Does this skill support modern PEP 621 standards?

Yes, it prioritizes PEP 621 and PEP 517 standards by utilizing pyproject.toml for all metadata, build-system requirements, and project configurations.

Can I use this for private package repositories?

Absolutely. The skill includes patterns for configuring .pypirc and twine to work with private registries like JFrog, Artifactory, or AWS CodeArtifact.

Does it help with CLI tool development?

Yes, it provides specific implementation patterns for both Click and argparse, including the necessary entry-point registration in your project metadata.

Why use the src-layout instead of a flat layout?

The src-layout is recommended because it prevents accidental imports from the project root and ensures that your tests run against the installed package version.
