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.
Key Capabilities
Consult ../python3-development/references/python3-standards.md when applying shared architecture, typing, testing, or CLI rules; full standards, graphs, and amendment process are documented there.
- Configuration via pyproject.toml: Standards-compliant PEP 621 metadata with sensible defaults
- Build Targets: Wheel and source distribution builds with extensive customization
- Build Hooks: Dynamic code execution during build for artifacts, version management, and compilation
- Version Management: Multiple version sources with automatic version injection
- File Selection: Git-aware VCS integration with glob pattern matching
- Plugins: Extensible architecture for custom builders, hooks, and metadata hooks

'--auto {title}': autonomous mode — no AskUserQuestion, derives data from research files, logs decisions. 'close {title}': dismiss without completion — reason required (duplicate, out_of_scope, superseded, wontfix, blocked). ADR-9. 'resolve {title}': mark DONE with evidence trail — summary required. ADR-9. 'setup-github': init labels, project, milestone. '--language' and '--stack' select Layer 1/2 profile. STOPS if item has Plan field or RT-ICA returns BLOCKED.
