## Best Practices

✅ **Do**:
- Be specific about dimensions and format
- Describe visual style clearly (modern, minimalist, professional)
- Specify colors using hex codes or names
- Include key elements that must appear
- Mention the intended use case
- Provide context about brand/aesthetic

❌ **Don't**:
- Use vague descriptions ("make it nice")
- Forget to specify dimensions
- Assume default style preferences
- Skip color specifications
- Omit output location

### Example: Good vs Bad Prompts

**❌ Bad Prompt**:
```
"Create a diagram of our system"
```

**✅ Good Prompt**:
```
"Create a technical architecture diagram showing:
- 3 microservices (API, Auth, Database)
- AWS infrastructure (EC2, RDS, S3)
- External APIs (Stripe, SendGrid)

Style: Clean, professional, modern
Colors: Blue for services, green for databases
Format: PNG, 1920x1080
Layout: Left-to-right flow with clear connections

Output: docs/system-architecture.png"
