Anthropic Prompt Engineer
Master the art and science of prompt engineering with Anthropic's proven techniques. Generate new prompts from scratch or improve existing ones using best practices for Claude AI models (Claude 4.x, Sonnet, Opus, Haiku).
What This Skill Does
Helps you create and optimize prompts for Claude AI using Anthropic's official techniques:
- Generate new prompts - Build effective prompts from requirements
- Improve existing prompts - Optimize prompts for better results
- Apply best practices - Use proven techniques from Anthropic
- Avoid common mistakes - Prevent hallucinations and unclear outputs
- Optimize for Claude 4.x - Leverage latest model capabilities
- Structure complex prompts - Build multi-step, production-ready prompts
Why Prompt Engineering Matters
Without proper prompting:
- Inconsistent or incorrect outputs
- Hallucinations and made-up information
- Unclear or verbose responses
- Wasted tokens and API calls
- Poor performance on complex tasks
- Difficulty reproducing results
With engineered prompts:
- Precise, reliable outputs
- Factual, grounded responses
- Clear, formatted results
- Efficient token usage
- Excellent complex task performance
- Reproducible, production-ready results
Quick Start
Generate a New Prompt
Using the anthropic-prompt-engineer skill, create a prompt that:
- Extracts structured data from customer emails
- Returns JSON format
- Handles missing information gracefully
- Includes 2 examples
Improve an Existing Prompt
Using the anthropic-prompt-engineer skill, improve this prompt:
"Analyze this code and tell me if there are bugs"
Make it more effective using Anthropic's best practices.
Core Techniques Summary
1. Be Clear and Direct
Provide explicit, unambiguous instructions. Claude 4.x excels with precise direction.
2. Use XML Tags for Structure
Organize prompts with semantic tags like <instructions>, <example>, <context>.
3. Chain of Thought (CoT)
Ask Claude to think step-by-step for complex reasoning.
4. Prefilling
Start Claude's response to guide format and style.
5. Few-Shot Examples
Provide 2-5 diverse examples showing the pattern you want.
6. Role Assignment
Give Claude a specific role or persona for appropriate context.

Usage Examples
Example 1: Generate a Data Extraction Prompt
Create a prompt that extracts names, emails, and phone numbers from business cards.
Example 2: Improve a Vague Prompt
Transform "Write about machine learning" into a structured, effective prompt.
Example 3: Debug a Failing Prompt
Fix inconsistent outputs by adding structure, examples, and format specification.
Best Practices Checklist
- Instructions are clear and specific
- Output format is explicitly defined
- Examples align with desired behavior
- XML tags separate different sections
- Context is minimal but sufficient
- Edge cases are addressed
- Tested on diverse inputs
- Token usage is optimized
Key Principles
- Empirical Approach - Test, measure, iterate
- Context as Resource - Every token counts
- Clarity Over Cleverness - Explicit instructions work best
- Examples Teach Best - Show, don't just tell
- Structure Helps - Organization reduces confusion
- Iteration Improves - Refine based on results
Summary
Master prompt engineering to create:
- Reliable and consistent outputs
- Production-ready prompts
- Token-efficient solutions
- Easy to maintain systems
Apply Anthropic's proven techniques for best results.
Remember: Good prompts are engineered, not guessed.
