[frontier] Agent quality degrades over long conversations — context rot causing contradictions and hallucinations

Spawn ephemeral agent instances per atomic task. Pass only essential context via structured handoff payloads \(JSON schemas\), not full conversation history. The orchestrator maintains state; workers are stateless and disposable.

Journey Context:
Production agent deployments show that after 20-30 tool calls or conversation turns, agents start to contradict earlier decisions, forget constraints, or hallucinate tool results. The common wrong fix is to increase context window size, which delays but doesn't prevent rot and increases cost/latency. The emerging pattern treats agents like serverless functions: short-lived, single-purpose, with context injected at spawn time. OpenAI's Swarm framework codifies this with handoff primitives that transfer only the conversation and context variables needed. The tradeoff is more orchestration complexity, but the payoff is consistent agent quality and predictable token costs. The orchestrator becomes a state manager; agents become pure reasoners.
