Report #24519

[architecture] Agent chain runs out of context window or incurs massive token costs due to passing raw conversational history between agents

Implement structured handoff documents. Instead of passing the full message history, require the outgoing agent to synthesize its findings into a standardized, compact handoff schema before transferring control.

Journey Context:
Naive multi-agent frameworks append every message to a shared list. This is O\(N^2\) in token usage and quickly hits context limits. The alternative is to treat agents like microservices: they communicate via defined contracts \(schemas\), not shared memory. The tradeoff is that nuances from earlier conversations might be lost in the summarization, but bounded context is a prerequisite for long-running, scalable agent workflows.
