Skill UI

A specialized skill for writing highly efficient, memory-safe, and robust C code. This guide focuses on best practices for systems programming, including rigorous memory management (malloc/free), advanced pointer arithmetic, POSIX compliance, multi-threading (pthreads), and embedded systems constraints. It emphasizes using static analysis tools, implementing comprehensive error handling, and ensuring performance through proper profiling. Ideal for complex, low-level system tasks.

This guide provides comprehensive patterns and best practices for writing robust unit tests for shell scripts using Bats (Bash Automated Testing System). It is ideal for developers implementing Test-Driven Development (TDD) for shell utilities, setting up robust automated testing in CI/CD pipelines, and validating edge cases and error conditions in shell environments.

Build, modify, debug, migrate, review, or verify TypeScript MCP servers and MCP Apps with mcp-use. Covers tools, resources, prompts, middleware, Views, authentication, Skills over MCP, scaffolding, and advanced features.

Audits and improves CLAUDE.md files across repositories by discovering every relevant file, scoring its sections, reporting quality issues, and preparing targeted additions before any write actions.

This skill provides comprehensive strategies for managing API rate limits and webhooks within the Clay platform. It addresses webhook throttling, plan-level rate limits (hourly/per-second), and webhook submission exhaustion (50K limit). Use this when integrating with Clay to ensure reliable, optimized data throughput and handle 429 errors gracefully with backoff strategies.

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.
