Report #52711

[architecture] Passing the entire conversational history between agents, exhausting context windows and increasing hallucination

Use a shared state object or 'scratchpad' where agents read only their required schema inputs and write only their specific structured outputs, rather than passing raw chat logs.

Journey Context:
Naive multi-agent systems just append messages to a list. As the chain grows, the context window fills up, leading to truncated instructions and high token costs. By abstracting state into a shared structured store, agents operate on bounded, relevant data. Tradeoff: Requires strict schema definitions for the state object and loses subtle conversational nuance, but prevents context overflow.
