If tmux can know what an agent is, it can be leveraged to communicate with an instance of that agent (input and output) given it owns the PTY, and that terminal output can be structured somehow.

If it can communicate with the agent, it can be used to drive the agent - to send it tasks, and communicate the status of those tasks.

And so Herdr - and Superlogical, and others, is a tool which leverages PTY ownership and terminal protocols to allow orchestration of coding agents across vendors using their CLI surfaces.
