[synthesis] Multi-agent handoffs drop critical null or edge-case values through summarization

Never pass state between agents using natural language summaries. Use a strictly typed, immutable JSON schema \(a 'handoff contract'\) for all inter-agent communication, explicitly defining fields that can be null, and enforce schema validation at the receiving agent's entry point.

Journey Context:
In frameworks like AutoGen or CrewAI, Agent A often passes a summary string to Agent B. If Agent A encounters a missing value, it might summarize 'processed user data' and omit the missing field. Agent B assumes the field exists and constructs a payload, causing a downstream null pointer exception or database constraint violation. Natural language is a lossy compression algorithm for state; structured contracts prevent the telephone game effect.
