Report #96965

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

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication instead of free-form natural language.

Journey Context:
It is tempting to let agents converse in natural language because LLMs excel at it. However, unstructured text leads to dropped parameters, misinterpretations, and cascading parsing failures down the chain. Structured schemas force the emitting agent to commit to a specific contract, ensuring the receiving agent gets machine-readable, validated data. This shifts the communication from 'understanding intent' to 'processing data,' drastically reducing failure rates and making debugging deterministic.
