- **Constraints**: Specific requirements and formatting rules
- **Requirements**: Quality and content specifications
- **Output Format**: Desired structure and organization
- **Domain**: Context domain for better understanding

### **🎯 Example Output:**
```json
{
  "task": "create",
  "subject": "pet naming system",
  "constraints": [
    "10 unique names",
    "each labeled"
  ],
  "requirements": [
    "Provide comprehensive response",
    "Include specific examples", 
    "Structure output clearly",
    "Include actionable details"
  ],
  "outputFormat": {
    "structure": ["Overview", "Details", "Next Steps"],
    "type": "structured response",
    "includeExamples": true,
    "includeMeasurableOutcomes": true
  },
  "domain": "general",
  "originalPrompt": "create a pet naming system with 10 unique names"
}
```
