"""
List every recipe (UV script) in the `uv-scripts` Hugging Face org.

The zero-setup way to see what's available: this script asks the Hub for every
dataset repo under the org, finds the `.py` scripts in each, and prints a runnable
URL for every one. No GPU, no token, no account needed — it only reads public repos.

Run it locally (nothing to install but uv itself):

    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/list-recipes.py

Add --describe to also print the first line of each script's docstring (slower —
it fetches each file):

    uv run https://huggingface.co/.../list-recipes.py --describe
