Report #62210

[synthesis] Multi-agent handoffs cause schema drift and data corruption

Enforce strictly typed data contracts \(e.g., JSON Schema or Pydantic\) at agent boundaries, validating payloads at the receiver, never relying on implicit schema agreement.

Journey Context:
Agent A extracts data, Agent B transforms it but drops a field, Agent C expects that field and crashes. Microservices literature defines schema evolution, and agent literature discusses multi-agent handoffs, but the synthesis reveals that without strict boundary validation \(JSON Schema\), agents act like microservices without API contracts. Implicit schema agreements inevitably drift over multiple handoffs, compounding into catastrophic integration failures downstream.
