what is the goal of these tools, having a hard timeunderstanding the value vs just running them on terminal
That is the value. You can run them remotely from your phone and set them up on a headless machine too. You’re not bound to your terminal.
My usual workflow is to still use the terminal for heavy work. But sometimes I just want to prompt from my phone and run a few tasks or do some planning. Then I can simply resume the session in the terminal later. It's the flexibility.
