Report #48917

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

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication. Reserve natural language strictly for user-facing outputs or bounded reasoning scratchpads.

Journey Context:
Because LLMs natively output natural language, it is tempting to pipe Agent A's raw text into Agent B's prompt. This creates a brittle, non-deterministic API. Agent B might miss a crucial status flag, hallucinate a parameter, or fail to extract the actual payload. Structured schemas force the generating agent to serialize its output into a deterministic format, allowing the receiving agent to parse it reliably without relying on LLM inference for routing or state extraction.
