What's Wrong?

My buddy changed from a purple kitten into a white octopus.

What Should Happen?

He should still be a little purple kitten, and the description of buddy still retains the description of a kitten.

Steps to Reproduce

1. I generated a buddy earlier today through /buddy, which is a purple kitten.

1. Just now, the terminal prompted me to execute claude install, saying that I previously installed it via npm, and after upgrading, it would be more stable and faster, so I executed it.

1. Then my colorful little cat disappeared, give me back my kitten 🐱.😭😭😭
