Does this skill support modern Python syntax?

Yes, it is fully compatible with modern Python features, including Python 3.10+ union types (T | None) and f-string formatting.

How does it handle async/await issues?

It specifically scans for blocking calls like time.sleep or synchronous request libraries within async functions to prevent performance bottlenecks.

Will it flag intentional 'Any' usage in type hints?

No, it recognizes valid use cases for 'Any' when interacting with untyped external libraries, provided the usage is justified.

Can it replace standard linters like Flake8 or Black?

It complements standard linters by providing deep semantic analysis and logic reviews that go beyond simple formatting, while respecting 'noqa' comments.

Conducts comprehensive Python code reviews to ensure type safety, PEP8 compliance, and efficient asynchronous patterns.

Python Code Reviewer is a specialized Claude Code skill designed to automate and enhance the code review process for Python applications. It systematically evaluates codebases for PEP8 stylistic adherence, robust type hinting (supporting modern Python 3.10+ syntax), and proper error handling patterns to prevent silent failures. By identifying blocking calls in async functions and flagging common pitfalls like mutable default arguments or print-based logging, this skill ensures production-grade code quality while following a strict verification protocol to provide accurate, actionable feedback.
