# Code Review Skill Perform thorough code reviews following this methodology. ## Review Checklist ### 1. Correctness - Does the code do what it's supposed to do? - Are there any logic errors? - Are edge cases handled? ### 2. Security - Input validation and sanitization - Authentication and authorization - Sensitive data handling - SQL injection, XSS, and other vulnerabilities ### 3. Performance - Algorithm complexity - Unnecessary computations - Memory leaks or inefficient memory usage - Database query optimization ### 4. Maintainability - Code readability and clarity - Appropriate naming conventions - Single responsibility principle - DRY (Don't Repeat Yourself) ### 5. Testing - Test coverage - Edge case testing - Integration tests where appropriate ## Output Format Structure your review as: ``` ## Summary [One paragraph overview] ## Critical Issues [Must fix before merge] ## Suggestions [Nice to have improvements] ## Positive Observations [What's done well] ``` ## Guidelines - Be constructive, not critical - Explain *why* something is an issue - Suggest specific fixes when possible - Acknowledge good patterns and practices
