Hatchling

Overview

Hatchling is a modern, standards-compliant Python build backend that replaces legacy setuptools for package building. It provides clear configuration through pyproject.toml, intelligent defaults, and extensibility through hooks and plugins. This skill enables understanding Hatchling's architecture, configuration options, and build customization capabilities.
