Python Project Development (Lean)

Use this skill when

• creating Python CLIs or packages
• setting up pyproject.toml
• preparing build/publish workflows
• tightening packaging, linting, and test gates

Defaults

• Prefer uv for dependency and run workflows.
• Keep package layout src/<package_name>/.
• Use typed function signatures and explicit exit codes.
• Treat ruff + tests as baseline quality gates.
