[architecture] Passing full conversation histories or massive outputs between agents exhausts context windows and degrades reasoning

Implement a 'Summarizer' or 'Distiller' agent step before routing large payloads across agent boundaries. Pass only the structured summary and a reference URI to the raw data.

Journey Context:
To maintain context, developers often pass the entire history of Agent A to Agent B. As the chain grows, the context window fills up, leading to truncated inputs, higher costs, and the 'lost in the middle' phenomenon where LLMs ignore early context. Instead, agents should communicate via distilled summaries and pointers \(e.g., S3 URLs or vector DB IDs\). The tradeoff is that some granular detail is lost in summarization, but it preserves the agent's ability to reason effectively within its context limit.
