Bug Description

I started using claude code and all went fine. Then suddenly it started to get very expensive. Even a short message like "hi" costs me 0.1 USD. I see it's using a lot of cache write, but i'm not sure if that is whats causing it. Asking it to install a cli tool with brew costed like 0.5 USD.
