[architecture] Context window overflow and cost explosion from synchronizing full conversation histories between agents

Pass only structured state deltas or summaries between agents, rather than appending the entire raw chat history.

Journey Context:
Naive setups inject Agent A's full history into Agent B's prompt to maintain context. This quickly hits token limits, increases latency, and dilutes the signal with noise. Passing a structured TaskResult schema \(what was done, what failed, what is next\) keeps the context lean. The tradeoff is the loss of subtle conversational nuance, but agents rarely need nuance to execute a function.
