Report #13172

[architecture] Passing entire conversation histories between agents, causing context window bloat and excessive token consumption

Pass only structured 'task context' or state deltas between agents. Use a shared scratchpad or state graph that agents read from/write to, rather than forwarding full transcripts.

Journey Context:
Naively appending Agent B's history to Agent A exponentially grows the context, pushing out Agent A's original instructions and hitting token limits. Tradeoff: Summarization/delta-passing loses granular conversational details, but keeps the system operable within context limits and reduces latency.
