 This skill works best when the agent can reuse your current Chrome session through Chrome DevTools MCP. For live browser automation, set up Chrome remote debugging first, then configure the MCP server to attach automatically to the running browser.
 
+> [!IMPORTANT]
+> Make sure Chrome is already running before you start. Otherwise, the agent may be unable to attach to your current browser session and may fall back to a separate isolated browser session instead.

 In Chrome (>=144), navigate to `chrome://inspect/#remote-debugging` to enable remote debugging.

 当智能体可以通过 Chrome DevTools MCP 复用你当前的 Chrome 会话时，该 skill 的效果最好。若要进行实时浏览器自动化，请先设置 Chrome 远程调试，然后配置 MCP 服务器，使其能自动连接到正在运行的浏览器。
 
+> [!IMPORTANT]
+> 开始前请先确保 Chrome 已经在运行。否则智能体可能无法连接到当前的浏览器会话，并可能回退到一个独立的隔离浏览器会话。
+
 在 Chrome (>=144) 中，访问 `chrome://inspect/#remote-debugging` 以启用远程调试。
