BlackBeltTechnology/pi-agent-dashboard ? reverse-engineered prompt

Build me a web dashboard for my pi coding agent sessions that I can open in one browser tab and use on my laptop or phone.

I want to see all active sessions at once, jump into any one of them, and watch the agent chat update live as it works. It should also let me follow the terminal output, view file diffs, and see any OpenSpec changes attached to a session. Make it easy to start and control sessions from the dashboard, including parallel runs, and show useful info like session status and token or cost usage if available.

It should work alongside pi’s normal terminal interface, not replace it. I also want a simple setup that can run locally, and a way to access it remotely from my phone with something like a tunnel or local network discovery. Use the current docs online if you need to.
