What's Wrong?

This is concerning https://github.com/anthropics/claude-code/issues/1278 and related issues closed as not planned.

Claude code cli sneakily installs itself if I run from the vscode integrated terminal. There seems to be no way to disable this behaviour.
I think this is a grave user consent issue and should never happen anywhere.

What Should Happen?

Claude shouldn't ever self install a vscode extension without user consent.
