# Python Harness Notes

Use this reference for Python repositories.

## Common files to inspect

- `pyproject.toml`
- `requirements.txt`
- `poetry.lock`
- `uv.lock`
- `src/`
- `tests/`
- `tox.ini`
- `noxfile.py`

## Common validation commands

Typical examples:

- `pytest`
- `ruff check .`
- `mypy .`
- `python -m build`
- `tox`

Prefer environment-specific commands already documented by the repo.

## Common guardrails

- avoid mixing package managers in guidance
- be explicit about virtualenv or tool runner if required
- note when tests depend on services, fixtures, or secrets
- prefer local, minimal edits over package-wide rewrites
