Skill UI

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.

This comprehensive guide details how to configure robust CI/CD pipelines for applications secured by Clerk authentication. It covers setting up GitHub Actions workflows, utilizing Playwright for end-to-end (E2E) testing, managing test user states, and scripting user seeding for reliable automated testing environments. Essential for developers integrating Clerk into their build and deployment process.

A comprehensive guide to implementing robust user authentication flows using Clerk. Learn to set up sign-up and sign-in pages, integrate OAuth social logins (Google, GitHub, Apple), and customize the UI entirely. This guide covers both quick pre-built component usage and advanced custom form implementation with full error handling and MFA support, ideal for building modern SaaS applications.

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 guide provides comprehensive strategies to optimize costs associated with Clerk authentication services. It details understanding the MAU pricing model, implementing route-level authentication controls, utilizing caching techniques to reduce API calls, and scripting the cleanup of inactive users, helping maintain compliance and controlling expenditure.

This skill provides comprehensive methods for managing user data and ensuring compliance with global privacy regulations like GDPR and CCPA. It covers essential features such as data export, implementing the "right to be forgotten" (user deletion), managing user consent via metadata, and maintaining detailed audit logs. Use this for building robust, legally compliant user data management systems in modern web 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.

A comprehensive guide for deploying applications authenticated with Clerk to various major hosting platforms, including Vercel, Netlify, Railway, and custom Docker setups. It details environment variable setup, domain configuration, webhook handling, and provides post-deployment verification scripts to ensure a robust production environment.

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.

A comprehensive guide for engineering teams to manage critical incidents related to Clerk authentication and SaaS platform outages. It covers full incident lifecycle procedures, including initial triage, emergency auth bypass implementation, key rotation, session recovery scripts, and post-incident root cause analysis. Use this when facing production authentication failures or security breaches.

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.
