pyproject.toml Configuration Skill

Master pyproject.toml for modern Python project configuration, build systems, tool settings, and dependency management.

When to Use This Skill

Use pyproject.toml configuration when you need:

• Project metadata - Name, version, description, authors
• Dependency management - Core and optional dependencies
• Build configuration - Setuptools, hatch, flit, or poetry
• Tool configuration - pytest, ruff, mypy, black, isort
• Entry points - CLI scripts and plugins
• Package discovery - Source directory configuration

Avoid when:

• Legacy projects requiring setup.py (rare, migrate instead)
• Non-Python projects
