Report #17133
[research] Multi-agent handoffs lose critical context, causing downstream agents to hallucinate
Inject a structured 'handoff manifest' \(JSON containing current state, achieved goals, and explicit next intent\) into the receiving agent's system prompt, rather than relying on the conversational history to implicitly carry state.
Journey Context:
Passing raw chat history between agents hits context window limits and introduces noise. The receiving agent struggles to differentiate resolved context from current directives. Explicit state serialization \(the handoff manifest\) forces the orchestrator to distill only the necessary context, acting as an information bottleneck that prevents context window poisoning and silent degradation in the downstream agent.
