Report #81781

[architecture] Agents failing to parse each other's outputs or hallucinating function arguments during handoffs

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication and handoffs. Ban free-form natural language for task payloads.

Journey Context:
It is tempting to let agents 'chat' via natural language because LLMs excel at generating it. However, free-form chat leads to semantic drift, missing parameters, and parsing failures down the line. Structured schemas force the sending agent to output machine-readable data and force the receiving agent to ingest exactly what it needs, acting as a rigid contract. This mimics microservices API contracts \(REST/gRPC\) over human language.
