Uh, isn't that the regular Claude code extension that's been available for ages at this point? Not jetbrains but anthropics own development?

As a person paying for the jetbrains ultimate package (all ides), I think going with vscode is a very solid decision.

The jetbrains ides still have various features which I always miss whenever I need to use another IDE (like way better "import" suggestions as an easy to understand example)... But unless you're writing in specific languages like Java, vscode is way quicker and works just fine - and that applies even more to agentic development, where you're using these features less and less...
