What makes this skill different from standard coding assistance?

This skill focuses specifically on the high-level architectural perspective of library design, emphasizing long-term maintainability, API stability, and package structure rather than just individual function implementations.

Does this skill help with PEP compliance?

Yes, it references and enforces critical standards like PEP 8 (Style), PEP 484 (Type Hints), and PEP 621 (Project Metadata) to ensure your library meets professional ecosystem standards.

Can I use this for existing projects?

Absolutely. It is designed to perform architectural audits of existing codebases, helping identify design bottlenecks, lack of type safety, or inconsistent API patterns.

What project structures does it recommend?

It advocates for the modern 'src/' layout and provides templates for production-ready pyproject.toml files, ensuring your library is compatible with modern build tools like Hatch, Poetry, and Flit.
