Python UV Fails in Codex

1 month ago 5

What version of Codex is running?

codex-cli 0.2.0

Which model were you using?

codex-mini-latest

What platform is your computer?

Darwin 24.5.0 arm64 arm

What steps can reproduce the bug?

Start codex in environment using uv and tell it to run pre-commit or many other tools. All fail with sandbox violations.

What is the expected behavior?

uv runs normally

What do you see instead?

Not permitted errors, due to sandboxing restrictions

Additional information

I tried adding the ~/.cache/uv directory to writable roots, but it had no apparent effect.

This is similar to the issues I saw with NPM when on the fully YOLO mode, but I was able to avoid them using auto-edit mode there. In the rust version it seems that all modes produce the same sandboxing errors, making the tool functionally unusable in the present state.
