[idea] Optional browser dashboard for checking on agents away from the terminal

[hairbui76]

idea / problem

When I start an agent and walk away from the machine, I have no way to see that it stopped and is waiting on me. It sits blocked until I get back to a terminal, so a two-second answer can cost an hour of wall-clock time.

SSH and reattaching works, and I do it, but on a phone it is awkward enough that I mostly do not bother. The bigger gap is that it is pull-only: I have to think to go and look. Nothing tells me an agent needs attention.

What I actually want is small - see which agents are running and what state they are in, and answer one that is blocked, from whatever device is in my hand.

requested change

An optional, opt-in way to reach a session from a browser on another device:

• see workspaces, tabs, panes and agent status live
• open a pane's terminal and type into it
• be notified when an agent becomes blocked or finishes

Opt-in is the important part. It should be off unless you turn it on, loopback only by default, and absent entirely from builds that do not ask for it - no new dependencies, no extra toolchain, no behaviour change for anyone who never enables it.

I do not assume this belongs in Herdr. It is a large surface to own and the security posture is permanently load-bearing, since typing into a pane over HTTP is code execution as the user running the daemon. "Out of scope" is a complete answer and I would rather hear it than guess.

If there is interest, I have a working prototype on a fork and would be glad to walk through the design, split it up, or hand over the parts that are useful. I am not asking for a pull request to be accepted.

why you want this

I run long agent tasks and step away - other work, commute, end of day. Today the cost of stepping away is that a task can be stalled for an hour on a question I could have answered in seconds.

Being able to unblock an agent from a phone turns that hour back into seconds. Being told it is blocked means I do not have to keep checking, which is the part that actually changes how I work.

Btw it is like remote control but for herdr ^^

For the middle bullet, opening a pane's terminal and typing into it from a browser on another device. shell herdr starts herdr in a shared PTY and prints a link, open it in the phone browser and you are typing into that same session, nothing to install on the phone, no SSH app. shell --read-only herdr for a watch-only link. It does not give you the status overview or the blocked notifications, those still need herdr itself. Disclosure, I work on Pilot Protocol, which develops shell.online. MIT, macOS/Linux.
