Implement Clerk Authentication Safely
Clerk setup can be error-prone across middleware, server components, organizations, and webhooks. This skill provides focused implementation guidance for secure Next.js authentication flows.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "clerk-auth" from https://skillstore.io/skills/sickn33-clerk-auth.md and its manifest at https://skillstore.io/api/skills/sickn33-clerk-auth/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "clerk-auth". I need Clerk auth for a new Next.js dashboard.
Expected outcome:
A setup checklist covering provider placement, environment variables, sign-in routes, sign-up routes, user menu placement, and protected dashboard routes.
Using "clerk-auth". My dashboard routes should require a signed-in user.
Expected outcome:
A middleware plan that separates public pages from private route groups and applies explicit protection to dashboard areas.
Using "clerk-auth". I need to use organization membership in server components.
Expected outcome:
Guidance on reading authenticated user context, checking organization identifiers, and keeping authorization checks on the server.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Add Clerk to a New Next.js App
Plan provider setup, sign-in pages, sign-up pages, and user menu placement for a new application.
Protect Application Routes
Design middleware rules for public pages, private dashboards, and route groups that require active sessions.
Review Auth Integration Choices
Check whether server components, session claims, organizations, and user sync flows are being used consistently.
Try These Prompts
Help me add Clerk authentication to a Next.js App Router project. Include provider placement, sign-in pages, sign-up pages, and required environment variables.
Design Clerk middleware rules for my Next.js app. Public routes are home, pricing, and docs. Protected routes are dashboard, settings, and billing.
Show how to use Clerk auth state in server components. Explain when to use auth(), currentUser(), userId, sessionId, orgId, and claims.
Review this Clerk authentication plan for risks and missing pieces. Cover middleware, organizations, webhooks, user sync, and server-side authorization.
Best Practices
- Keep all route protection rules centralized in one middleware file.
- Use server-side authorization checks for sensitive data access.
- Verify Clerk API behavior against current official documentation.
Avoid
- Relying only on client UI state to protect private data.
- Scattering authentication checks across unrelated files without a clear policy.
- Assuming organization membership equals permission for every protected action.
