How does this help with publishing to PyPI?

It provides standardized workflows for building distributions with the 'build' module and securely uploading them using Twine and API tokens.

Can I use this to create command-line tools?

Absolutely. The skill includes specific patterns for defining 'project.scripts' in your configuration to automatically create executable commands upon installation.

What is the recommended project layout for Python packages?

The 'src' layout is recommended as it prevents accidental imports from the root directory and ensures that tests are run against the actual installed version of the package.

Does this skill support modern build backends?

Yes, it covers modern PEP 517/518 compliant backends including setuptools, hatch, flit, and poetry for flexible building.
