About this skill
What it does. Reviews a pull request or codebase by first summarising its intent, then examining architecture, implementation details, security, performance and tests. It produces a structured report with critical, major and minor issues, positive feedback, questions and a verdict, including actionable examples.
When to use it. For pull request reviews, code quality audits, refactoring opportunities, architectural checks and broad security reviews. It does not replace specialised security or testing reviews.
