[frontier] Building multi-agent systems with a central orchestrator that routes all messages through a single controller agent, creating a context bottleneck

Implement the handoff pattern: give each agent the ability to transfer full conversation control directly to another specialized agent, passing along the conversation history and a context message, rather than routing through a central orchestrator

Journey Context:
The orchestrator-worker pattern \(one boss agent dispatching to workers\) feels natural but creates critical bottlenecks in production: the orchestrator must understand all agent capabilities \(growing prompt size\), all context must flow through it \(context window pressure\), and it becomes a single point of failure. The handoff pattern, demonstrated in OpenAI's Swarm framework, eliminates the middleman: any agent can transfer control to any other agent. The receiving agent gets the full conversation plus a handoff message explaining why. Benefits: no orchestrator bottleneck, linear context growth \(not multiplicative\), and agents only need to know about their immediate handoff targets. Tradeoffs: harder to enforce global policies \(need middleware or guardrails\), and without clear termination conditions, agents can hand off in circles. Mitigation: add a handoff depth counter and explicit termination agents.
