Report #59227

[frontier] Multi-agent system uses a persistent orchestrator agent that routes all messages, creating a context bottleneck and single point of failure

Replace the persistent orchestrator with ephemeral agent handoffs: each agent runs only for the duration of its task, transfers full context to the next agent via a structured handoff, and terminates. Implement handoffs as function calls where Agent A invokes Agent B as a tool, passing serialized conversation and task context as arguments.

Journey Context:
The orchestrator pattern—one 'boss' agent dispatching to workers—is the first thing everyone builds and the first thing that fails in production. The orchestrator's context window becomes a bottleneck as it accumulates all sub-agent outputs. Every message passes through it, adding latency and token cost. The orchestrator becomes a single point of failure for routing decisions. The handoff pattern, demonstrated in OpenAI's Swarm framework, eliminates the orchestrator entirely. Agent A handles the user until it determines Agent B should take over; it calls Agent B as a tool, passing the conversation and task-specific context. Agent B runs and either completes the task or hands off to Agent C. No agent persists longer than needed. The key insight: handoffs work because modern LLMs are good at deciding WHEN to transfer, and structured outputs make the transfer reliable. The tradeoff: you lose global visibility—no single agent sees the full picture. Mitigate by including a concise running summary in every handoff payload. This pattern wins because it's simpler, cheaper, and scales linearly with agent count rather than quadratically with orchestrator context growth.
