Report #36786

[frontier] Multi-agent orchestration requires a central controller agent that dispatches work to specialist workers

Replace the orchestrator-worker topology with the Handoff pattern: agents directly transfer control and full conversation context to the next agent via a typed handoff object, eliminating the central router entirely.

Journey Context:
The hub-and-spoke orchestrator feels natural — one smart agent decides who does what. In production it breaks down: the orchestrator becomes a bottleneck and single point of failure, context gets lost in translation between orchestrator and worker, and the orchestrator itself hallucinates routing decisions. The Handoff pattern \(demonstrated in OpenAI's Swarm reference implementation\) inverts this: each agent knows which agents it can hand off to and returns a handoff object instead of a final response. The caller simply continues the conversation with the new agent. Full context travels with the handoff. No agent needs global knowledge of all capabilities. Tradeoff: you lose centralized control over routing and observability, so you must add tracing at the handoff boundary. But the reliability and simplicity gains are decisive — the orchestrator was never adding value proportional to its cost.
