claude-python-plugin 0.1.0

Claude Code plugin: ruff + mypy + pytest + uv hooks and Python skills.

python-plugin

Claude Code plugin that wires the modern Python toolchain into every agent session: ruff for lint + format, mypy for strict static types, uv for envs and lockfile, pytest for related-test execution, and a missing-test warning for new modules.

Ships:

• Hooks (PostToolUse after Edit | Write | MultiEdit):
  • posttooluse-ruff — ruff check + ruff format --check on edited .py.
  • posttooluse-mypy — type-check edited .py against the project's mypy config.
  • posttooluse-pytest — run pytest tests related to edited .py (companion test_<name>.py discovery; falls back to --lf).
  • posttouse-test-required — warn on new non-test .py without a sibling test_<name>.py.
  • posttooluse-uv-lock — re-lock pyproject.toml changes via uv lock.
• Skills:
  • python — unified Python coding standard (load on any .py interaction).
  • python-ruff, python-mypy, python-uv, python-pytest, python-pypi — per-tool deep dives for fine-grained enablement.

Install

Add to your Claude Code marketplace plugins, or symlink the repo into ~/.claude/plugins/.

Per-shell toggles

Each hook honors a PYTHON_PLUGIN_<NAME>=0 env var to disable it:

• PYTHON_PLUGIN_RUFF
• PYTHON_PLUGIN_MYPY
• PYTHON_PLUGIN_PYTEST
• PYTHON_PLUGIN_REQUIRE_TESTS
• PYTHON_PLUGIN_UV_LOCK

Requirements

• python3 on PATH (3.11+).
• One of ruff, mypy, pytest, uv available — either project-local in .venv/bin/, globally installed, or invocable via uvx. Hooks skip silently when their tool isn't reachable; CI is the source of truth.
