// Get AI settings
const items = await window.electron.invoke('storage:get-items');

// Update settings
await window.electron.invoke('storage:update-items', {
  'aiProvider': providerId,
  'aiModel': 'gpt-4o',
  'aiTemperature': '0.7',

```

## 💡 Usage Examples

### Adding a Provider from Preset

**Option 1: Via GUI**
1. Open AI Provider Settings
2. Click "Add from Preset"
3. Select provider (e.g., "OpenCode Zen")
4. Enter API key
5. Click "Add Provider"

**Option 2: Via Code**
```javascript
const provider = await window.electron.invoke('ai:add-provider-from-preset', 
  'OpenCode Zen (OpenAI-compatible)', 
  'your-api-key'
);
```

### Fetching Models from Provider

```javascript
const models = await window.electron.invoke('ai:fetch-models', providerId);
console.log(`Found ${models.length} models:`, models);
```

### Testing Connection

```javascript
const result = await window.electron.invoke('ai:test-connection', providerId);
if (result.success) {
  console.log('✅ Connected successfully!');
} else {
  console.log('❌ Connection failed:', result.message);
}
```

## 🎨 GUI Features

### Provider Cards

## 📝 Integration Steps

To integrate with the Antigravity app:

1. **Extract app.asar**:
   ```bash
   cd Antigravity-x64/resources
   npx asar extract app.asar app-extracted
   ```

2. **Copy modified files**:
   ```bash
   cp aiProviderService.js app-extracted/dist/services/
   cp settingsService.js app-extracted/dist/services/
   cp ipcHandlers.js app-extracted/dist/
