Can this skill help with asynchronous Python code?

Yes, it specifically highlights anti-patterns like using blocking calls (time.sleep or synchronous requests) within async functions, which can stall the event loop.

What kind of Python issues does this skill detect?

It identifies common mistakes across infrastructure (like double retries), architecture (like leaking ORM models), error handling (like bare exceptions), resource management, type safety, and testing.

Does it provide solutions or just identify problems?

The skill provides both the identification of the anti-pattern and the recommended 'Good' pattern or fix to implement, including code examples.

How does this differ from standard linters like Flake8 or Pylint?

While linters catch syntax and style, this skill focuses on higher-level architectural patterns, logic flaws, and design principles that automated tools often miss.

Security & Testing

Identifies and resolves common Python coding mistakes, architectural flaws, and performance bottlenecks using a comprehensive best-practices checklist.

This skill serves as an automated code reviewer for Python projects, helping developers identify and resolve common anti-patterns before they reach production. It covers critical areas such as infrastructure retry logic, architectural boundary leaks, resource management, and type safety. By integrating this skill into the development workflow, teams can ensure consistent coding standards, improve system reliability, and reduce technical debt through proactive identification of known bad practices like bare exception handling, hard-coded configurations, or blocking calls in asynchronous code.
