LABSCO SUMMARY
Auth0's agent-skills repository now holds one skill, auth0, which helps your coding assistant add Auth0 sign-in to an app, from a login page to a protected API or multi-factor sign-in.
The skill reads your project files, such as package.json or requirements.txt, works out the framework and loads Auth0's guide for it; the list runs from React, Next.js and Express to Spring Boot, Android, iOS and Flutter, and it also covers moving users over from Firebase, Cognito, Supabase or Clerk. It replaced the one-skill-per-framework set of earlier versions: names such as auth0-react or auth0-nextjs no longer exist, so any instruction that mentions them should say auth0 instead.
It installs as a plugin in Claude Code, from Anthropic's official plugin marketplace, and in Cursor, and into GitHub Copilot and other assistants with the Skills CLI. Real work needs an Auth0 account (the free tier works) and your app's domain and client ID from the Auth0 Dashboard; for changes inside the account it uses the Auth0 command-line tool by default.
WHAT'S INSIDE
Auth0's own skill for adding sign-in to an app with your coding assistant. Say what you need, such as a login page, a protected API, multi-factor sign-in or a move from Firebase or Cognito; it reads your project, works out the framework and follows Auth0's guide for that setup.
Add Auth0 authentication to any app — login, MFA, SSO, Organizations, RBAC, ACUL, custom domains, and branding. Debug auth errors, validate JWTs, manage token lifecycles, and migrate from Clerk, Firebase, or Cognito.
INSTALL
SINGLE SKILL
Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

/plugin marketplace update claude-plugins-official/plugin install auth0@claude-plugins-officialTyped inside Claude Code, not in a terminal. If it says not found, first run /plugin marketplace add anthropics/claude-plugins-official. As of 8 October 2026 this installs version 2.2.0. The skills CLI takes Auth0's latest: 2.4.0 on that date. 2.4.0 adds passkey sign-in and TanStack Start guides.
SKILLS CLI
npx skills add auth0/agent-skills --allRun in a terminal; needs Node.js. Adds the skill to every assistant the tool supports. For some only, swap --all for --agent plus their names. Example: --agent claude-code cursor.
