|
|
- **Result Display**: Dynamic rule display with quality indicators
|
|
- **User Interactions**: Copy, use, and regenerate functionality
|
|
|
|
## Implementation Details
|
|
|
|
### AI Service Integration
|
|
|
|
#### Configuration
|
|
The AI service is configured through environment variables:
|
|
```bash
|
|
AI_SERVICE_URL=https://api.openai.com/v1
|
|
AI_SERVICE_API_KEY=your-api-key
|
|
AI_MODEL=gpt-3.5-turbo
|
|
AI_TIMEOUT=30
|
|
AI_MAX_RETRIES=3
|
|
AI_CACHE_TTL=3600
|
|
```
|
|
|
|
#### Rule Generation
|
|
The service supports two modes:
|
|
1. **Single Rule Generation**: Creates one optimized rule based on folder context
|
|
2. **Multiple Rule Options**: Generates 5 different rule variations for user selection
|
|
|
|
#### Quality Assessment
|
|
Rules are evaluated on:
|
|
- Specificity (20 points)
|
|
- Action-orientation (15 points)
|
|
- Length optimization (20 points)
|
|
- Folder relevance (15 points)
|
|
- Grammar and structure (10 points)
|
|
- Pattern matching (10 points)
|
|
|
|
### Caching Strategy
|
|
|
|
#### Cache Key Generation
|
|
```python
|
|
cache_key = hashlib.md5(f"{folder_name}:{folder_type}:{rule_type}").hexdigest()
|
|
```
|
|
|
|
#### Cache Management
|
|
- TTL-based expiration (default: 1 hour)
|
|
- Automatic cleanup of expired entries
|
|
- User-specific isolation
|
|
- Performance optimization for repeated requests
|
|
|
|
### Error Handling
|
|
|
|
#### Fallback Mechanisms
|
|
1. **Primary Fallback**: Default rule templates based on folder type
|
|
2. **Secondary Fallback**: Cached responses when available
|
|
3. **Graceful Degradation**: Manual entry option always available
|
|
|
|
#### Error Categories
|
|
- Network errors (connection timeouts, DNS failures)
|
|
- Authentication errors (invalid API keys, rate limits)
|
|
- Service errors (AI service unavailability, timeouts)
|
|
|
|
## User Interface
|
|
|
|
### Modal Enhancements
|
|
The folder creation modal now includes:
|
|
- **AI Generation Buttons**: Single rule and multiple options
|
|
- **Loading States**: Visual feedback during AI processing
|
|
- **Result Display**: Dynamic content with quality indicators
|
|
- **Interactive Elements**: Copy, use, and regenerate functionality
|
|
|
|
### Accessibility Features
|
|

|
|
- **Keyboard Navigation**: Full keyboard support
|
|
- **Screen Reader Announcements**: Status updates for actions

|
|
- **Percentage Display**: 0-100% quality score
|
|
- **Feedback Text**: Explanations of quality assessment
|
|
