It worth noting that – just to add to the confusion – they apparently cancelled the June 15th change just before it was due to go live: https://support.claude.com/en/articles/15036540-use-the-clau... https://the-decoder.com/anthropic-backs-off-unpopular-billin... So... maybe we can still use third party harnesses with Claude Code subscriptions... for now? Until they change their mind again?
> So... maybe we can still use third party harnesses with Claude Code subscriptions... for now? The way I read this is: yes, if the third party harness uses Anthropic's Agent SDK. Most of them do not, AFAIK, and are still against ToS (though maybe its not enforced for now)
So this wasn't even about third-party harnesses that replace the toolset Claude has access to, and try to call the Claude API with subsidized credentials. No, this was literally a blessing for their desktop UI's over others, all driving Claude Code's CLI at the end of the day.
To the broader point, it's hard not to see that as arbitrary and borderline spyware. Software that sniffs the context in which it's executed and uses that to phone home about billing is the type of thing you'd expect from the most corporate parts of the gaming industry, not a frontier lab, but here we are.
