⚡ Quick Tips

Be specific about what you want
Include all necessary context
Specify the desired output format
Test and iterate on your prompts
Chapter 02

Being Clear and Direct

Eliminate ambiguity for better results

📊 Clarity Comparison

Unclear
Write something about dogs.
Clear
Write a 200-word informative paragraph about the benefits of dog ownership for families with children. Include at least 3 specific benefits and focus on emotional and social development.

🎯 Clarity Principles

✅ Do This

  • Use specific, concrete language
  • Provide detailed instructions
  • Define any ambiguous terms
  • Give examples when helpful

❌ Avoid This

  • Vague or general requests
  • Assuming Claude knows your context
  • Using jargon without explanation
  • Leaving room for interpretation

🔍 Clarity Checklist

Could this be interpreted differently?
Have I specified length, tone, and format?
Should I use bullet points for complex instructions?
Have I tested with edge cases?

Chapter 04

Separating Data from Instructions

Structure your prompts with XML tags

🏷️ XML Tag Structure

Structured Prompt Example 
You are a data analyst. Please analyze the following sales data and provide insights.

<data>
Q1 Sales: $50,000
Q2 Sales: $75,000
Q3 Sales: $60,000
Q4 Sales: $90,000
</data>

Provide:
1. Growth trends
2. Seasonal patterns
3. Recommendations for next year

✨ Benefits of Separation

Clarity

Instructions are distinct from content

Reliability

Reduces confusion about what to process

Scalability

Easy to swap different data sets

Debugging

Easier to identify issues

🏷️ Common XML Tags

<document> For text to analyze
<data> For datasets
<example> For reference examples
<context> For background information
Chapter 06

Precognition (Thinking Step by Step)

Guide Claude through complex reasoning

🧠 Thinking Tags Example

Step-by-Step Reasoning 
Please analyze this scenario and provide recommendations.

<thinking>
Let me think through this systematically:
1. What are the key factors?
2. What are the potential outcomes?
3. What are the risks and benefits?
</thinking>

Based on my analysis: [final response]

🎯 When to Use Thinking
