[frontier] Central orchestrator agent becomes a bottleneck and single point of failure in multi-agent systems

Use agent handoffs instead of orchestrator-worker: each agent can transfer control to another agent by returning a handoff object containing the target agent reference and serialized context. The runtime swaps the active agent and passes context—no central router needed.

Journey Context:
The orchestrator-worker pattern \(one 'manager' agent dispatches to 'worker' agents\) is the default multi-agent architecture. In production, the orchestrator becomes a bottleneck: it must understand all agent capabilities, manage all context, and make all routing decisions. As agents are added, the orchestrator's prompt grows and its reliability drops. The handoff pattern inverts this: each agent declares which agents it can hand off to, and transfers control by returning a handoff instruction. The runtime simply swaps the active agent. Benefits: \(1\) No single prompt needs to know everything, \(2\) Agents can be added without modifying a central orchestrator, \(3\) Context is scoped to the active agent, reducing noise. Tradeoff: less global control—you must design handoff chains carefully to prevent infinite loops \(agent A hands off to B, B hands off to A\). Mitigation: maintain a handoff depth counter and force-terminate after N handoffs. This pattern works best when agent boundaries align with task boundaries \(e.g., a billing agent hands off to a technical support agent, not to a general-purpose agent\).
