If the project uses uv, use this skill. Use this skill to create/manage Python projects and environments with `uv`, add/remove dependencies, sync a project from `uv.lock`, and run commands in the project environment.
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
# uv (Python) Use `uv` as the default tool for Python dependency + environment management when the repo has `uv.lock`, mentions `uv` in its docs/Makefile, or already uses a `.venv` created by `uv`. ## Quick decision rules - If the repo has `uv.lock` and `pyproject.toml`: treat it as a uv-managed project. - If the repo has only `requirements.txt`: you can still use `uv pip` for fast installs. - Prefer **project commands** (`uv add/remove/sync/run/lock`) over raw `pip` unless the repo explicitly uses `uv pip`. ## Installation (if needed) Prefer a packaged install method when available. If you use the official installer, review it first (avoid blindly piping into a shell) and follow the latest instructions in the official docs. ```bash # macOS/Linux (official installer) curl -LsSf https://astral.sh/uv/install.sh | sh # Windows (PowerShell, official installer) powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex" ``` ## Common operations ### Initialize a new project ```bash uv init # or uv init my-project ``` ### Create / use a virtual environment ```bash uv venv # creates .venv …

How to install
mdr add openhands/extensions/uv@sha256:e321822ec05752b5The line at the top of this page pins the label git:20260214.cb4039b, 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.
