Fast Python environment management with uv (10-100x faster than pip). Triggers on: uv, venv, pip, pyproject, python environment, install package, dependencies.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Environment Fast Python environment management with uv. Prefer the uv **project** workflow (`uv add` / `uv sync` / `uv run`) over the `uv pip` compatibility layer — it manages `pyproject.toml` + a lockfile for you and is reproducible. ## Quick Commands | Task | Command | |------|---------| | Start a project | `uv init <name>` (app) · `uv init --package <name>` (installable, `src/` layout) | | Add dependency | `uv add httpx` | | Add dev dependency | `uv add --dev pytest ruff` | | Remove dependency | `uv remove httpx` | | Sync env from lockfile | `uv sync` | | Run in project env | `uv run pytest` | | Update lockfile | `uv lock` | | Install a CLI tool | `uv tool install ruff` · one-shot: `uvx ruff` | | Install a Python | `uv python install 3.12` | ## Start a Project ```bash # Application (flat layout, no package build) uv init myapp # Installable package (src/ layout — separate tests/ that import by name) uv init --package wordtools # → src/wordtools/__init__.py, pyproject.toml with build-system ``` `uv init` creates `pyproject.toml`, pins a Python version, and prepares the project for `uv add` / `uv sync`. The `--package` (src) layout is preferred for …

How to install
mdr add 0xdarkmatter/claude-mods/python-env@sha256:3d541fb0623ffc58The line at the top of this page pins the label git:20260705.3e9869e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
