Report #44423

[architecture] Unstructured text handoffs between agents cause cascading parsing failures and hallucinated state

Enforce strict JSON Schema contracts \(e.g., via Pydantic or Zod\) at agent boundaries, treating inter-agent communication like microservice API contracts. Reject and retry if validation fails.

Journey Context:
Developers often let agents 'talk' in natural language for flexibility, but LLMs easily omit required fields or hallucinate formats. Structured output forces determinism where it matters. The tradeoff is slightly higher token cost and latency for schema enforcement, but it prevents silent data corruption down the chain.
