About
This skill reviews pull requests by analyzing code diffs against a base branch for correctness, test coverage, and documentation accuracy. It automatically examines changed code for edge cases, error handling, and tests for new logic. Use it when asked to review branches, diffs, or pull requests in development workflows.

Documentation
PR Review
Review the branch's change surface, not the whole repository.
- Establish the diff:
git diff <base>...HEAD(andgit diff <base>when the working tree carries uncommitted changes that belong to the branch). The base branch is named by the caller; fall back tomain. - Review every changed hunk for correctness: wrong results on edge inputs, unhandled error paths, and behavior that contradicts the function's name or callers.
- Check test coverage for the changed behavior: new logic without a test exercising its edge cases is a finding.
- Check documentation the diff made stale: statements in README or docs that were true on the base branch and are false after the change.
- Report every defect found, each with a severity; include minor and informational findings. Do not report defects in files the branch did not touch — they are outside the pull request.
