What problem does it solve?

This Skill solves the challenge of turning Python code into a well-structured, installable, and publishable package so users can reliably install it from PyPI (or private registries) instead of relying on ad-hoc setups.

Core Features & Use Cases

• Modern project configuration: Set up packaging metadata in pyproject.toml using PEP 517/518 (build system) and PEP 621 (project metadata).
• Correct distribution workflow: Build wheels and source distributions, then validate the artifacts before uploading to PyPI/TestPyPI/private indexes.
• CLI & extensibility patterns: Define command-line entry points (e.g., project.scripts) and support advanced patterns like namespace packages and versioning strategies.
• Use case examples: Create a library with a recommended src/ layout, publish it with proper classifiers and dependencies, and optionally expose a CLI tool that installs and runs via a single command.

Quick Start

Ask: “Create a minimal Python package using src layout and pyproject.toml for a new library named my-package with version 0.1.0, including required metadata, a basic dependency on requests, and a CLI entry point named my-tool.”
