Report #59669

[architecture] Shared memory architecture causes context window poisoning where one agent's verbose output degrades subsequent agents

Implement a state-scrubbing step or a dedicated manager agent that distills, summarizes, and strictly formats shared state before passing it to the next agent, rather than appending raw outputs to a shared context.

Journey Context:
Developers often dump the entire history of Agent A into Agent B's prompt to maintain context. This hits token limits and introduces noise \(the 'lost in the middle' phenomenon\), degrading B's reasoning. Tradeoff: an extra summarization step adds latency and risks losing nuance, but ensures the receiving agent operates only on high-signal, relevant data instead of drowning in raw logs.
