This repository is a curated list of Skills for Claude, the AI assistant made by Anthropic. A Claude Skill is a folder containing instructions, scripts, and supporting files that teach Claude how to perform a specific task in a repeatable way. When you start a conversation and describe what you want to do, Claude can detect whether any available Skill applies and load only the relevant one rather than loading everything at once. The list is organized into official Skills published by Anthropic and community-contributed Skills. Official Skills cover working with common file formats: Word documents, PDFs, PowerPoint presentations, and Excel spreadsheets. There are also Skills for generating visual art, building web interfaces, writing internal communications, testing web applications with browser automation, and creating new Skills from scratch via a guided question-and-answer process. Community Skills range from collections of general-purpose development aids (with commands for brainstorming and planning) to specialized tools like iOS app testing, web security fuzzing during penetration tests, scientific data libraries, and animated HTML slide presentations. The README includes a warning that Skills can execute arbitrary code inside Claude's environment, and links to a security guidance section. Skills can be used in three places: the Claude.ai web interface (through a settings toggle), the Claude Code command-line tool (via a plugin install command), and directly through the Anthropic API for developers building applications on top of Claude. The repository itself does not contain Skills, it collects links and descriptions of Skills hosted elsewhere, following the "awesome list" convention common in open-source communities. Anyone can submit a pull request to add a new entry.
