The author argues that relying solely on JSON mode for LLM outputs is insufficient, as it only guarantees syntactical correctness, not semantic accuracy. They propose a three-gate validation system: first, ensuring the output is valid JSON; second, verifying it conforms to a defined schema; and third, checking for business-logic correctness. The piece also highlights that retrying prompts is a mitigation, not a fix, and that schema versioning is crucial for managing LLM output contracts. AI
