The workflow is split into two jobs for least-privilege: 1. 'review' job — runs Claude with read-only permissions (contents: read, id-token: write for AWS OIDC, actions: read). Claude produces a structured JSON review via --json-schema with a 'comments' array and a 'summary' string. Its tools are restricted to read-only operations (Read, LS, Grep, Glob, Task, and various Bash prefixes for common read-only commands). Claude also has access to CI MCP tools to analyze failed workflow runs. 2. 'post' job — only has pull-requests: write. Reads the structured JSON output from the review job and posts inline comments individually (so re-runs only add new comments). Maintains a tracking comment with a <!-- claude-pr-review --> marker that is created on first run and updated in-place on subsequent runs, preserving existing item order, wording, and checkbox state. Posts a notification comment when the tracking comment is updated or left unchanged. Comment deduplication is handled by Claude in the prompt rather than in the posting script, allowing for better semantic understanding of whether two comments address the same issue. The PR number is resolved via github.event.pull_request.number with a fallback to github.event.issue.number for issue_comment events where github.event.pull_request is not populated. The concurrency group uses the same fallback. Co-developed-by: Claude <claude@anthropic.com>
