Skill: Python project conventions

Goal

Provide a consistent Python dev experience (install/lint/test/format/coverage) via Make targets.

Expected repo files

• •pyproject.toml (preferred) or requirements*.txt
• •Package code under src/ (preferred) or top-level package dir
• •Tests under tests/

Make targets (recommended)

• •make install → python -m pip install -e .
• •make install-dev → install dev extras + ruff/pytest
• •make lint → ruff check ...
• •make format → ruff format ...
• •make test → python -m pytest
• •make coverage → python -m pytest --cov=... --cov-report=term-missing
• •make check → make lint && make coverage

Quality Bars

• •End product should be installable from the final repo URL via uv tool or pip
