Report #30888

[architecture] Multi-agent chain degrades or loses early instructions due to context window overflow from passing full conversational history

Implement state summarization or strict schema-based state handoffs. Instead of passing the entire chat history, pass only the structured output and a distilled summary of the prior state to the next agent.

Journey Context:
Naive multi-agent implementations just append messages to a list. As the chain grows, the context window fills, leading to truncated system prompts, forgotten instructions, and higher cost/latency. By enforcing a contract where agents only pass a strictly defined state object \(schema\) and a compressed summary, you preserve the critical instructions and maintain the agent's focus, trading granular history for reliable execution.
