How do you even write a harness that can use a Claude subscription? I thought it was not allowed by Anthropic's ToS and can get you banned?

Amp recently achieved it. Apparently it's permitted as long as you use the Claude Agent SDK. https://ampcode.com/news/use-your-claude-plan

It's trivial to bypass this by tweaking the system prompt in other harnesses. They use string matching and a blacklist.

(Whether that's against the ToS is not clear.)

That’s a different discussion.

If you're using the sub, only OpenAI (via the OAuth token) is viable. Claude is API_KEY only

It's allowed, but you get bumped to per token pricing.
