Report #39439

[architecture] Passing the entire conversation history between agents, blowing up token limits and confusing the receiving agent with irrelevant tool outputs and dead-end reasoning

Implement a summarization and schema-extraction handoff pattern. Only pass structured state deltas and a concise summary of the previous agent's actions

Journey Context:
Naive multi-agent setups just append messages. This includes irrelevant tool outputs \(like full file reads\) and dead-end reasoning. The receiving agent gets confused by the noise. Extracting only the relevant state \(e.g., file X modified, function Y added\) keeps the context clean and token costs predictable.
