Report #68868

[architecture] Unstructured text passing between agents causes cascading parsing failures

Enforce strict JSON Schema contracts at agent boundaries using structured output generation and validate payloads with a deterministic validator \(e.g., Pydantic\) before routing to the next agent.

Journey Context:
Agents passing free-text assume the next agent can infer meaning, but this breaks when the downstream agent expects specific keys or types. Structured output forces the LLM to output valid JSON, but LLMs can still hallucinate outside the schema or omit required fields. Deterministic validation acts as a hard trust boundary, catching schema violations before they corrupt downstream state.
