Each Agent runs on a specific machine. When creating a task, choose that machine from the device list.
How a machine gets on the list
Install ChamOS on that machine and sign in with the same account, and it shows up in the list by itself. It connects and runs Agents — no public IP needed, and nothing for you to configure.
Once installed, any client can direct any online machine.
Device status and folders
Each machine in the list shows its own current online status. A remote machine's projects come from directories on that machine — this device's directories are never listed under it as though they were available there.
Choose a runtime from your phone
On your phone, the list shows devices that can run Agents, including phones with a supported runtime. Online ones come first; offline ones stay visible but can't be selected.
On the phone you can open sessions on online machines, see the same timeline, reply, approve, answer questions, and create new Agents — pick an online machine, a directory, and write one sentence.
