Codex - Using Tabs vs. Spaces

I :heart: Codex, but have run into a single problem that I just can’t seem to prompt around.

Specifically, I am working in a codebase that uses tabs and not spaces. No matter what I put in the AGENTS.md file or the other markdown documentation, it just refuses to use tabs instead of spaces. I put it in multiple places. I used asterisks. I’ve used capitals and it still won’t default to tabs.

When providing feedback on each PR, I can often have it fix the mistake while I point to the code styling documentation, so it definitely knows how to do it, but even then it sometimes misses places.

I’m at a loss. Any tips from others in similar codebases?
