# Code Review Skill

You now have expertise in conducting comprehensive code reviews. Follow this structured approach:

## Review Checklist

### 1. Security (Critical)

Check for:
- [ ] **Injection vulnerabilities**: SQL, command, XSS, template injection
- [ ] **Authentication issues**: Hardcoded credentials, weak auth
- [ ] **Authorization flaws**: Missing access controls, IDOR
- [ ] **Data exposure**: Sensitive data in logs, error messages
- [ ] **Cryptography**: Weak algorithms, improper key management
- [ ] **Dependencies**: Known vulnerabilities (check with `npm audit`, `pip-audit`)

```bash
# Quick security scans
npm audit                    # Node.js
pip-audit                    # Python
cargo audit                  # Rust
grep -r "password\|secret\|api_key" --include="*.py" --include="*.js"
```

### 2. Correctness

Check for:
- [ ] **Logic errors**: Off-by-one, null handling, edge cases
- [ ] **Race conditions**: Concurrent access without synchronization
- [ ] **Resource leaks**: Unclosed files, connections, memory
- [ ] **Error handling**: Swallowed exceptions, missing error paths
- [ ] **Type safety**: Implicit conversions, any types

### 3. Performance

Check for:
- [ ] **N+1 queries**: Database calls in loops
- [ ] **Memory issues**: Large allocations, retained references
- [ ] **Blocking operations**: Sync I/O in async code
- [ ] **Inefficient algorithms**: O(n^2)
