Report #68772

[architecture] Agents hallucinating parameters when passing context via natural language

Enforce structured schema \(e.g., JSON Schema, Pydantic\) for all inter-agent message payloads and handoff arguments.

Journey Context:
LLMs are unreliable at extracting unstructured text into actionable parameters. Free-form messaging leads to cascading parsing errors when the receiving agent expects specific variables. Structured schemas force the emitting agent to validate its output against a schema, ensuring the receiving agent gets machine-parseable, deterministic data, trading off conversational flexibility for system reliability.
