[synthesis] Multi-agent handoffs cause data drift through implicit schema assumptions

Enforce strict, machine-readable schemas \(like Pydantic models or JSON Schema\) at agent handoff points, and programmatically validate the payload before the receiving agent starts execution.

Journey Context:
When Agent A passes data to Agent B, it often formats it as unstructured or loosely structured text. Agent B interprets this text based on its own weights, leading to subtle misinterpretations \(e.g., treating a list of IDs as a single string\). By step C, the data is completely corrupted. This is the LLM equivalent of the microservice anti-pattern of implicit contracts. The synthesis of distributed systems schema registries and multi-agent orchestration reveals that without programmatic validation, LLMs will confidently hallucinate the shape of the data.
