[frontier] Central orchestrator agent becomes context bottleneck and single point of failure in multi-agent systems
Replace orchestrator-worker topology with agent handoffs: each agent can transfer control directly to another specialized agent by returning a handoff object. Eliminate the central router. Each agent operates with its own full context window and transfers only the necessary state to the next agent.
Journey Context:
The orchestrator-worker pattern where one manager agent calls sub-agents as tools seems natural but has critical failure modes in production: the orchestrator context window fills with sub-agent results, every intermediate output must round-trip through the orchestrator doubling token cost, and the orchestrator becomes a single point of failure. The handoff pattern inverts this: agents directly transfer control to each other. Each agent gets a fresh focused context window. The tradeoff is less global visibility because one agent does not automatically see what another did, but this is actually beneficial because it prevents context pollution where irrelevant details from one subtask confuse another. State is passed explicitly via handoff payloads, not implicitly via shared context. Production systems with three or more agents are finding handoffs dramatically more reliable than orchestration. The key implementation detail: handoff objects must include both the transferred data and a clear description of what the receiving agent should do with it.
