Every agent.
One canvas.

Each running agent is a node, the ones in the app and the ones in your other terminals. Working ones pulse fast, idle ones breathe, forks hang off their parent. Drag from one node to another and context starts flowing. ⌃Tab flips the app into it, ⌘-click a node opens its session.

Context flows
where you point.

No orchestrator, no broadcast. You decide who reads whom, and the rest happens on its own: context arrives with the next prompt, messages land in the inbox.
