What problem does it solve? Code reviews often miss critical issues, produce vague feedback without file references, or drown reviewers in low-confidence noise. This Skill enforces a systematic review methodology so every change is checked consistently across four quality dimensions before merge. ## Core Features & Use Cases - Four-Layer Analysis: Systematically checks correctness, security, performance, and style/maintainability for every file in scope. - Severity Classification: Categorizes findings as Critical, Major, Minor, or Nitpick with clear action requirements for each level. - Confidence Thresholding: Only reports findings at 80% confidence or higher, explicitly flagging uncertain observations to reduce false positives. - Use Case: Before merging a pull request that touches authentication logic, run this review to catch hardcoded secrets, missing input validation, and N+1 query patterns, receiving a structured report with file:line references and an APPROVE or REQUEST_CHANGES verdict. ## Quick Start Review the changes in my current branch using the code-review methodology and report any critical or major issues with file and line references.
