## Best Practices

1. **Clear Prompts**: Be specific about requirements
2. **Context**: Provide relevant context and constraints
3. **Examples**: Include input/output examples when applicable
4. **Verification**: Always review and test generated code
5. **Iteration**: Refine prompts based on initial results

## Limitations and Considerations

- Generated code should be reviewed before production use
- Complex mathematical proofs may require human verification
- Performance optimization may need domain-specific tuning
- Security-critical code requires additional audit
- Large-scale system designs need architectural review
