README

What it is

Anthropic's public skills repository is the safest starting point for understanding the Agent Skills format. The README describes skills as self-contained folders with SKILL.md, optional scripts, and resources that Claude loads dynamically for specialized tasks.

Why it is useful

Use this repository as a reference when you need production examples instead of theoretical prompts. It includes simple demonstration skills and more complex document-related skills for docx, pdf, pptx, and xlsx.

Best uses

  • Learn how a real SKILL.md is structured.
  • Copy patterns for scripts/, references/, and assets/.
  • Compare your own skills against the official baseline before publishing.

Notes

Some document skills are source-available rather than open source. Check the license and README before copying code or redistributing derived work.
