I thought I made it clear right up front. 'Why agents need their own CLI'

What's not clear about that?

Here's a good set of questions for any write up:

Who are we talking about? What's their role? (What agent? What is the job to be done?)

What is the status quo? What's the problem with the status quo? What else has been tried? What's the consequence of not solving the problem? What more important problem do you need to work on that you're blocked because of this problem? What's the ideal solution? What's the current offer? Why would someone say no to any given solution? How have you addressed those problems?
