 ## 工具与文件
 
-工具使用独立的 `managed_browser_*` 前缀：打开、状态、DOM 快照、页面操作、附件上传、下载导出。页面操作支持导航、标签页、点击、填写、键盘、滚动和截图。普通网页先使用 DOM 快照与元素引用，确有视觉需求时再截图。
+工具使用独立的 `managed_browser_*` 前缀：打开、状态、DOM 快照、页面操作、附件上传、下载导出。页面操作支持导航、标签页、点击、填写、拖动、键盘、滚动和截图。普通网页先使用 DOM 快照与元素引用，确有视觉需求时再截图。
+
+Bot 拖动使用 `managed_browser_action` 的 `drag` 动作，传入当前截图坐标 `fromX/fromY/toX/toY`；Runner 执行按下、经过中间位置、到达终点和松开，支持滑块、文字拖选与 HTML 元素拖放。人工接管在移动超过 5 个屏幕像素后开始连续拖动，按住期间更新页面画面；只保留待发送的最新移动位置，最终松手位置独立发送，移出画面时限制在画面边界。拖动沿用控制凭据、代次和近期截图校验；中间阶段保留近期截图，结束后作废。
+
+Esc、窗口失焦、取消触摸或交还控制权会取消拖动并释放鼠标。控制切换、页面跳转和动作失败时 Runner 同样清理按键；前端按住不动时每秒续报位置，超过 5 秒未收到有效更新则自动释放。界面基于请求和截图更新，实际跟随速度受节点往返与截图耗时影响。拖动功能需要同时更新 Web 和执行节点的 Runner。
 
 下载先取得 `downloadId`，通过 `managed_browser_export` 作为现有对话附件交付。上传使用当前账号有权访问的附件 `fileId`，模型不传宿主文件路径。单文件上限 25 MiB。
 
 同一轮已授权 VM 时，额外提供 `managed_browser_to_vm` 与 `managed_browser_upload_vm`。复制使用现有 VM 分块文件协议、摘要校验和路径边界；默认不覆盖文件，也不挂载宿主目录。跨环境文件还受全局文件传输大小设置约束。
 
-网页网络请求走经鉴权的公网代理，拒绝回环、私网与重新解析到私网的目的地址；既有连接也定期检查授权。当前禁用 Service Worker 和 WebSocket，因此依赖这些功能的网站可能不完整。DOM 元素快照目前针对主页面；拖拽等高级输入尚未接入。浏览器不支持通过任意 JavaScript、CDP 或宿主命令接口绕过这些边界。
