Use codex credential in claude code

[ducan-ne]

Is it possible to use codex model in claude code? The documentation is not clear about this

@ducan-ne, it's possible. However, the current version doesn't fully support this. I plan to check it out tonight myself. Basically, right now, I only expose the Codex API's /response endpoint, similar to Claude.

I have an adapter for /chat/completions, but I'm thinking I could also create a similar adapter for the /messages endpoint found in Anthropic's API.

The big issue is that Codex's authentication prompt is pretty big and we can't truncate it like we can with Claude Code. This means it's going to pollute the context with bad instructions.

I'll definitely give it a shot!

Made some good progress on it in dev/v0.2, but it's currently not working. The OpenAI backend is returning an internal error, which makes it more difficult to pinpoint where in the request translation I made an error.
