You are designing a Claude application that requires structured JSON output for downstream processing. The output schema is clearly defined, and downstream systems will reject malformed JSON. Your application design would ...
A avoid structured output and use free-form text everywhere instead, on the grounds that free-form text is more flexible and handles edge cases better than structured schemas. B structure the prompt to request output in a schema that is described in plain English, with downstream systems parsing whatever shape Claude produces. C define a clear schema and structure the prompt to request output in that schema, with downstream systems handling any validation needed. D define a clear schema, structure the prompt to request output in that schema, and validate Claude’s output against the schema before passing it downstream. Show Answer Answer Explanation A defined schema gives the model an unambiguous target format, while validating the returned JSON against that schema prevents malformed JSON, missing required fields, incorrect data types, and other schema violations from reaching systems that reject invalid input. Anthropic’s structured-output guidance likewise identifies schema-conforming JSON as the appropriate mechanism for reliable downstream processing.
