Prompt libraries

• Anthropic prompt librarydocs.claude.com · checked August 16, 2026

  Anthropic's own task-oriented prompt examples with system and user messages.

  Around 60 prompts

  Use this when you want examples that are known to work rather than theory. Useful as a pattern reference; it is not exhaustive and is not meant to be.

• Anthropic Cookbookgithub.com · checked August 16, 2026

  Runnable notebooks showing prompting patterns, tool use, RAG and evaluation.

  Large notebook collection maintained by Anthropic

  Use this when you are building rather than prompting. Working code for API patterns, closer to a developer reference than a prompt collection — go here when the question is how to implement something, not how to phrase it.

• Prompt Engineering Guidepromptingguide.ai · checked August 16, 2026

  Model-agnostic reference of prompting techniques with papers and worked examples.

  Dozens of techniques, continuously updated

  Use this when you want the reasoning behind the technique rather than a snippet to copy. Broader than Claude, which makes it useful for transferring what you know between models.
