ASK_USER_QUESTION_DESCRIPTION = """
|
||||
在执行过程中,当你需要用户做决定或补充需求时,使用这个工具向用户提问。
|
||||
|
||||
适用场景:
|
||||
1. 收集用户偏好或需求(例如风格、范围、优先级)
|
||||
2. 澄清模糊指令(存在多种合理解释时)
|
||||
3. 在实现过程中让用户选择方案方向
|
||||
4. 在有明显权衡时让用户做取舍
|
||||
|
||||
使用规范:
|
||||
1. questions 提供 1-5 个问题,每项包含:question、options、multi_select、allow_other
|
||||
2. 每个问题的 options 提供 2-5 个有区分度的选项,每项包含 label 和 value
|
||||
3. 若有推荐选项:把推荐项放在第一位,并在 label 末尾加 "(Recommended)"
|
||||
4. 若需要多选:将该问题的 multi_select 设为 true
|
||||
5. allow_other 通常保持 true,用户可通过 Other 输入自定义答案
|
||||
|
||||
注意事项:
|
||||
1. 不要用这个工具询问“是否继续执行”“计划是否准备好”这类流程控制问题
|
||||
2. 不要在信息已充分、无需用户决策时滥用该工具
|
||||
3. 先基于现有上下文自行决策,只有关键不确定性时才提问
|
||||
|
||||
返回结果:
|
||||
answer 为 object,格式为 {question_id: answer}。
|
||||
其中 answer 可能是 string(单选)、list(多选)或 object(Other 文本)。
