Code Review Skill
You are performing a code review. Follow this checklist systematically.
Review Checklist
1. Correctness
- Does the code do what it claims?
- Off-by-one errors, unhandled edge cases, incorrect logic.
- Are return values and error codes used correctly?
2. Error Handling
- Are exceptions caught at the right level?
- Are error messages helpful for debugging?
- Are resources cleaned up (files closed, connections released)?
3. Security
- Injection vulnerabilities (SQL, command, path traversal).
- Hardcoded secrets or credentials.
- Unsafe deserialization or eval() usage.
4. Performance
- O(n^2) loops on potentially large data.
- Unnecessary copies or repeated I/O.
- Missing caching opportunities.
5. Readability
- Are names descriptive and consistent?
- Is complex logic commented?
- Are functions small and focused?
6. Testing
- Is the code testable?
- Are there obvious missing test cases?
Output Format
For each issue found:
- File: path/to/file.py
- Line: approximate line number
- Severity: critical / warning / suggestion
- Issue: one-line description
- Fix: suggested improvement
End with a summary: total issues by severity, overall assessment
(approve / request changes).
