In simple English
This is a collection of guides and scripts made by Anthropic. They teach the Claude artificial intelligence assistant how to perform specific jobs. These include writing files, analyzing data, and designing web pages. You can use them to make your AI assistant follow your exact rules and workflows. It costs nothing to download, but you need access to Claude to run the skills.
What it is
This repository contains open source and reference skills for Claude, structured as folders with instruction files and scripts. Each folder gives the AI model step-by-step guidance on how to handle documents, write code, or format outputs.
What it is good for
Solo builders who want to make Claude follow consistent company guidelines, generate specific document types like PDFs, or run custom workflows without repeating instructions.
Summary (Key Points)from the README
Key features
- Self-contained skill folders: Each skill sits in its own folder with a `SKILL.md` file holding the instructions and metadata Claude uses.
- Broad example range: Skills cover creative work (art, music, design), technical tasks (testing web apps, MCP server generation), and enterprise workflows (communications, branding).
- Document skills: The `docx`, `pdf`, `pptx`, and `xlsx` subfolders contain the document creation and editing skills behind Claude's document capabilities.
- Simple skill format: A skill needs only a folder and a `SKILL.md` with YAML frontmatter; the frontmatter requires just `name` and `description`.
- Starter template: A `template` folder provides a skill template to copy when building a new skill.
- Specification included: A `spec` folder contains the Agent Skills specification.
- Plugin marketplace: The repo can be registered as a Claude Code Plugin marketplace, with `document-skills` and `example-skills` plugins available.
- Open-source licensing for most skills: Many skills are published under Apache 2.0.
- Partner examples: Partner skills, such as the Notion skills linked in the README, show how skills can teach Claude specific software.
Ways to install
| Platform or method | What it needs | Effort |
|---|---|---|
| Claude Code (plugin marketplace) | Claude Code; run the marketplace add command, then install the `document-skills` or `example-skills` plugin | Low: a few plugin commands |
| Claude.ai | A paid plan; the example skills are already available, and custom skills are uploaded by following the linked guide | Low: no install needed for example skills |
| Claude API | API access; upload Anthropic's pre-built skills or custom skills per the Skills API Quickstart | Higher: requires API integration; the README gives no detail beyond the quickstart link |
Important
- Demonstration only: The README states the skills are provided for demonstration and educational purposes only.
- Behavior may differ: The implementations and behaviors you get from Claude may differ from what the skills show.
- Test before relying on them: The README says to test skills thoroughly in your own environment before using them for critical tasks.
- Source-available, not open source: The `docx`, `pdf`, `pptx`, and `xlsx` skills are source-available and not open source, so check the license of each skill before reuse.
- Paid plan for Claude.ai: Example skills are available to paid Claude.ai plans, per the README.
Written by an AI model from the project’s README; not part of the review, and it can be wrong.
- Ready-made guides for common tasks like creating Word and PDF files.
- Easy to customize by editing simple text files and folder structures.
- Works directly inside Claude Code and the official API tools.
- Requires an active account or API access for the Claude artificial intelligence assistant.
- Some advanced document tools use a restricted licence instead of open source.
- Relies on remote AI services, so it will not run offline on your own hardware.
