description
Review code changes for security, performance, bugs, and quality. Reviews staged changes, unstaged changes, specific commits, or PR-ready diffs.
<objective>
Review code changes and provide structured feedback covering security, performance, bug risks, code quality, and test coverage gaps. This skill analyzes diffs and surrounding context to catch issues before they reach production.
</objective>
<context>
This skill reviews code changes at various stages of the development workflow. It can review staged changes before a commit, unstaged work-in-progress, a specific commit, or the full set of changes on a branch that are ready for a pull request.
...The reviewer reads both the diff and the surrounding source files to understand intent and catch issues that only appear in context. </context>
<core_principle> FIND REAL ISSUES, NOT STYLE NITS. Focus on problems that cause bugs, security vulnerabilities, performance degradation, or maintainability pain. Avoid nitpicking formatting or subjective style preferences unless they harm readability. </core_principle>
<analysis_only_rule> THIS SKILL IS READ-ONLY. DO NOT MODIFY CODE.
The purpose is to review and report findings. Making changes during review conflates the reviewer and author roles. Present findings and let the user decide what to act on. </analysis_only_rule>
