Anthropic's Prompt Engineering Interactive Tutorial

This is Anthropic's official Prompt Engineering Interactive Tutorial — the single best free resource for anyone learning how to write effective prompts with Claude.

What it covers: • The fundamentals of prompt structure and clarity • How to use examples (few-shot prompting) to guide Claude's responses • Role prompting and persona techniques • Using XML tags to structure complex prompts • Chain of thought and step-by-step reasoning • Prompt chaining for breaking down complex tasks • Advanced techniques like tool use and function calling

Why this is great for beginners: The tutorial is designed as a hands-on, interactive experience. Each concept is paired with real examples you can run and modify yourself. It starts from the absolute basics — like how to write a clear instruction — and gradually builds up to advanced prompt engineering patterns used in production applications.

Use cases: • Learning to write better prompts for everyday Claude use • Understanding how to get more consistent, accurate outputs • Building reusable prompt templates for your projects • Preparing for building apps and workflows with the Claude API

This is the resource Anthropic themselves recommend as the starting point for prompt engineering, and it's completely free and open source on GitHub.
