What this skill does#

Use this skill to perform a structured Python code review. It should catch correctness bugs, edge cases, regressions, test gaps, security issues, and maintainability problems.

When to use#

• Reviewing a Python diff, patch, or pull request
• Checking a script before merging
• Auditing a change for risky behavior
• Summarizing review findings for a human

Review workflow#

1. Read the change and identify the intent.
2. Check correctness first:
   • logic errors
   • missing branches
   • off-by-one issues
   • null/empty handling
   • exception paths
3. Check safety:
   • command execution
   • file handling
   • input validation
   • secrets exposure
   • network or subprocess risks
4. Check tests:
   • existing coverage
   • missing regression tests
   • behavior under failure cases
5. Check maintainability:
   • naming
   • duplication
   • clarity
   • unnecessary complexity
6. Report only real issues. Do not invent problems.

Output format#

Prefer a concise review with:

• Overall verdict
• High-priority issues first
• File/line references when available
• Suggested fixes

Example:

• High: foo.py:42 — off-by-one in loop causes last item to be skipped.
• Medium: bar.py:18 — no timeout on network call.

Notes#

• Be specific.
• Be practical.
• If the change is fine, say so.
• If you cannot verify something, say what is missing.

Local helpers#

• scripts/review.py — core review logic
• scripts/review_runner.py — wrapper/runner for review execution
