What problem does it solve? Code reviews that only skim a diff miss the bugs that live in surrounding context, and reviews padded with vague nits waste everyone's time. This Skill makes you read the full files behind a change, verify every finding against real code, and post one consolidated GitHub review with comments anchored to exact diff lines. ## Core Features & Use Cases - Context-first review: Fetches the PR head ref and reads whole files, callers, and contracts beyond the diff hunks before forming any finding. - Verified, ranked findings: Every comment must name a concrete failure with specific inputs, and findings are split into fix-before-merge versus optional. - Correct GitHub review posting: Builds a single review JSON with commit_id, line anchors validated against the diff, and the right event (COMMENT on your own PRs, APPROVE or REQUEST_CHANGES on others), then verifies every comment landed. - Use Case: Before merging a substantial PR, ask for an honest review — you get one GitHub review where each comment cites the exact line, the concrete failure scenario, and a suggested fix, plus an explicit note on what was not verified. ## Quick Start Review PR number 42 honestly and leave a line-commented review on GitHub.
