Report #81457

[architecture] Passing full conversation histories between agents causes context window overflow and degrades instruction-following in later steps

Implement state summarization or strict message pruning at agent boundaries. Only pass the structured output and a distilled summary of the prior context to the next agent, rather than the raw transcript.

Journey Context:
To maintain coherence, developers often pass the entire history. But in multi-agent loops, this history grows quadratically. The LLM loses track of its system prompt \(attention dilution\) and hits token limits. The fix is to treat inter-agent handoffs like API requests: send only the payload \(structured output\) and necessary metadata \(summary\). Tradeoff: Loss of fine-grained nuance from the original conversation, requiring careful summarization strategies.
