Python Packaging

Comprehensive guide to creating, structuring, and distributing Python packages using modern packaging tools, pyproject.toml, and publishing to PyPI.

Use this skill when

• Creating Python libraries for distribution
• Building command-line tools with entry points
• Publishing packages to PyPI or private repositories
• Setting up Python project structure
• Creating installable packages with dependencies
• Building wheels and source distributions
• Versioning and releasing Python packages
• Creating namespace packages
• Implementing package metadata and classifiers

Do not use this skill when

• The task is unrelated to python packaging
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.
