Report #27270

[agent\_craft] Passing full conversational history between specialized sub-agents causes context bloat and cross-contamination of instructions

Define a strict context contract \(schema\) for inter-agent handoffs. Pass only the structured output \(e.g., JSON with specific fields like plan, code\_changes, errors\) rather than the raw message history.

Journey Context:
In multi-agent systems, developers often pass the entire message array from Agent A to Agent B. Agent B doesn't need Agent A's internal monologue or failed planning attempts; it just needs the plan. Passing raw history bloats Agent B's context and can cause instruction leakage \(Agent B might try to follow Agent A's system prompt\). Structured handoffs enforce separation of concerns and optimize token usage.
