Report #79586

[architecture] Broadcasting the entire conversation history of all agents to every other agent, rapidly exhausting context windows

Use a 'scratchpad' or 'blackboard' architecture where agents only read/write specific structured summaries relevant to their task, rather than raw chat logs.

Journey Context:
Naive multi-agent systems append all messages to a shared list. This is O\(N^2\) context growth and poisons the context window with irrelevant internal monologue from other agents. Blackboard pattern allows O\(N\) targeted reads. Tradeoff: Requires an orchestrator to manage the blackboard schema and decide what gets published, but saves context space and reduces hallucination from noise.
