Really nice approach. Running parallel agents is the obvious next step after single-agent works, but the coordination + cost tracking becomes the blocker.

One thing I'd add: make cost-per-agent visibility mandatory from day one. When you've got 5-10 agents running, token burn compounds fast. Each agent needs its own cost dashboard.

We bake this into every agent setup now—cost awareness prevents expensive mistakes.

One thing we’ve been thinking about with Amux is that the unit of compute shouldn’t just be the terminal session—it should be the agent itself. That means each pane/session can expose things like:

* tokens in / tokens out * cumulative run cost * model + pricing tier * runtime duration * optional budget caps

So when you spin up 5–10 agents, you can immediately see which one is burning tokens or looping.

Longer term I’d love for Amux to treat agents a bit like processes in `htop` where you can see resource usage across all agents in one place and kill/restart the expensive ones quickly.

Curious how you're currently surfacing cost in your setups — logs, dashboards, or something inline with the agent runtime?
