Does it replace tools like Ruff or Mypy?

It complements them. The skill provides high-level architectural and logic reviews while recommending specific Ruff and Mypy commands to automate the fixing process.

How does it handle complex code structures?

It assesses cyclomatic complexity and nesting levels, suggesting refactoring patterns like replacing loops with comprehensions or using dataclasses to simplify objects.

Does this skill support the latest Python features?

Yes, it specifically focuses on modern best practices for Python 3.9 and above, including support for PEP 604 union types and PEP 585 generic collections.

Can I use this for library development as well as applications?

Absolutely. The skill adjusts its review approach based on whether you are writing application code or a public-facing library, emphasizing docstring quality for APIs.
