **Trust and workflow adoption**\n\nThe most practical entry strategy is to avoid an undifferentiated “AI assistant” product and instead target a specific, high-value workflow with a clear economic buyer and measurable ROI.\n\nThe strongest initial thesis would be:\n\n> Build a focused, human-in-the-loop AI product for a costly healthcare workflow, integrate it deeply into existing systems, validate its safety and financial impact with one or two design partners, and scale through established distribution channels.\n\nOpportunities exist in administrative burden reduction, diagnostic workflow support, chronic-care management, and drug development. Nevertheless, a staged approach is essential. The company should validate one use case in one care setting, establish measurable safety and ROI, obtain any required approvals, and expand only after repeatable adoption and monitoring capabilities have been demonstrated.", + "metadata" : { + "messageType" : "ASSISTANT" + }, + "toolCalls" : [ ], + "media" : [ ] + }, + "metadata" : { + "finishReason" : "STOP", + "contentFilters" : [ ], + "properties" : { } + } + } ] + } +} diff --git a/llm-recordings/66_handoff_to_parallel/6_93523f99-f2c9-46ac-a1b1-4052dc072d2a.json b/llm-recordings/66_handoff_to_parallel/6_93523f99-f2c9-46ac-a1b1-4052dc072d2a.json new file mode 100644 index 0000000000..9147711004 --- /dev/null +++ b/llm-recordings/66_handoff_to_parallel/6_93523f99-f2c9-46ac-a1b1-4052dc072d2a.json @@ -0,0 +1,64 @@ +{ + "schemaVersion" : 3, + "request" : { + "messages" : [ { + "role" : "system", + "text" : "You are a business strategist.
