What's Wrong?

When I click options in VSCode extension "/" menu that ask to open the Terminal, the result is a new VSCode window is open, it hangs without at change for 1 or 2 seconds, it flashes with a command and a result that I can't read because it auto closes.

This happens for commands like Permissions...

Investigating it seems this is happening becayse Claude CLI is not installed.. but VSCode extension already comes with Claude...

So maybe the problem is that the PATH in windows 11 doesn't have the Claude that VSCode is using.. IDK

Either way.. it should not behave like that.. It should not auto-close, etc.

What Should Happen?

It should show the Permission or what ever the "/" Menu option was pressed in the UI
