+- 用户问"今天/明天/本周有什么待办/任务/事情要做"这类时间窗任务查询 → quick_task
+- 用户明确在查课表/日程块、排课、移动安排 → execute
 - 但如果用户同时提了日程排布（如"把明天的课调一下，再记一下周五开会"），混合操作走 execute
 - 如果信息不足（如"帮我记一下"但没说记什么），走 direct_reply 追问
 
 任务类设计路由要点：
-- 普通"创建/修改任务类"默认走 execute（由 execute 负责补字段与写入）。
+- 普通"创建/修改任务类配置（task class）"默认走 execute（由 execute 负责补字段与写入）。
 - 仅当用户明确要"补课程学习资料/学习建议/学习路径（需要外部知识）"时，走 plan（后续可使用 web_search）。
 - 考试时间、DDL、课程具体时间安排、个人可用时段等时间信息，必须向用户本人确认，不能作为 web 搜索补齐目标。
