Report #104113

[synthesis] Downstream agent trusts malformed output from an upstream agent

Define a machine-verifiable handoff schema and require the receiver to validate and reject; never pass free-form natural-language state between agents.

Journey Context:
Multi-agent frameworks like AutoGen pass natural-language summaries between agents, which resembles distributed systems without message integrity checks. A small hallucination or truncation in one agent's summary becomes the next agent's ground truth. JSON Schema validation plus explicit rejection semantics, borrowed from RPC design, is the only reliable boundary.
