If they can't be bothered to make a requirements.txt file, I'm not seeing how uv will be of much help...

uv basically makes that a default. You don’t need to be bothered. Just uv add your dependencies and they are in your pyproject.toml.

Or use `uv add --script`. Then dependencies gets recorded in the script itself, which is great for single-file scripts. But obviously, that won't help if the author can't be bothered to take those steps
