The file path in the diff is relative to the repo root, not the current subdirectory.

I have a monorepo. If I !git diff in a project subdirectory then prompt, codex gets the paths wrong

The file path in the diff is relative to the repo root, not the current subdirectory. I’m reading the file from the correct location now.

Any workarounds?

!git diff --relative

You are hitting a path-base mismatch between the diff output and the current subdirectory context.

A reliable pattern is to make Git emit paths relative to your current folder:

!git diff --relative
!git diff --cached --relative

If you want to keep this ergonomic, an alias also works well:

git config alias.cdxdiff 'diff --relative'

Then in Codex:

!git cdxdiff

If you need a custom base, you can also do:

!git diff --relative="$(git rev-parse --show-prefix)"

That keeps file paths aligned with the folder you are currently working in.
