Report #17498

[architecture] Passing entire conversation histories between agents, causing token bloat and cross-contamination of system prompts

Pass only the minimal required state \(delta\) via structured schemas, rather than raw chat logs. Summarize history before handoff.

Journey Context:
Naive multi-agent setups append all messages to a shared thread. This leaks system prompts between agents \(e.g., Agent A sees Agent B's proprietary instructions\) and blows up token limits. State should be explicitly projected and passed as a clean, minimal payload. You must curate what the next agent needs to know, not just dump the transcript.
