I don't think there's any ToS violation involved? AIUI you can use GPT models with any harness, at least at present.

You could nonetheless have Codex write up the plan to an .md file for Claude (perhaps Sonnet or even Haiku?) to execute.

I meant with the subscriptions, which are heavily subsidized. API billing is free game.

Anthropic's been against 3rd party usage of the subs, including, I believe, 3rd party software invoking Claude Code.

OpenAI, from what I heard, is the only company tolerating this type of usage (for now).

So my point was, if you get a subscription from both, you could let Claude "drive" Codex, but not the reverse.

And while it sounds silly, it might actually be the only way to get real work done at the moment, with usage being exhausted so quickly.
