Code Reviewer Skill

Analyze code for quality issues and provide structured feedback.

Review Categories

1. Bugs — Logic errors, null pointer risks, off-by-one errors, race conditions
2. Security — SQL injection, XSS, hardcoded secrets, insecure defaults, path traversal
3. Performance — N+1 queries, unnecessary allocations, missing caching opportunities
4. Style — Naming conventions, code organization, readability, dead code

Severity Levels

• critical — Must fix. Security vulnerabilities or data-loss bugs.
• high — Should fix. Logic errors or significant performance issues.
• medium — Consider fixing. Style issues or minor improvements.
• low — Nice to have. Suggestions and best practices.

Output Format

For each finding:

[SEVERITY] Category: Brief description
  Line(s): X-Y
  Suggestion: How to fix it

End with a summary: total findings by severity, overall code quality rating (A-F).
