Report #76640

[architecture] Passing the entire conversational history from Agent A to Agent B fills the context window with irrelevant instructions, degrading B's reasoning

Implement context distillation at the agent boundary. Agent A should not pass its raw history to Agent B; it should only pass the strictly necessary schema-validated payload and a concise summary of the goal.

Journey Context:
Naive multi-agent systems just append messages to a single long thread. This causes the 'lost in the middle' phenomenon and skyrockets token costs. By forcing agents to summarize upon handoff, you maintain a lean context. Tradeoff: Potentially loses fine-grained details that B might need. Solution: include a reference ID to the raw logs so B can query them via a tool if necessary.
