I had the same question on this. I did install the cli client as @stevenobird suggested but it is wanting me to login with an Anthropic account. Jeffrey made it sound like it came included with the Jetbrains AI subscription. As far as I can tell, you can't use your Jetbrains AI subscription with the Claude code CLI tool. I'm guessing that he has a separate Anthropic account that he's using with the CLI.

This is pretty awesome! It should work pretty well for my personal projects where I'm using Herd. I'm wondering though what you would have to do to make it work if your local environment is running in Docker?
