[frontier] Multi-agent orchestration is unreliable with persistent long-lived agents that maintain independent state

Use ephemeral agent routines that spawn, execute a discrete task, and hand off to the next agent. Agents should be stateless functions returning \(next\_agent, updated\_context\), not persistent objects with their own state machines. The orchestrator owns all state.

Journey Context:
The naive approach creates multiple long-lived agents with independent state communicating via message passing. This leads to state synchronization hell, race conditions, and unpredictable emergent behavior. The emerging pattern—pioneered by OpenAI Swarm—treats agents as lightweight, stateless routines: each agent is just instructions \+ tools. When done, it hands off by returning the next agent reference with updated context. This eliminates shared state, makes behavior deterministic and testable, and keeps a single source of truth. Tradeoff: agents cannot truly parallelize or maintain independent long-term memory without external stores. But for most production workflows, sequential handoff with shared context is far more reliable than distributed agent networks. Parallelism should be achieved at the tool-call level, not the agent level.
