The useful version of the AI productivity story is still boring: throughput goes up when more independent work can happen at the same time without losing control of the system.
That is why Herdr is interesting.
Not because it is another coding agent. It is not. Herdr is an agent multiplexer. The simplest explanation is "tmux for coding agents", but that only gets halfway there. Like tmux, it keeps real terminal sessions alive. Unlike tmux, it tracks whether agents are working, blocked, done, or idle, and exposes a CLI and socket API that scripts or agents can drive.
That last part matters more than the UI. The bigger gain comes when you can supervise several agents at once, give each one a narrow task, and only spend human attention where the system needs a decision.
the machine where the work happens
