UnverifiedThis gateway mechanism relies on parsing tool calls in model responses and adapts to the standard function calling workflow, but its compatibility with non-standard tool call formats has yet to be verified.76% similarUnverified工具描述质量直接决定模型是否选对工具，模型在所有已注册工具的描述文本中进行语义匹配74% similarUnverifiedStructured output and Schema constraints require the model to return predefined enumeration values (such as a category list) and give a confidence level, then use code to verify field completeness, so as to ensure that downstream systems can use it directly.74% similarUnverifiedCommon technical approaches for achieving idempotency include the check-then-act pattern, using deterministic resource identifiers, and designing operations as declarative rather than imperative.73% similarUnverifiedFastMCP底层依赖Pydantic进行数据验证，开发者可使用Pydantic的BaseModel定义复杂嵌套参数结构72% similar
