Supervise Workers

Agent Hub treats every routed instruction as a work item. A session normally has one active item and zero or more queued items.

Normal Flow

1. Resolve the target project and worker.
2. Create a durable work item.
3. Dispatch the message.
4. Wait for the worker to ACK the exact delivery.
5. Monitor structured progress.
6. Queue follow-up instructions behind active work.
7. Advance the next queued item when the active item is accepted, done, cancelled, or safely resolved.

Follow-Up Messages

If a worker is busy, a new instruction for the same worker should queue. It should not be typed into a busy composer or blended into the current summary.

Restart Recovery

When a worker must restart, Hub carries:

• active work item
• queued items
• pending delivery records
• recent worker output
• git and worktree context
• review and deploy records

The fresh worker continues from the durable continuation packet instead of relying on chat memory.

Watcher

The watcher polls background sessions, advances safe queues, requests missing handoffs, escalates stalled handoff requests, and notifies when a session needs review, needs a decision, or completes a durable run.
