If you put ANTHROPIC_API_KEY in the cloud environment, this will cause CC to fail to do anything.

So you were using it because your tests are going to look for it, think again, find another way.

Also, I suspect that is why I had a lot of "Extra usage".

For the whole long history:

Hope this saves some others a lot of headaches!
