Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| navigateA | 导航到 URL。默认当前 tab；new_tab=true 新开 tab 并自动切换为操作指针。返回当前 tab 信息与全部 tabs 清单（switch 需要 tab_id）。 |
| execute_jsA | 在当前 tab 执行 JavaScript 代码。⚠️ 必须使用 return 语句返回结果。preset='dom_tree' 时 code 改为传 JSON 参数对象 {"max_depth":5,"include_text":true,"max_text_length":50,"selector":null}，直接输出 DOM 结构树。 |
| run_cdpA | 对当前 tab 透传 Chrome DevTools Protocol 命令。method 如 'Page.captureScreenshot'，params 为参数对象。命令始终作用于当前 tab，无需 attachToTarget（Target.createTarget/activateTarget 会自动切换操作 tab）。详见 get_manual。 |
| run_drission_codeB | 执行 DrissionPage Python 代码（server 进程内，完整能力底座）。预置变量：page=当前tab、browser=浏览器对象、context=跨调用持久字典、DOM_TREE_JS=DOM树JS模板。预置函数：switch_tab(tab_id)、tabs()、relaunch(**opts)。⚠️ 必须用 return 返回结果。 |
| captureA | 网络抓包三合一。action='start'：在当前 tab 启动监听（⚠️ 必须在触发请求之前调用；监听挂载在该 tab，不随指针迁移）；action='get'：拉取结果（概览直接返回，完整数据落盘 JSON 供 read）；action='stop'：停止并清空。 |
| get_manualB | 返回内置编写手册：定位语法、元素动作、等待、tab 管理、抓包、CDP 高频配方、启动定制等速查。 |
| close_browserC | 关闭浏览器实例 |

TDQS
Scored across 7 tools
run_cdp, execute_js, and run_drission_code all provide code/protocol execution on the current tab, creating overlap that could confuse an agent. get_manual and close_browser are distinct, but the three execution tools lack clear boundary guidance.
Mostly consistent snake_case verb_noun style (run_cdp, get_manual, close_browser, run_drission_code, execute_js), with 'capture' and 'navigate' as minor single-verb exceptions.
Seven tools are well-scoped for a Chrome automation server, covering navigation, JS execution, CDP, network capture, manual lookup, and browser lifecycle without bloat.
Covers the core lifecycle: launch/close, navigate/tabs, JS/CDP execution, network capture, and a manual. Minor gaps exist around explicit tab management (though navigate and run_drission_code provide switch_tab/tabs), and no dedicated element-click/type tools, but coverage is strong for the stated purpose.
