Skills follow the Agent Skills format.
Install
The clerk plugin bundles every skill plus the Clerk MCP server. npx skills installs the skills alone, into any agent.
Agent Skills
npx skills add clerk/skills
Claude Code
/plugin marketplace add clerk/skills
/plugin install clerk@clerk-skills
To get updates automatically, open /plugin, go to Marketplaces, select clerk-skills, and enable auto-update.
Codex
codex plugin marketplace add clerk/skills
codex plugin add clerk@clerk
clerk replaces the earlier clerk-skills@clerk plugin, which no longer updates. To switch, run codex plugin remove clerk-skills@clerk, then add clerk@clerk.
Cursor
cursor-agent plugin marketplace add https://github.com/clerk/skills
Then install clerk from /plugin, or from Customize in the editor.
GitHub Copilot CLI
copilot plugin marketplace add clerk/skills
copilot plugin install clerk@clerk-skills
clerk replaces the earlier core, frameworks, features, and mobile plugins. Copilot moves those installs to clerk@clerk-skills but leaves it disabled, so run copilot plugin enable clerk@clerk-skills once.

Quick Start
1. Ask Your Agent to Add Clerk
After installing Clerk Skills, ask your coding agent to add Clerk authentication
to your app. The clerk-setup skill sets up
Clerk in an existing project, scaffolds a new app in an empty directory, and can
link an existing Clerk application instead of creating a new one.
For a new project on a supported framework, clerk init can start without a
Clerk account or browser login. See Accountless development keys
for how temporary keys and later account claiming work.
