+授权只覆盖任务创建的标签和用户明确批准借用的标签；标签组仅提供视觉标识，不作为权限依据。即使用户把其他标签拖入组内，模型也不会获得其控制权。结束任务只清理任务创建的标签，不关闭共用窗口及其他对话的标签。上游的本机 daemon 连接模式仍使用原有独立窗口。 + +## 预览与命令 + +自动化命令按对话串行执行。UI 预览通过扩展现有 WSS 的独立请求获取，不进入 daemon

的低帧率截图同步，不是视频流；失败超过 5 秒会提示画面暂未更新。 + +后台任务标签在调试连接期间启用 CDP `Emulation.setFocusEmulationEnabled`，让页面的可见性/焦点与绘制回调继续工作，不激活 Chrome 标签或窗口。仅任务新建或明确借用的标签启用此行为，释放调试连接时由 Chrome 恢复。否则依赖 `requestAnimationFrame`

Chrome 实际返回或调试连接释放；期间预览不再发送重复截图。框架自动附加配置按调试会话复用，断开后重建，失败后可重试。 + +上述上限针对单条 CDP 命令，并非整个 `observe`。复杂页面还要在扩展中进行语义树转换和文本渲染；重复操作按钮的上下文收集复用已扫描的兄弟节点前缀，避免逐按钮重复扫描整个列表。缓存仅存在于本次渲染，按作用域、目标名称和已有上下文隔离，每个父节点最多保留 64 种缓存项。慢观察会以 `[bsk observe] slow observation completed` 输出总耗时和分阶段耗时（不含页面内容）；CDP 超过 2 秒时的提示是等待中告警，`slow command settled` 记录 Chrome 实际返回的耗时，`outcome` 区分返回和失败，`late: true` 表示扩展已经超时但 Chrome 此时才完成；本地超时单独记录为 `command failed`。 + +本轮 Agent 执行结束时，通过工具清理钩子释放当前任务的 Chrome 调试连接。成功完成的普通查询默认关闭任务创建的页面并归还借用标签，避免每轮留下任务分组；输入框的本机浏览器选择偏好仍保留。调用时可设置顶层 `keep_open: true`，为用户要求保留的页面、交付结果或未完成的人工步骤保留整项任务；该标记仅对本轮有效。`request_help` 自动保留任务，人工步骤完成后可通过后续调用的 `keep_open: false` 恢复自动回收。报错、取消、暂停的任务保留现场，不自动关闭。扩展先阻止新截图，再等待在途截图和操作完成，最后释放连接；结束任务也使用同一截图屏障。空闲时服务端只返回缓存画面，卡片显示「已保留最后画面」，不重复截图，下一次浏览器调用恢复连接。Chrome 提示条的消失可能晚于连接释放；同一扩展有其他活动任务时，提示仍可能保留。 + +导航默认等待 `domcontentloaded`，避免已经可读的页面被慢图片等资源拖住；需要完整加载或网络空闲时可显式指定 `wait_until: "load"` 或 `"networkidle"`。文档就绪不代表异步应用内容已加载，操作前仍需观察目标内容是否出现。 + +模型调用采用扁平参数，例如 `{"method":"navigate","url":"https://example.com"}`、`{"method":"click","ref":"e3"}`、`{"method":"observe"}`。Schema 不再提供 `params` 字段，旧的嵌套格式直接拒绝。服务端校验所选动作的必填字段、字段类型及定位条件，再将参数转换为 BrowserSkill 原生 RPC

标签组，开始时会打开到前台，后续创建、选择任务标签只在该窗口内切换；请手动与聊天窗口并排放置。完全遮挡或最小化仍可能导致读取变慢，因此此模式不是不可见后台运行的性能保证。结束任务只清理明确归属于任务的标签，用户后来移入窗口的页面会保留。 + +Agent 模式的输入框提供“本机浏览器”开关，可与联网搜索同时开启。选中后，请求携带 `local_browser_enabled: true`；本轮提示词明确要求使用 `local_browser` 完成适用的网页查询与操作，而不是把设备已配对当作使用意图。知识库、MCP、Skill、Shell 等工具仍按智能体配置和本轮选择正常提供，可以配合检索、处理内容及生成文件。联网搜索与浏览器同时开启时，可以先搜索发现链接，再用浏览器读取和操作网页。 + +浏览器不可用时必须说明原因，不能隐瞒失败或声称已通过浏览器读取。该选择不缩减工具注册范围，实际调用由模型遵循提示词和用户任务安排。选择状态随会话最近一次输入设置恢复，切换智能体会清除；关闭浏览器选择不会改变其他开关。此功能需要使用 Agent 接口，普通问答接口拒绝该字段为 true 的请求。 + +### 标签组回收 + +默认标签组模式在结束任务时，先将明确归属于任务的标签移出分组，再关闭这些标签；不会按名称清理所有 WeKnora 分组，也不会移出用户后来加入的标签。取消分组失败时保留任务供重试，不报告清理成功。独立窗口模式不创建标签组。旧版本已经保存且关闭的历史分组不会追溯删除，需要用户在 Chrome 中选择“删除分组”；关闭书签栏显示仅隐藏入口，不等于删除。 + +Chrome 公开扩展 API 不提供直接删除历史已保存分组的接口。移出分组再关闭利用的是本地分组成员变更路径，参见 [Chromium
