Is it compatible with NestJS?

Yes, it includes specific validation and best-practice patterns for implementing Clerk Guards within NestJS applications.

Why does this skill prefer proxy.ts over middleware.ts?

Next.js 16 introduces new patterns for edge middleware; this skill ensures you are using the optimized clerkMiddleware pattern required for the latest framework versions.

Does it check for environment variable values?

It verifies that the necessary keys (like CLERK_SECRET_KEY) are present and follow the correct naming conventions, but it does not store or transmit your actual secrets.

Can I use this with Cursor or other AI editors?

Yes. While optimized for Claude Code, the underlying validation script can be run in any terminal to audit code generated by Cursor, Codex, or ChatGPT.

Security & Testing

Validates Clerk authentication configurations and enforces modern implementation patterns for Next.js and NestJS applications.

The Clerk Validator skill ensures your authentication setup follows the latest security standards and architectural patterns, specifically targeting the transition to Next.js 16 and modern Clerk SDKs. It automatically detects deprecated patterns like authMiddleware or outdated import paths that AI assistants often hallucinate, replacing them with current best practices like clerkMiddleware and proxy.ts. Use this skill to audit existing configurations, validate new implementations during development, or integrate it into CI/CD pipelines to prevent technical debt and security regressions.

Key Features

01Package version auditing to ensure compatibility with modern SDKs
