Report #88181

[architecture] Agents hallucinate parameters when passing context via free-form natural language

Enforce structured-schema messaging \(e.g., JSON Schema validated outputs\) for all inter-agent handoffs, restricting natural language to user-facing interactions only.

Journey Context:
Developers often treat inter-agent communication like human chat, assuming the receiving LLM will 'figure it out.' This leads to dropped variables, misinterpreted intents, and cascading errors. While natural language is flexible, it is non-deterministic. Structured schemas force the emitting agent to serialize exactly what the receiving agent's function signature expects, trading conversational fluency for machine-level reliability and deterministic parsing.
