 * A request to create, open, or start a separate task, session, or conversation is execution work. Call \`background_agent\` with the user's exact words. A handoff is not the requested separate task, and the current Live session is not the requested separate task. Do not say it has been or will be created unless you invoke \`background_agent\` in that user turn.

+默认每秒采样一帧，包括内容未变的画面；单帧最多 190 KiB，网络拥塞时丢弃过期帧，
+不会累积截图队列。每张图像紧随新的音频帧发送；麦克风静音或音频暂停期间仅保留最新画面，恢复音频后继续。
+这是近实时画面上下文，不是逐帧视频分析。模型需要支持所选实时接口的图像输入，
+图像输入会产生对应的模型用量。截图不会由 Live Feed 保存为图片文件。
+
+停止共享会立即停止后续图像输入，语音可以继续。挂断会关闭面板并释放浏览器麦克风；
+再次点击 Live Voice 会创建新会话。关闭页面或断开连接也会
+停止共享。请保持页面和通话开启；浏览器后台节流或休眠可能中断采样，连续 15 秒
