[architecture] Multi-agent chain degrades in quality due to context window pollution from intermediate artifacts

Implement context pruning or summarization at agent handoffs. Do not blindly pass the entire conversational history; pass only the minimal required state and the schema-validated output.

Journey Context:
To maintain state, developers pass the full chat history from Agent A to Agent B. As the chain grows, the context window fills with irrelevant intermediate steps, increasing latency, cost, and the probability of the agent latching onto stray context. The tradeoff is between full history \(maximum information, high noise\) and minimal state \(low noise, potential loss of nuance\). Minimal state with strict schema contracts is the right call for robust pipelines.
