Review Checklist
1. Code Quality
- • Clear naming conventions
- • Single responsibility principle
- • DRY (Don't Repeat Yourself)
- • Appropriate abstraction level
- • Error handling completeness
- • Edge case coverage
2. Security
- • Input validation
- • SQL injection prevention
- • XSS prevention
- • Authentication/Authorization
- • Sensitive data exposure
- • Dependency vulnerabilities
3. Performance
- • Algorithm complexity (Big O)
- • Memory usage
- • Database query optimization
- • Caching opportunities
- • Async/await usage
- • Resource cleanup
4. Maintainability
- • Code readability
- • Comment quality (why, not what)
- • Test coverage
- • Documentation
- • Consistent formatting
Review Workflow
Step 1: Scope Understanding
bash
# Get changed files (if git)
git diff --name-only HEAD~1
# Or review specific files
Glob: src/**/*.{ts,js,py,cs}
Step 2: Critical Path First
- •Entry points and public APIs
- •Security-sensitive code (auth, data handling)
- •Business logic core
- •Utility functions
Step 3: Pattern Detection
bash
# Security issues Grep: "eval\(|innerHTML|dangerouslySetInnerHTML" Grep: "SELECT.*\+|INSERT.*\+" # SQL injection risk Grep: "password|secret|key|token" -i # Sensitive data # Performance issues Grep: "for.*for|while.*while" # Nested loops Grep: "\.forEach\(.*\.forEach" # Nested iterations # Code smells Grep: "TODO|FIXME|HACK|XXX" Grep: "console\.log|print\(|System\.out" # Debug code

## Code Review Report ### Summary | Category | Score | Issues | |----------|-------|--------| | Quality | 8/10 | 3 | | Security | 9/10 | 1 | | Performance | 7/10 | 2 | | Maintainability | 8/10 | 2 | ### Critical Issues 1. **[SECURITY]** `src/auth.ts:45` - Issue: Hardcoded API key - Fix: Use environment variables ```typescript // Before const API_KEY = "abc123"; // After const API_KEY = process.env.API_KEY;
Warnings
- •[PERFORMANCE]
src/utils.ts:120- •Issue: O(n^2) complexity in nested loop
- •Suggestion: Use Map for O(n) lookup
Suggestions
- •[QUALITY]
src/handlers.ts:30- •Add error handling for async operation
Good Practices Found
- •Consistent naming conventions
- •Good test coverage (85%)
- •Clear separation of concerns
