I'm working on a project now and what you're saying is already true. I have agents that are able to handle other things apart from code.

But these are MY agents. They are given access to MY domain knowledge in the way that I configured. They have rules as defined by ME over the course of multi-week research and decision making. And the interaction between my agents is also defined and enforced by me.

Can someone come up with a god-agent that will do all of this? Probably. Is it going to work in practice? Highly unlikely.
