[architecture] Intermediate agent outputs bloat the context window, pushing out critical initial instructions and causing goal drift

Summarize or compress intermediate agent outputs before passing them to the next agent in the chain, preserving only the schema-contracted payload.

Journey Context:
In a long chain of agents \(A -> B -> C -> D\), passing the entire conversational history or raw tool outputs from A to D quickly exhausts the context window. When the context window fills, models suffer from the 'lost in the middle' phenomenon and forget the original system prompt, leading to goal drift. The fix is to strictly curate the context: Agent B should only pass the structured JSON result to Agent C, not the verbose reasoning trace, or use a summarization step. The tradeoff is loss of fine-grained reasoning context for debugging, but it maintains the operational integrity of the downstream agent's instructions.
