What's Wrong?

Hi,

I just installed Claude on VSCode and started learning how to use it. I tried using the /agents commands in the UI, and got told by the UI to configure agents in the Terminal window. No big deal, I get that the UI is new.
The problem is that, when I open a Claude Terminal, Claude doesn't work. The command claude (which to my understanding is automatically run upon opening a Claude terminal) returns bash: claude: command not found, and the claude commands (e.g. /agents do not work)

What Should Happen?

Claude should work in terminal mode on VSCode
