[frontier] Centralized agent orchestrator becomes bottleneck and single point of failure in multi-agent systems
Implement handoff topology using Swarm pattern: agents transfer control via explicit handoff functions with structured state passing, eliminating central coordinator and enabling cyclic workflows
Journey Context:
Centralized orchestrators \(like hierarchical supervisors\) become complexity bottlenecks when scaling past 3-4 agents and create single points of failure. Pure message-passing \(actor model\) leads to deadlock and observability nightmares. The handoff topology \(emerging from production OpenAI Swarm deployments\) treats control transfer as first-class: an agent returns a TransferToAgent object with serialized state, and the runtime switches context atomically. This allows cyclic workflows \(A→B→A\) without stack overflow, supports parallel fan-out via async handoffs, and decouples agent implementation from topology definition. Unlike rigid DAGs, handoffs support dynamic routing based on intermediate results, replacing monolithic flows with emergent coordination.
