Report #71956

[architecture] Agents failing to extract or hallucinating parameters from free-form inter-agent messages

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic\) for all agent-to-agent communication. Reserve natural language only for the human-facing boundary.

Journey Context:
When Agent A passes a free-text summary to Agent B, B often loses specific variables \(like IDs or names\) or hallucinates missing ones. Structured schemas force the emitting agent to output exact, typed fields, allowing the receiving agent to parse them programmatically without relying on LLM extraction, drastically reducing error propagation.
