## KEY FEATURES IMPLEMENTED

### 1. Universal Content Model
- All content types use the same `Content` model
- `entity_type` field distinguishes content types
- `json_blocks` stores structured content (features, specifications, categories, etc.)
- `structure_data` stores metadata (product_type, price_range, taxonomy_type, etc.)

### 2. Type-Specific Prompts
- Product prompts focus on features, specifications, pricing, benefits
- Service prompts focus on benefits, process, pricing, FAQ
- Taxonomy prompts focus on categories, tags, hierarchy organization

### 3. Enhanced Linking
- **Product Linking**: Links to related products (same type), related services
- **Taxonomy Linking**: Links to related taxonomies, content within categories

### 4. Enhanced Optimization
- **Product Optimization**: Includes `product_completeness` score (pricing, features, specs)
- **Taxonomy Optimization**: Includes `taxonomy_organization` score (categories, tags, hierarchy)

### 5. API Endpoints
- All three content types have dedicated generation endpoints
- Consistent request/response format
- Proper error handling and validation

## NEXT STEPS

### To Apply Changes:

1. **Run Migration**:
   ```bash
   python manage.py migrate writer
   ```

2. **Run Tests**:
   ```bash
   python manage.py test igny8_core.business.content.tests.test_universal_content_types
   ```

3. **Verify API Endpoints**:
   - Test product generation: `POST /api/v1/writer/content/generate_product/`
   - Test service generation: `POST /api/v1/writer/content/generate_service/`
   - Test taxonomy generation: `POST /api/v1/writer/content/generate_taxonomy/`
