anthropics/skills

This is a public repository from Anthropic that holds example Skills for Claude. In this context a Skill is a folder of instructions, scripts, and resources that Claude loads on demand when it is working on a specialized task. The README explains the idea simply: Skills teach Claude how to complete specific tasks in a repeatable way, such as creating documents that follow a company's brand guidelines, analyzing data using an organization's particular workflow, or automating personal tasks. The repository is organized so each Skill lives in its own folder containing a SKILL.md file with YAML frontmatter and the instructions Claude will follow. The frontmatter only requires two fields, a name and a description, which is also what tells Claude when to use the Skill. The repository groups examples into Creative and Design, Development and Technical, Enterprise and Communication, and Document Skills, plus a separate spec folder for the Agent Skills specification and a template folder you can copy as a starting point. The README also points out that the document creation and editing Skills behind Claude's built-in document capabilities, in subfolders for docx, pdf, pptx, and xlsx, are included as reference, most other Skills are released under Apache 2.0, while those four are source-available rather than open source. You would use this repository if you want to install ready-made Skills or learn the structure for writing your own. The README shows how to register the repo as a Claude Code plugin marketplace, install document or example Skill sets, or upload custom Skills through Claude.ai and the Claude API. The example Skills are written primarily in Python.
