Code Review
Review code for quality, security, and maintainability.
When to Use This Skill
Use this skill:
- After code changes are completed and ready for review
- Before staging changes for commit
- As a proactive quality check during development
Context
When invoked, examine:
- Current git status:
git status
- Current git diff (staged and unstaged changes):
git diff --no-ext-diff HEAD
- Current branch:
git branch --show-current
- Recent commits:
git log --oneline -40
Review Checklist
Examine all modified files and check:
- NO DUPLICATED CODE! - Extract common logic into reusable functions
- Functions 30 lines or shorter - Break down complex functions
- Well-named functions and variables - Clear, descriptive names
- Simple and readable code - Avoid unnecessary complexity
- Proper error handling - Handle edge cases and failures gracefully
- No exposed secrets or API keys - Use environment variables or config
- Input validation implemented - Validate all external inputs
- Good test coverage - Tests for critical paths
- Performance considerations - No obvious O(n²) or worse patterns
Feedback Organization
Provide feedback organized by priority:
- Critical issues (MUST FIX): Security vulnerabilities, bugs, broken functionality
- Warnings (SHOULD FIX): Code quality, maintainability concerns
- Suggestions (CONSIDER): Improvements that would be nice to have
For each issue, include:
- Specific location (file, line number)
- Description of the problem
- Example of how to fix it
Output
Provide a structured review:
## Critical Issues
- [File:line] Description of issue
- How to fix: ...
## Warnings
- [File:line] Description of concern
- Suggestion: ...
## Suggestions
- [File:line] Nice-to-have improvement
If no issues found: "Code review passed. No issues identified."
