Report #43819
[frontier] Central orchestrator agent becomes a bottleneck in multi-agent systems — context overflow, single point of failure, latency compounding
Replace orchestrator-worker topology with agent handoff pattern: agents transfer full conversation state and control directly to the next specialist agent via structured handoff functions
Journey Context:
The orchestrator-worker pattern \(one 'brain' agent dispatches to worker agents\) is the first multi-agent pattern everyone reaches for. It fails at scale because: \(1\) the orchestrator's context window fills with summaries of every worker's output, \(2\) every interaction requires two LLM calls \(orchestrator decides \+ worker executes\), \(3\) the orchestrator becomes a single point of failure. The handoff pattern, introduced by OpenAI's Swarm framework, lets each agent directly transfer control to another agent along with the full conversation context. The receiving agent gets first-class context, not a compressed summary. Tradeoffs: handoffs are harder to debug \(no central log of all decisions\), agents can loop indefinitely \(mitigate with max-handoff counters and depth limits\), and each agent must know which other agents exist. But for systems with 3\+ specialist agents, handoffs dramatically reduce latency and improve context fidelity compared to orchestrator-mediated communication.
