Q: How do I add Clerk authentication with an AI agent?

Paste Add Clerk auth to my agent: clerk.com/SKILL.md into your agent and it reads Clerk’s instructions and implements auth for you. You can also follow the step-by-step guide for your specific tool.

Question 1

How does Clerk work with agents?

Accepted Answer

Clerk lets an agent add complete authentication to your app for you. Point your agent at clerk.com/SKILL.md and it installs the Clerk SDK, adds the provider, and wires up sign-in, sign-up, and user management using Clerk’s prebuilt components.

Question 2

Which agents and tools does Clerk support?

Accepted Answer

Clerk provides tailored setup guides for Claude Code, Cursor, Codex, VS Code, Zed, and Devin. Because the instructions live at a plain URL (clerk.com/SKILL.md), any agent that can read a URL can use them.

Question 3

How do I add Clerk authentication with an AI agent?

Accepted Answer

Paste Add Clerk auth to my agent: clerk.com/SKILL.md into your agent and it reads Clerk’s instructions and implements auth for you. You can also follow the step-by-step guide for your specific tool.

Question 4

Do I have to write the authentication code myself?

Accepted Answer

No. Your agent handles the integration end to end — installing the SDK, adding the provider, and dropping in Clerk’s prebuilt components — so you review a working setup instead of writing it from scratch.

Question 5

Which frameworks can an AI agent set up Clerk in?

Accepted Answer

The agent auto-detects your framework and follows the matching Clerk quickstart — including Next.js, React, Remix, Astro, Nuxt, React Router, TanStack Start, Vue, Express, Fastify, and Expo, plus guides for Chrome Extension, Android, iOS, and vanilla JavaScript.
