clerk_skill

Overview

This skill is a Clerk authentication router that directs requests to the exact Clerk-focused helper you need. It maps common tasks—setup, custom UI, Next.js patterns, organizations, webhooks, and testing—to specialized subskills. Use it when you want fast, targeted guidance for any Clerk-related workflow.

How this skill works

You describe the task or choose from common categories and the router selects the best subskill for that job. Each subskill contains concrete instructions, code patterns, and configuration steps for its target area. When applicable the router provides direct links or shortcuts to the specific subskill endpoint so you can jump straight to the focused guidance.

When to use it

• Adding Clerk to a new or existing project
• Creating custom sign-in/sign-up flows or styling Clerk UI
• Implementing advanced authentication patterns in Next.js
• Building multi-tenant apps, organizations, roles, and RBAC
• Handling real-time events via webhooks and data syncing
• Setting up end-to-end tests for auth flows with Playwright or Cypress

Best practices

• Describe your exact goal (framework, hosting, and whether you’re migrating) so the router picks the right subskill
• Use the setup subskill for environment and API key steps before customizing UI or middleware
• Follow Next.js pattern recommendations for server vs client auth to avoid token exposure
• For organizations and RBAC, plan slugs and permission models early to minimize migration work
• Add webhooks and testing config to CI so auth changes are validated automatically

Example use cases

• I need a Next.js quickstart with Clerk and server-side session handling — route to Next.js patterns
• I want a custom sign-in flow with passkeys and magic links — route to custom UI guidance
• Migrating from another auth provider to Clerk and preserving user data — route to setup and migration steps
• Set up organization roles, member invites, and per-organization subdomains — route to orgs guidance
• Write Playwright tests that authenticate programmatically for CI — route to testing utilities
