Report #64578

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

Enforce strict JSON schema contracts \(e.g., Pydantic/Zod\) at the agent boundary; fail fast and reject the output if validation drops.

Journey Context:
LLMs default to unstructured text. Passing raw text directly causes the receiving agent to hallucinate structure or fail when extracting variables. Structured output \(JSON mode\) combined with schema validation acts as a compiler for the multi-agent pipeline. Tradeoff: strict schemas restrict LLM flexibility and may increase refactoring overhead, but in pipelines, reliability and deterministic handoffs always outweigh flexibility.
