clerk-setup: a Claude Code skill by Clerk
Official
For developers adding Clerk sign-in to a web or mobile app through the Clerk CLI. Skip it if you want auth that runs only on your own servers.
Before you install: By default clerk init also installs Clerk's agent skills globally, and every command uses npx -y clerk@latest, which runs the newest CLI release without a prompt.

What does clerk-setup do?
clerk-setup is a Claude skill that adds Clerk authentication with npx clerk@latest init. It first shows you a three-step plan and waits for a yes. It looks for an existing auth provider and stops for an approved migration plan if one is found. On supported frameworks, init works without an account and writes temporary development keys you can claim later. Claude then adds sign-in, sign-up and user buttons to your layout, runs clerk doctor, and applies framework rules such as wrapping Next.js auth UI in <Suspense>. Later steps cover claiming the app, production keys with clerk deploy, host env setup on Vercel, and turning on Organizations.
When should you use clerk-setup?
Use it when
- You are adding login to a new Next.js or React app

Skip it when
- You want self-hosted auth only
- Your app already has a working Clerk setup
What it needs and what it can touch
You need
- Node.js 20.9 or later
- A Clerk account for production (development keys work without one)
What it can do
- Runs shell commands (npx clerk)
- Reads and edits project files
- Installs Clerk's agent skills globally unless skipped
