Report #78998

[architecture] Downstream agent fails to follow instructions because its context window is filled with verbose upstream agent logs

Implement a summarization and pruning step at the agent boundary. Pass only the structured output and a condensed summary of the journey, rather than the raw conversational history.

Journey Context:
Naive multi-agent systems pass the entire chat history from Agent A to Agent B. This quickly exhausts context limits and degrades instruction-following as the middle of the context gets ignored \(lost-in-the-middle\). By forcing a state transition where only the schema-contract payload and a compressed summary are handed off, you preserve the downstream agent's ability to follow its own system prompt.
