## Example Types

### By Task Complexity

**Simple Prompts** (1-2 principles):
- Quick questions with context
- Straightforward requests
- Basic formatting needs

**Moderate Prompts** (3-5 principles):
- Multi-step tasks
- Technical explanations
- Structured outputs

**Complex Prompts** (6+ principles):
- Multi-phase projects
- Advanced reasoning
- Production-quality code

### By Improvement Type

**Clarity Improvements**:
- Vague → Specific (Principles 1, 4, 9, 21, 25)
- General → Targeted (Principles 2, 5, 10)

**Structure Improvements**:
- Unorganized → Structured (Principles 3, 8, 17)
- Single-shot → Step-by-step (Principles 12, 19)

**Quality Improvements**:
- Basic → Professional (Principles 11, 22, 26)
- Incomplete → Comprehensive (Principles 13, 20, 23)

## Using These Examples

Each example follows this format:

```markdown
### Example: [Task Type]

**Before** (Weak Prompt):
[Original problematic prompt]

**Issues Identified**:
- [Issue 1] - Violates Principle X
- [Issue 2] - Missing Principle Y

**After** (Strong Prompt):
[Improved optimized prompt]

**Principles Applied**:
1. **Principle X: [Name]** - How it was applied
2. **Principle Y: [Name]** - How it was applied

**Measured Improvements**:
- Response quality: [Metric]
- Task completion: [Metric]
- User satisfaction: [Metric]
```
