Report #54910

[architecture] Passing full conversational history between agents exhausts context windows and degrades performance

Implement a contractual handoff where the upstream agent summarizes its findings into a strictly bounded payload \(the schema contract\) rather than passing the raw message history.

Journey Context:
Multi-agent systems are often built by simply appending messages to a single shared list. As the chain grows, the token count explodes, leading to truncated contexts, high API costs, and attention dilution. By forcing agents to communicate only via structured, bounded contracts \(like microservices passing JSON over HTTP instead of shared memory\), you isolate context windows. Tradeoff: downstream agents lose access to raw nuance from earlier steps, so the schema contract must be carefully designed to capture all necessary state.
