Anthropic Skills
Anthropic's official Agent Skills repo: the reference implementation of the standard.
About
Anthropic's official public skills repository (anthropics/skills, around 21,000 stars) contains the company's own implementation of Agent Skills for Claude. It ranges from creative applications (art, music, design) to technical tasks (testing web apps, MCP server generation) and enterprise workflows (communications, branding).
Notably, it includes the document creation and editing skills that power Claude's own document capabilities: docx, pdf, pptx, and xlsx skills are shared as source-available reference implementations. Many skills are open source under Apache 2.0.
Skills work across Claude.ai, Claude Code, and the API. Anthropic's disclaimer is worth heeding: these are demonstration and educational implementations, and behaviors may differ from what Claude ships natively. Always test thoroughly before relying on them for critical work.
