Report #63682

[frontier] Hub-and-spoke multi-agent architectures create single point of failure and context window bottlenecks at the supervisor level

Implement decentralized handoff patterns using LangGraph Swarm where agents dynamically transfer control via handoff functions and shared thread state without central coordinator

Journey Context:
Traditional supervisor patterns fail at >5 agents due to context window limitations in the coordinator node, which must maintain awareness of all agent outputs. The Swarm pattern eliminates the supervisor by allowing agents to explicitly hand off to other agents via function calls that transfer the active state. This uses a shared thread state object that persists across handoffs, enabling long-running workflows without centralized context accumulation. Tradeoff: requires careful state isolation design to prevent cross-agent pollution.
