This skill provides comprehensive guidelines based on Clean Code principles, transforming merely functional code into highly readable, maintainable, and robust software. It covers best practices for naming conventions, function design (small, single responsibility), error handling (exceptions over return codes), formatting, and adhering to Test-Driven Development (TDD). Use this skill when writing new features, reviewing pull requests, or refactoring legacy systems to improve overall code quality.

This guide provides expert architectural patterns for implementing robust authentication using Clerk in Next.js 14/15 App Router. It covers essential setups like ClerkProvider, middleware route protection (including role/permission checks), and accessing user data in Server Components and Server Actions. Ideal for building secure, scalable, and enterprise-grade web applications.

A comprehensive guide for diagnosing and resolving common configuration, authentication, and runtime errors when integrating the Clerk authentication SDK. Covers issues like missing environment variables, middleware setup, session mismatches, and component usage in Next.js environments.

Learn how to implement robust authentication and authorization flows using Clerk in Next.js. This guide covers configuring `clerkMiddleware` for route protection, protecting API endpoints with permission checks, customizing session claims (JWT), and generating secure tokens for external services like Supabase. Essential for building secure, enterprise-grade SaaS applications.

This utility collects comprehensive debug information for troubleshooting complex issues related to Clerk authentication. It generates an environment report, runtime health checks, client-side debug panel data, and middleware logs. Use this tool when preparing detailed support tickets or diagnosing intermittent, hard-to-reproduce bugs.

This comprehensive guide demonstrates how to implement enterprise-grade Role-Based Access Control (RBAC) and organization management using Clerk. It covers setting up multi-tenant architectures, defining granular custom roles and permissions (e.g., data:write, org:admin), integrating SSO (SAML/OIDC), and securely protecting both Next.js routes (via middleware) and client components based on user roles and specific permissions. Ideal for building secure, scalable SaaS applications.

This guide provides a comprehensive walkthrough for installing and configuring the Clerk SDK for various frameworks (Next.js, React, Express). It covers setting up environment variables, implementing the ClerkProvider, configuring middleware for route protection, and setting up sign-in/sign-up pages. Use this skill when integrating Clerk for secure, managed user authentication into a new application.

Implement comprehensive monitoring, structured logging, and performance tracking for Clerk authentication flows. This solution covers logging sign-in/out events, tracking middleware performance, handling webhook events, and integrating detailed error tracking with Sentry, ensuring robust debugging and auditing capabilities in production environments.

A comprehensive guide to enhancing Clerk authentication performance within a Next.js application. Techniques covered include optimizing middleware routing, implementing React's cache() and unstable_cache() for data deduplication, optimizing token handling, utilizing dynamic imports for lazy loading, and leveraging Edge Runtime for faster cold starts. Ideal for reducing latency and improving user experience during authentication flows.

This comprehensive guide outlines essential patterns and best practices for integrating the Clerk SDK into modern applications. It covers crucial components like server-side and client-side authentication flows, protecting routes with middleware, implementing organization-aware data queries, and generating custom JWT tokens for secure third-party integrations. Ideal for developers building robust, secure, and scalable applications.

This comprehensive guide outlines essential, production-grade security best practices for implementing Clerk authentication. It covers securing environment variables, hardening middleware with crucial security headers (like CSP, X-Frame-Options), protecting API routes with granular authorization checks, and verifying webhooks using signature validation (svix). Use this when deploying or auditing an application to ensure maximum security posture.

Provides a comprehensive, step-by-step guide and scripts for safely upgrading Clerk SDK packages. This tool helps developers manage version upgrades and critical breaking changes (e.g., async auth calls, middleware renaming, import path changes), ensuring a smooth and reliable transition to the latest SDK version.
