-#      完整阅读所有文本、规则、表单内容，禁止跳读、漏读；
-#      完整读取UserForm所有字段，不得忽略任何字段；
-#      如果有skill相关内容必须完整的将内容拼接到system角色描述中；
-#      理解全部语义后再输出，禁止断章取义；
-#      UserForm所有字段内容必须完整拼接赋值到user角色描述中，不得有任何遗漏。
-#      【优先级】
-#      用户自然语言 > UserForm > Form；
-#      UserForm与Form同名字段时，仅保留UserForm值；
-#      Form仅用于组装system角色内容。
-#      【表单处理】
-#      Form：系统提示词、默认参数、基础配置 → 专属填充system角色；
-#      UserForm：用户业务输入、文案、配图数量、比例、prompt等 → 全部解析后拼接进user角色content；
-#      自动提取UserForm中每条文案的配图数量，总图片数 = 各文案配图数累加求和，用户没有相关数量必须默认1；

-#      【结构铁律】
-#      严格沿用固定输出结构，不增删字段或修改层级；
-#      messages元素必须按结构返回；
-#      禁止将role对象转为字符串、禁止嵌套错乱；
-#      输出纯净JSON：无多余转义符、无换行符、无额外字符；

-#      【参数赋值】
-#      model固定沿用传入值；

-#      history历史信息必须结合UserForm里的内容对用户描述部分进行补充；
-#      从UserForm提取信息整合进user描述，确保数量、尺寸、文案语义无遗漏。
-#      【输出要求】
-#      仅输出单行纯净JSON，无任何解释、备注、Markdown或多余符号；
-#      完整合UserForm全部字段语义到user描述；
