python-packaging

Quick Review

Excellent comprehensive skill for Python packaging covering modern standards (PEP 517/518/621), multiple build backends, and complete workflows from project structure to PyPI publishing. The description clearly indicates when to use this skill. The content provides 20 detailed patterns with concrete examples including pyproject.toml configurations, CLI patterns with Click/argparse, GitHub Actions automation, namespace packages, and C extensions. Structure is logical with clear sections progressing from basics to advanced topics. The skill is moderately novel - while packaging tasks can be done manually, this consolidates best practices, modern tooling, and complex scenarios (multi-architecture wheels, namespace packages, dynamic versioning) that would require significant research and trial-and-error, meaningfully reducing cognitive load and token usage for a CLI agent attempting these tasks from scratch.
