What problem does it solve? Manual code reviews often miss critical issues like SQL injection, race conditions, or N+1 queries while wasting time on style nits that linters already catch. This Skill provides a structured, severity-ranked review process that focuses on what actually breaks production. ## Core Features & Use Cases - Four-dimension review: Audits security (injection, auth, secrets), correctness (edge cases, concurrency), performance (N+1 queries, missing indexes), and maintainability (dead code, test coverage). - Severity-ranked output: Classifies findings as Blocker, Major, Minor, or Nit with concrete failure scenarios and suggested fixes, producing a clear approve/request-changes verdict. - Use Case: Before merging a pull request, ask for a review of the branch diff. The Skill inspects each change in context, flags a missing webhook signature check as a Blocker with a fix snippet, and approves the rest. ## Quick Start Review the staged changes in this repository and report any security or performance issues with severity rankings.
