📄 中文摘要
传递给大型语言模型（LLM）的 JSON Schema 不仅仅是一个结构性契约，它还是一个直接控制输出质量的提示。字段名称、描述、顺序和枚举值都能像系统提示一样引导模型的行为。设计得当可以获得可靠的优质输出，而设计不当则可能导致“结构有效的垃圾”。AWS Bedrock 最近推出了受限解码，确保响应符合 JSON Schema，但结构保证并不意味着质量保证。设计合适的 Schema 是确保高质量输出的关键。

Your JSON Schema Is a Prompt - Tips for AWS Bedrock Structured Output
The JSON schema provided to a large language model (LLM) serves not only as a structural contract but also as a prompt that directly influences the quality of the output. Field names, descriptions, ordering, and enum values guide the model's behavior similarly to a system prompt. Properly designed schemas yield reliable, high-quality outputs, while poorly designed ones can result in 'structurally valid garbage.' AWS Bedrock has recently introduced constrained decoding, which ensures responses adhere to a JSON schema; however, guaranteed structure does not equate to guaranteed quality. Designing effective schemas is crucial for achieving high-quality outputs.
