+
+## 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]
+```
+
+## Quick Reference: Principle Categories
+
+### Content Principles (What to say)
+- **1-2**: Clarity and audience targeting
+- **9-10**: Directness and explicitness
+- **21**: Detail level
+- **25**: Requirements specification
+
+### Structure Principles (How to organize)
+- **3**: Task breakdown
+- **8**: Delimiters and sections
+- **17**: Structured input/output
+
+### Reasoning Principles (How to think)
+- **12**: Step-by-step instructions
+- **19**: Chain-of-thought
+- **20**: Few-shot examples
+
+### Style Principles (How to express)
