GUI Mobile Use
Use the gui_execute tool to control a connected Android or HarmonyOS phone through natural language instructions. The tool captures the phone screen, reasons about it with a vision-language model, and performs actions (tap, swipe, type, home, back, etc.) in a loop until the task completes.
Prerequisites
- ADB installed and on PATH (
adb for Android, hdc for HarmonyOS)
- Phone connected via USB with USB debugging enabled
- ADB Keyboard installed and enabled on the device
Usage
Basic
gui_execute(task="Open WeChat and send 'I will be late' to Zhang San")
With step limit
gui_execute(task="Search for Bluetooth headphones on Taobao and add to cart", max_steps=80)
Examples
| User says | Tool call |
|---|
| 帮我打开微信给张三发消息说我晚点到 | gui_execute(task="打开微信给张三发一条消息说我晚点到") |
| Turn on Bluetooth on my phone | gui_execute(task="Open Settings and turn on Bluetooth") |
| 帮我看看手机上有什么新通知 | gui_execute(task="下拉通知栏查看最新通知并汇报内容") |
| Open YouTube and search for cooking videos | gui_execute(task="Open YouTube app and search for cooking videos") |
| 截个屏看看手机现在显示什么 | gui_execute(task="截取当前屏幕截图并描述屏幕内容") |
| 帮我在淘宝搜蓝牙耳机加入购物车 | gui_execute(task="打开淘宝搜索蓝牙耳机，选择第一个商品加入购物车", max_steps=80) |
Parameters
| Parameter | Type | Required | Default | Description |
|---|
task | string | ✅ | — | Natural language description of what to do on the phone |
max_steps | integer | ❌ | 50 | Max number of GUI action steps (1–200) |
Tips
- Be specific in task descriptions — include app names, contact names, exact text to type.
- Set higher max_steps for multi-step flows (e.g. navigating through several screens).
- The tool will automatically check that ADB is installed, the device is connected, and ADB Keyboard is available before attempting any action.
- If an error is returned about missing ADB Keyboard, guide the user to install it.
Configuration
The GUI tool is configured in ~/.nanobot/config.json under tools.gui:
{
"tools": {
"gui": {
"enable": true,
"deviceType": "adb",
"deviceId": null,
"maxSteps": 50,
"useExternalModel": true,
"guiBaseUrl": "https://open.bigmodel.cn/api/paas/v4/",
"guiApiKey": "YOUR_API_KEY",
"guiModelName": "autoglm-phone",
"promptTemplateLang": "cn",
"promptTemplateStyle": "autoglm",
"traceEnabled": false,
"traceDir": "gui_trace"
| Config Key | Description |
|---|
enable | Enable/disable the GUI tool |
deviceType | adb (Android) or hdc (HarmonyOS) |
deviceId | Specific device serial (auto-detect if null) |
maxSteps | Default max steps per task |
useExternalModel | Use external GUI VLM (true) or nanobot model (false) |
guiBaseUrl | API base URL for the external GUI model |
guiApiKey | API key for the external GUI model |
guiModelName | Model name (e.g. autoglm-phone) |
promptTemplateLang | Prompt language: cn or en |
promptTemplateStyle | Prompt template: autoglm / uitars / qwenvl / maiui / guiowl |
traceEnabled | Save execution trace to traceDir |
traceDir | Directory for episode folders and screenshots |
skillMode | Runtime skill mode: off / trace / reuse / evolve |
skillsDir | ClawGUI-Skills store directory |
skillRetrievalThreshold | Minimum score for reusing an existing skill |
skillMaxContextChars | Character budget for injected skill context |
skillMaxIterations | Maximum immediate retry attempts after an evolve-mode revision |
skillRequireReview |
Runtime Skills
skillMode controls ClawGUI-Skills runtime packages, not nanobot's static SKILL.md files. In reuse mode the GUI tool retrieves a matching skill package and injects compact execution guidance. In evolve mode it can also materialize a new package, diagnose failed traces, revise plan.md / backup.md / recover.md, and add failure_examples/.
Troubleshooting
| Error | Solution |
|---|
| ADB not found | Install: brew install android-platform-tools (macOS) or apt install android-tools-adb (Linux) |
| No devices connected | Connect phone via USB, enable USB debugging in Developer Options |
| ADB Keyboard not installed | Install APK from https://github.com/senzhk/ADBKeyBoard |
| External model API key missing | Set guiApiKey in config.json |
| Task timeout / too many steps | Increase max_steps or simplify the task description |
