I'm not entirely sure what the intended result for pre-commit is, but I think my host env is too dirtied at this point to replicate the original conditions. I:

• Ran make clean.
• Removed uv.
• Removed all references to uv from my bash scripts.
• Removed pre-commit from ~/.local/bin/.
• Removed pre-commit from .git/hooks/

When I ran which pre-commit, it yielded nothing.

Then, when I re-ran make setup, it replied with:

sudo snap install --classic astral-uv
astral-uv 0.5.7 from Alex Lowe (lengau) installed
uv tool install pre-commit
uv tool run pre-commit install
`pre-commit` is already installed
pre-commit installed at .git/hooks/pre-commit
uv sync --frozen --all-extras

Is the bit about "already installed" wrong? Should it be installing as a script in .git/hooks/? I thought it was installing a binary.

@medubelko pre-commit I think stores things elsewhere - try running pre-commit uninstall?

[medubelko]

pre-commit is completely absent from my system at this point, which is why I'm confused about why the log says I have it.

[lengau]

uv still had pre-commit installed as a tool, so I think it's fine.

Thank you!

Approving, but I'm not confident in my own testing of this.
