Auth0 Agent Skills

📚 Documentation • 🚀 Getting Started • 💬 Feedback

AI agent skills for Auth0 authentication integration. These skills help AI coding assistants (Claude Code, Cursor, Copilot) implement Auth0 correctly across any framework.

What are Agent Skills?

Agent Skills are structured instructions that help AI agents implement features correctly. Each skill contains best practices, code patterns, and step-by-step guidance for Auth0 integration.

Learn more at agentskills.io and skills.sh

Quick Start

Get Auth0 up running in your app in minutes:

Prerequisites

An Auth0 account (sign up free)
An AI coding assistant (Claude Code, Cursor, or GitHub Copilot)

Steps

Install the Auth0 skills (choose one method):
Option 1: Via Skills CLI (fastest)

npx skills add auth0/agent-skills

Option 2: Via Claude Code marketplace

# Open Claude Code
claude

# Add the Auth0 marketplace
/plugin marketplace add auth0/agent-skills

# Install the plugin
/plugin install auth0@auth0-agent-skills

Ask your AI assistant to add Auth0:

 "Add authentication to my React app"
 "Implement login with Auth0"
 "Add MFA to my application"

That's it! Your AI assistant will setup Auth0 on your app and you will have production-ready authentication powered by Auth0.

Installation

Option 1: Claude Code Marketplace (Recommended for Enterprise)

Step 1: Open Claude Code

claude

Step 2: Add the Auth0 Marketplace

Add the Auth0 agent skills marketplace to Claude Code:

# From GitHub
/plugin marketplace add auth0/agent-skills

# Or from local path
