Report #75251

[architecture] Context window overflow from passing full conversation history between agents

Use a shared, external state store \(Blackboard pattern\) with summarization. Agents read only the specific state keys they need and write their outputs to the store, passing only references \(or minimal summaries\) during handoffs.

Journey Context:
Naively appending the entire conversation history of Agent A to Agent B's prompt quickly exhausts context limits and degrades performance. A shared state store decouples the data from the conversation, allowing agents to operate within tight context windows while maintaining global awareness.
