Add support for declarative tool installations (e.g., like Brewfile)

[michaeltinsley]

Summary

It would be great if uv had a way to store all installed tool installations into a standard file, similar to a homebrew brewfile.

My use case is I want to have tools installed with uv tool install ... added to a config file that I can track in git along with my brew installed libs in a brewfile, and my other dotfiles.

Yeah; this is on the roadmap, though it's not a high priority right now.

@michaeltinsley Would you be okay with using pyproject.toml for this (see my near duplicate at #13268) or do you need to keep this separate from any project?

[michaeltinsley]

@itcarroll - I think a pyproject.toml would work for my use case. I could dump that in ~/.config/uv/pyproject.toml.

For my ideal workflow, I would have something like:

# ~/.config/uv/pyproject.toml
[dependency-groups]
tools = [
    "ruff",
]

which would give something like:

> uv tool list
ruff v0.11.8
- ruff

Then if I do uv tool add black, it would automatically add it

> cat ~/.config/uv/pyproject.toml
...
[dependency-groups]
tools = [
    "ruff",
    "black",
]

That would be my ideal flow - I guess I'm more interested in uv tool add ... being automatically persisted to a file than anything, if that makes sense
