What problem does it solve?

This Skill prevents noisy, unreliable Python PR feedback by systematically checking common high-impact Python 3.12/3.13 mistakes that linters may miss, especially around correctness, security, and runtime performance pitfalls in real diff changes.

Core Features & Use Cases

Anti-pattern checklist for Python reviewers: Covers mutable defaults, exception hygiene, value equality bugs, type-hint/runtime drift, asyncio blocking, and dataclass/class performance traps.
Security-focused checks: Flags risky constructs like pickle.loads on untrusted bytes, eval/exec on influenced input, insecure f-string SQL/shell composition, and outbound HTTP calls without timeouts.
Python-version-aware modern guidance: Includes 3.12/3.13-specific topics such as PEP 695 type aliases, @override, async generator cancellation, exception groups, and free-threaded build implications.

Quick Start

Ask the AI to run the Python review reference for a PR that modifies Python files and then return a bounded list of only the issues supported by quoted diff evidence.
