+# Claude reviews
+
+Repository owners and members can request a pull request review by commenting
+`@claude`. The workflow uses `prompts/code-review.md` and posts the review as a
+pull request comment. Add instructions after `@claude` to use interactive mode
+with the triggering comment and conversation context instead.
+
+Reviews use Claude Sonnet 4.6 through the US cross-region Bedrock inference
+profile in `us-west-2`. Configure the model with the pinned action's
+`claude_args: --model` input; `anthropic_model` is not supported. The workflow
+has a ten-minute job timeout. The inference role must permit invocation of the
+profile and its destination models.
+
+Comment-triggered workflows use the default branch's workflow definition.
+End-to-end verification of workflow changes requires merging them before
+requesting another review.
