Anthropic has published its complete interactive prompt engineering tutorial on GitHub (anthropics/prompt-eng-interactive-tutorial), now at 38K stars and 4.2K forks. The course has 9 chapters plus an advanced appendix, each with exercises and an answer key.
The chapters that matter most for agent builders:
- Separating data from instructions so pasted content isn't read as a command
- Thinking step by step before the agent acts
- Few-shot examples to lock in output format
- Avoiding hallucinations
- Bonus lessons on chaining prompts, tool use, and search
