# android-device-automation

This skill drives an Android device over ADB from screenshots: taps, swipes, text input, app launches. Useful for checking a mobile app without clicking through it by hand.

## What it does

The skill runs through `npx -y @midscene/android@1` and needs no DOM or accessibility labels — the agent looks at a screenshot and decides what to press. Commands mirror Midscene MCP tools: `connect` attaches a device, `launch` opens an app or URL, `take_screenshot` captures the screen, `act` performs an action described in plain language, `assert` checks the visible state. A single `act` covers tapping, long-press, typing, clearing text, scrolling, swiping, dragging, two-finger zoom and system navigation such as Back or Home.

You need a model with strong visual grounding before anything runs. Four variables — `MIDSCENE_MODEL_API_KEY`, `MIDSCENE_MODEL_NAME`, `MIDSCENE_MODEL_BASE_URL`, `MIDSCENE_MODEL_FAMILY` — go into the system environment or a `.env` file in the working directory, which Midscene loads on its own. If the model is missing, the skill asks you to set it up. The `--device-id` flag picks one device from `adb devices`, and `--use-scrcpy` switches to accelerated screenshots — pass it on every command, since CLI calls keep no state.

One hard rule: never run Midscene commands in the background and never chain them. Each runs synchronously so you can read the screenshot before the next step. A typical command takes about a minute, a complex `act` longer. Worth knowing if you like firing off parallel jobs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add web-infra-dev/midscene-skills --skill android-device-automation -a claude-code
```
```bash
npx skills add web-infra-dev/midscene-skills --skill android-automation -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/android-automation/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/android-automation/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add web-infra-dev/midscene-skills --skill android-automation -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/android-automation/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add web-infra-dev/midscene-skills --skill android-automation -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/android-automation/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install web-infra-dev/midscene-skills android-automation
```

2. **Manually: put the files in place**
- File: `.github/skills/android-automation/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add web-infra-dev/midscene-skills --skill android-automation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/web-infra-dev/midscene-skills --path skills/android-automation
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/android-automation/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add web-infra-dev/midscene-skills --skill android-automation -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/web-infra-dev/midscene-skills/tree/HEAD/skills/android-automation/SKILL.md

## When to use it
- test a mobile app on a real device without manual tapping
- launch an app and reach a specific screen from a description
- type into a field and confirm the text landed
- capture a screenshot and read what is on it
- run an `adb shell` command for lower-level checks

## Example prompts
- connect to emulator-5554 and open Wi-Fi settings, tell me the connected network name
- type hello world in the search field and press Enter
- take a screenshot and describe what is on the screen

# Android Device Automation

> **CRITICAL RULES — VIOLATIONS WILL BREAK THE WORKFLOW:**
>
> 1. **Never run midscene commands in the background.** Each command must run synchronously so you can read its output (especially screenshots) before deciding the next action. Background execution breaks the screenshot-analyze-act loop.
> 2. **Run only one midscene command at a time.** Wait for the previous command to finish, read the screenshot, then decide the next action. Never chain multiple commands together.
> 3. **Allow enough time for each command to complete.** Midscene commands involve AI inference and screen interaction, which can take longer than typical shell commands. A typical command needs about 1 minute; complex `act` commands may need even longer.
> 4. **Always report task results before finishing.** After completing the automation task, you MUST proactively summarize the results to the user — including key data found, actions completed, screenshots taken, and any relevant findings. Never silently end after the last automation step; the user expects a complete response in a single interaction.
