問題文
A tool returns a JSON object in structuredContent. Which statement about that field is correct?
選択肢
- If the tool declares an outputSchema, the server must return structured results that conform to it, and the client should validate the result against it.
- It is schema-constrained generation, and declaring an outputSchema causes the model to emit matching output.
- A tool that returns structuredContent must omit the content field.
- structuredContent may only be a JSON object, never an array or a scalar.
