This repository contains skills that demonstrate what's possible with Claude's skills system. These skills range from creative applications (art, music, design) to technical tasks (testing web apps, MCP server generation) to enterprise workflows (communications, branding, etc.). Each skill is self-contained in its own folder with a SKILL.md file containing the instructions and metadata that Claude uses. Browse through these skills to get inspiration for your own skills or to understand different patterns and approaches. Many skills in this repo are open source (Apache 2.0). We've also included the document creation & editing skills that power Claude's document capabilities under the hood in the skills /docx , skills /pdf , skills /pptx , and skills /xlsx subfolders. These are source-available, not open source, but we wanted to share these with developers as a reference for more complex skills that are actively used in a production AI application. https://github.com/anthropics/skills #skills #claude Claude Claude can now create and edit files | Claude Describe what you need and get back ready-to-use spreadsheets, documents, presentations, and PDFs instead of just text responses. Update: Now generally available for paid plans with net network and egress controls (October 21, 2025).
