What problem does it solve? Merging pull requests without a structured review risks breaking the demo, violating API contracts, or letting scope creep slip into main. This Skill enforces a consistent six-gate review procedure so every PR is checked against its task card, contracts, and proof before merging. ## Core Features & Use Cases - Six-Gate Review: Checks card match, contract fidelity, proof of correctness, abstraction discipline, demo-path safety, and hygiene in a fixed order, stopping at the first failure. - Standardized Verdicts: Outputs a strict MERGE, FIX-THEN-MERGE, or BLOCK verdict with actionable file-and-line fixes and a normal/crunch bar setting. - Use Case: A reviewer opens a fresh session on a feature branch, reads the task card and touched contracts, runs the PR's check, and issues a verdict within 15 minutes — blocking a contract-breaking change before it reaches the demo. ## Quick Start Review the current pull request against its task card and contracts, then give me a MERGE, FIX-THEN-MERGE, or BLOCK verdict.
