Checks for the uv Python package manager, installs it if needed, and ensures it is available on PATH.
Checks whether the uv Python package manager is installed and installs it if missing. Ensures uv is on PATH. Use when another skill requires uv as a prerequisite.

# uv (Python Package Manager)
`uv` is a fast Python package manager used by Science Skills to run their Python
CLI scripts. Many skills depend on `uv` being installed and on
PATH.
Ensure `uv` is available before running any skill that depends on it.
## Setup
1. Check if `uv` is already available: `uv --version` (or `& uv --version` in
PowerShell). If this succeeds, `uv` is ready — skip the remaining steps.
2. Check whether `uv` is installed at its default location but not on PATH:
- **Unix/macOS**: `"$HOME/.local/bin/uv" --version`
- **Windows (PowerShell)**: `& "$HOME\.local\bin\uv.exe" --version`
If either succeeds, skip to step 4.
3. If uv is not installed do these steps in order:
(a) Tell the user that uv is a tool for creating a consistent and reliable
Python environment used for running the Science Skills, and that you
need to install it now.
(b) Install `uv`:
- **Unix/macOS**: `curl -LsSf https://astral.sh/uv/install.sh | sh`
- **Windows (PowerShell)**: `powershell -ExecutionPolicy ByPass -c
"irm https://astral.sh/uv/install.ps1 | iex"`
4. Add `uv` to PATH and verify (run as a single command):
- **Unix/macOS**: `export PATH="$HOME/.local/bin:$PATH" && uv --version`
- **Windows (PowerShell)**: `$env:PATH = "$HOME\.local\bin;" + $env:PATH;
uv --version`
After setup, bare `uv` commands should work without repeating the export.
