Anthropic Agent Skills vs Expo Skills

Note: This repository contains Anthropic's implementation of skills for Claude. For information about the Agent Skills standard, see agentskills.io.

Skills

Skills are folders of instructions, scripts, and resources that Claude loads dynamically to improve performance on specialized tasks. Skills teach Claude how to complete specific tasks in a repeatable way, whether that's creating documents with your company's brand guidelines, analyzing data using your organization's specific workflows, or automating personal tasks.

About This Repository

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 also open source (Apache 2.0), and we wanted to share them with developers as a reference for more complex skills that are actively used in a production AI application.

Disclaimer

These skills are provided for demonstration and educational purposes only. While some of these capabilities may be available in Claude, the implementations and behaviors you receive from Claude may differ from what is shown in these skills. These skills are meant to illustrate patterns and possibilities. Always test skills thoroughly in your own environment before relying on them for critical tasks.

Try in Claude Code, Claude.ai, and the API

Claude Code

You can register this repository as a Claude Code Plugin marketplace by running the following command in Claude Code:

/plugin marketplace add anthropics/skills

Then, to install a specific set of skills:

1. Select Browse and install plugins
2. Select anthropic-agent-skills
3. Select document-skills or example-skills
4. Select Install now

Alternatively, directly install either Plugin via:

/plugin install document-skills@anthropic-agent-skills
/plugin install example-skills@anthropic-agent-skills

After installing the plugin, you can use the skill by just mentioning it. For instance, if you install the document-skills plugin from the marketplace, you can ask Claude Code to do something like: "Use the PDF skill to extract the form fields from path/to/some-file.pdf"

Claude.ai

These example skills are all already available to paid plans in Claude.ai.

To use any skill from this repository or upload custom skills, follow the instructions in Using skills in Claude.

Claude API

You can use Anthropic's pre-built skills, and upload custom skills, via the Claude API. See the Skills API Quickstart for more.

Creating a Basic Skill

Skills are simple to create - just a folder with a SKILL.md file containing YAML frontmatter and instructions. You can use the template-skill in this repository as a starting point:

---
name: my-skill-name
description: A clear description of what this skill does and when to use it
---

## My Skill Name

[Add your instructions here that Claude will follow when this skill is active]

## Examples
- Example usage 1
- Example usage 2

## Guidelines
- Guideline 1
- Guideline 2

The frontmatter requires only two fields:

• name - A unique identifier for your skill (lowercase, hyphens for spaces)
• description - A complete description of what the skill does and when to use it

The markdown content below contains the instructions, examples, and guidelines that Claude will follow. For more details, see How to create custom skills.

Partner Skills

Skills are a great way to teach Claude how to get better at using specific pieces of software. As we see awesome example skills from partners, we may highlight some of them here:

• Notion - Notion Skills for Claude

Expo Skills

Official AI agent skills from the Expo team for building, deploying, upgrading, and debugging Expo apps.

How It Works

Skills give AI agents focused Expo knowledge: when to use Expo APIs, how to structure common workflows, and which Expo, EAS, React Native, iOS, and Android constraints matter. Expo documentation, Expo CLI, and EAS CLI remain the source of truth; these skills help agents apply them correctly.

Installation

For Claude Code or Codex, install the plugin so updates are handled by the official plugin marketplace. For Cursor, OpenCode, and other AI coding agents, use the skills CLI.

Skills CLI

Install all Expo skills with the skills CLI:

npx skills@latest add expo/skills --skill '*'

This selects every Expo skill without selecting every agent. The CLI will still ask where to install them; to target one agent directly, add --agent <agent>.

For most agents, this is the only install command you need. Run it from the project root, then restart or refresh your agent session so it can discover the installed SKILL.md files.

Claude Code Plugin

Install from the official Claude Code plugin marketplace:

claude plugin install expo@claude-plugins-official

You can also run /plugin install expo@claude-plugins-official inside Claude Code.

Codex Plugin

Install from the OpenAI-curated Codex marketplace:

codex plugin add expo@openai-curated

You can also open /plugins in Codex and install expo from the OpenAI-curated marketplace.

Updating

Claude Code and Codex plugin installs are updated through their official plugin marketplaces.

For skills CLI installs, update installed skills with:

npx skills@latest update

To update a single Expo skill, pass its name:

npx skills@latest update expo-router

Try It

After installing, ask your agent Expo-specific questions like:

• "Build a native-feeling Expo Router screen with tabs, modals, and animations."
• "Create an EAS workflow that builds previews on pull requests."
• "Help me upgrade this app to the latest Expo SDK."
• "Check whether this EAS Update rollout is healthy."

Agents choose the right skill from the task context and each skill's description.

Skills Included

Skills come in two groups so the free vs paid boundary is clear. Each skill's description carries the same label, and every services skill opens with a costs/plan-limits note.

Start Here

Load this first for any Expo/EAS task, then route to the specific skill below.

Framework (open source)

Free, open-source Expo SDK and React Native skills.

Services & paid distribution

Skills whose core purpose uses paid Expo Application Services (EAS).

Experimental

Skills for Expo APIs that are not finalized. Content may change or be retired; skills graduate to the groups above when the underlying API stabilizes. These ship in the separate expo-experiments plugin (install it alongside expo), or individually via the skills CLI.

Expo MCP Server

Skills teach an agent how Expo work gets done. The Expo MCP server gives it live access to actually do that work: read the latest Expo docs on demand, install compatible dependencies with npx expo install, trigger and monitor EAS builds and workflows, pull crash data from TestFlight, and screenshot a running app in the simulator.

The expo plugin bundles this MCP configuration, so Claude Code and Codex plugin installs wire it up automatically. For other agents, or to add it on its own, follow the Expo MCP setup guide.

FAQ

Which AI coding agents are supported?

Use npx skills@latest add expo/skills --skill '*' for Cursor, OpenCode, GitHub Copilot, Windsurf, Gemini, Cline, AMP, Factory Droid, Antigravity, Kiro CLI, and similar AI coding tools.

Should I install the skills or the plugin?

Use the plugin for Claude Code or Codex; it stays updated through the plugin marketplace. Use npx skills@latest add expo/skills --skill '*' for Cursor, OpenCode, and other AI coding agents.

What is the source of truth?

Expo documentation, Expo CLI, and EAS CLI are the source of truth. These skills teach agents how to apply Expo guidance in real projects.

Feedback

Every skill includes instructions to submit specific, actionable feedback with npx --yes @expo/agent-cli@latest feedback.
