Skill: Python Project Operations

Use this skill when changing dependencies, running tests, linting, formatting, type checking, or executing notebooks.

Package Manager: uv Only

  • Use uv for all dependency installation, synchronization, addition, removal, and updates.
  • Never use pip, pip3, python -m pip, poetry, conda, pipenv, or easy_install.
  • Never manually create or edit requirements.txt.
  • Use uv add <package> when adding dependencies.
  • Use uv add --group dev <package> for dev-only dependencies.
  • Review diffs in pyproject.toml and uv.lock after dependency changes.

Python Version

  • Python 3.11.

Common Commands

uv sync                    # Install/synchronize dependencies
uv run pytest              # Run tests
uv run ruff check .        # Lint
uv run ruff format .       # Format
uv run mypy src            # Type check
uv run papermill notebooks/input.ipynb notebooks/output.ipynb  # Execute notebook
bash scripts/run_quality_checks.sh  # Run all quality checks

Workflow

  1. After modifying pyproject.toml, run uv sync.
  2. After adding code, run uv run ruff check . and uv run ruff format ..
  3. Before committing, run uv run pytest and uv run mypy src.
  4. For notebook execution in CI or automation, prefer papermill.

Tests and Tool Configuration

  • Place tests under tests/; keep them fast by minimizing external dependencies.
  • ruff settings live in the [tool.ruff] section of pyproject.toml.
  • mypy settings live in the [tool.mypy] section of pyproject.toml.
  • Verify notebooks re-run from a clean kernel — see notebook-workflow skill.

Validation Scripts

These run in GitHub Actions CI, and can be run locally before committing.

uv run python scripts/check_no_raw_data_commit.py    # rawデータのコミットを検知
uv run python scripts/check_no_sensitive_patterns.py # 秘密情報のパターンを検知
uv run python scripts/validate_agent_docs.py         # エージェント文書の必須ファイル確認
uv run python scripts/sync_agent_docs.py --check     # CLAUDE.md / AGENTS.md のドリフト検出
bash scripts/run_quality_checks.sh                   # 上記を含む一括実行
