[architecture] Agents communicating via unstructured natural language leading to cascading hallucinations and parsing failures

Enforce structured-schema messaging \(JSON Schema, Protocol Buffers\) for all inter-agent communication, reserving natural language only for the final user-facing output.

Journey Context:
Because agents are LLMs, developers assume they should talk to each other in plain English. This is an anti-pattern. Unstructured outputs from Agent A become noisy inputs for Agent B, compounding hallucination rates and breaking automated parsing. By forcing inter-agent handoffs to conform to a strict schema \(like function calling\), you eliminate ambiguity, reduce token variance, and make the system debuggable and deterministic at the integration boundaries.
