This is a structured PR review tool that reads diff and description files from your local checkout, analyzes the changes, and writes machine-readable feedback to review.json instead of posting directly to GitHub. It's built for CI workflows where you want Claude to review code but need the output in a specific JSON shape for another step to handle publishing. The prompt is opinionated about what matters: it prioritizes correctness and security, avoids nitpicking unless it can offer concrete fixes, and labels every comment as critical, important, suggestion, or nit. The diff annotation format with OLD/NEW line markers is smart but adds learning overhead. If you're wiring Claude into a review pipeline and need deterministic output rather than conversational feedback, this gives you the guardrails.
