 ## 通用特性
 - ✅web_execute_js**完美支持顶层await**（v0.4+），可直接`await fetch()`/`await new Promise()`等
   - ⚠使用await时需**显式`return`**才能拿到返回值（底层async包裹，不写return则返回null）
+- ✅web_scan**自动穿透同源iframe**：无需手动操作，scan直接递归输出iframe内部DOM。跨域iframe则需CDP或postMessage（见下方章节）
 
 ## 限制(isTrusted)
 - JS dispatch的事件`isTrusted=false`，敏感操作(文件上传/部分按钮)会被浏览器拦截

 # Web 工具链初始化执行 SOP
 
+⚠ **当前只需安装 `assets/tmwd_cdp_bridge` Chrome 扩展即可，Tampermonkey 方案将在未来移除。**
+
 若 web_scan 和 web_execute_js 已测试可用，无需执行此 SOP。
 仅供初始安装时，code_run 可用但 web 工具尚未配置的场景。
