/erne-setup-device — Setup Device Control

You are executing the /erne-setup-device command. This is script-driven — it sets up the agent-device MCP server.

What This Does

Installs and configures the agent-device MCP server so commands like /erne-debug, /erne-perf, /erne-component, and /erne-deploy gain visual device interaction capabilities.

Process

Step 1: Check Prerequisites

# iOS: Check for Xcode and simulator
xcodebuild -version
xcrun simctl list devices

# Android: Check for Android Studio and emulator
adb version
emulator -list-avds

Step 2: Install agent-device MCP

Check if already configured in .claude/settings.json:

{
  "mcpServers": {
    "agent-device": {
      "command": "npx",
      "args": ["-y", "agent-device"]
    }
  }
}

If not present, add the configuration.

Step 3: Verify Connection

# Boot a simulator (iOS)
xcrun simctl boot "iPhone 16 Pro"

# Or start an emulator (Android)
emulator -avd Pixel_8_API_35 &

Test that agent-device can:

• Take a screenshot
• Detect booted device
• Perform a tap action

Step 4: Configure Command Integration

After setup, these commands gain enhanced capabilities:

| Command | Enhancement | |---------|-------------| | /erne-debug | Screenshot reproduction steps, tap through UI | | /erne-perf | Measure real FPS, capture actual jank frames | | /erne-component | Render on device, visual verification screenshot | | /erne-deploy | Launch preview build, verify UI before submit | | /erne-build-fix | Build, install, and launch to verify fix |

Output

## agent-device Setup Complete

### Status

Troubleshooting

| Problem | Solution | |---------|----------| | iOS simulator not found | Install Xcode, run xcode-select --install | | Android emulator not found | Install Android Studio, create AVD in AVD Manager | | agent-device fails to connect | Check MCP server config in .claude/settings.json | | Screenshots are black | Wait for device to finish booting, retry |
