What problem does it solve? Single-PR review misses integration failures that only appear when changes span multiple repositories, such as broken contracts between a shared library and its consumers, unsafe rollout ordering, or old/new version incompatibility across independently deployed components. ## Core Features & Use Cases - Contract Reconstruction: Builds or locates a cross-repo feature contract covering APIs, schemas, versions, publish order, and compatibility combinations, then reviews every PR against it. - Isolated Per-PR Inspection Plus Integration Synthesis: Inventories each PR separately (surfaces, dependencies, tests, CI) before synthesizing cross-repo blockers, per-PR blockers, follow-ups, and discarded noise. - Structured Verdict Report: Produces a severity-classified report with overall verdict, merge/rollout order, cross-repo and per-PR findings, test gaps, open questions, and checks run. - Use Case: A feature touches a core types package, a backend service, and a web UI across three repos. The skill reviews all three PRs together, catches that the UI assumes a backend field that only exists after a specific deploy order, and flags it as a cross-repo blocker with a suggested fix. ## Quick Start Ask the assistant to review these linked pull requests together as one cross-repo feature and paste the PR URLs for each affected repository.
