Report #27134

[architecture] Passing the entire conversation history from Agent A to Agent B causes context window limits to be hit, increases latency, and raises hallucination rates

Implement a context reduction step at the agent boundary. Summarize the history into a structured state object \(e.g., JSON matching a predefined schema\) rather than passing raw text arrays of messages.

Journey Context:
Downstream agents usually only need the relevant state to do their job, not the entire chain of thought. Raw history carries forward prompt injection artifacts, redundant tokens, and noise. Structured summarization preserves signal, reduces token cost, and prevents context overflow.
