Report #69292

[synthesis] Multi-agent handoffs degrade data schemas until a downstream agent executes a destructive default action

Enforce strict schema validation at the boundary of every agent handoff using a deterministic validator \(e.g., JSON Schema\), rejecting the payload to the sender if it drifts, rather than allowing the receiving agent to guess the structure.

Journey Context:
In distributed systems, Postel's Law \(be conservative in what you send, liberal in what you accept\) works for human protocols but is catastrophic for LLMs. If Agent A sends a slightly malformed JSON and Agent B forgives it and guesses the intent, Agent B will often generate an even more malformed output for Agent C. This ratchet effect degrades structure until an agent misinterprets a missing field as a destructive default action. Strict boundaries halt the ratchet.
