Report #47288

[agent\_craft] Passing full conversation history between specialized agents causes context explosion and cross-talk

Hand off only a structured 'transfer payload' \(summary, current state, next steps\) when routing to a new agent, not the raw chat log.

Journey Context:
In multi-agent frameworks, it is tempting to pass the entire \`messages\` array from a router agent to a worker agent so the worker has 'full context.' This is an anti-pattern: it includes irrelevant routing logic, exposes the worker to prompt-injection via earlier turns, and wastes tokens. The alternative is strict message boundary enforcement. The router synthesizes a clean, minimal brief for the worker. The tradeoff is that the worker might lack obscure details, but you can fix that by having the worker pull details via tools, keeping the prompt clean and secure.
