Yes, this was made clear a while back and should not be a surprise. (Honestly, I had to double-check the date/time to see if this was actually posted today.

You can use your Claude Code subscription with third-party tools, but you have to use the Claude Code harness. Or, you use the API. OpenClaw could use the Claude Code harness, but they don't.

FWIW I am sympathetic to Anthropic here, but OpenClaw _is_ using the Claude Code harness (via claude -p). But yes, Anthropic has made it clear they don’t like this.

So they changed it? Last I heard they hadn't. Where did they announce they were switching to the Claude harness? I can't find anything.

I received the email and I have been using “Option B”, which wraps the Claude CLI. https://docs.openclaw.ai/providers/anthropic#option-b-claude...
