Skill UI

This comprehensive guide covers universal coding standards, best practices, and architectural patterns for modern web development using TypeScript, JavaScript, React, and Node.js. It emphasizes fundamental principles like Readability, DRY, and Immutability, while providing detailed guidelines on component structure, state management, asynchronous programming, and designing robust REST APIs.

This skill provides a comprehensive checklist for performing rigorous code security reviews. It covers critical areas such as secrets management, input validation, preventing SQL injection, secure authentication (JWT, RLS), and mitigating XSS/CSRF vulnerabilities. Essential for developers building features that handle sensitive data or user input.

This comprehensive skill guide details the implementation of robust and secure API authentication systems. It covers industry standards like JWT, OAuth 2.0 (including various flows), and API key management. Key features include role-based access control (RBAC), refresh token rotation, session management, and brute-force protection, ensuring secure communication for diverse service architectures.

This skill details the architecture and implementation of a robust API Gateway, serving as the single entry point for multiple backend microservices. It centrally manages critical cross-cutting concerns, including path-based and header-based routing, JWT/OAuth2 authentication, rate limiting, load balancing, and circuit breaker protection. This pattern is essential for building resilient, scalable, and maintainable microservices architectures, significantly simplifying client integration and request management.

This comprehensive guide details how to utilize the Bun runtime for modern, high-performance JavaScript and TypeScript development. It covers everything from initial setup and project scaffolding to advanced package management, running code, and leveraging built-in APIs like file system operations. It is designed for developers migrating from Node.js seeking superior speed and native tooling.

This comprehensive guide provides solutions for the most frequent errors encountered when using Clay for data enrichment, webhooks, and API integrations. It covers issues such as 422/404 webhooks, credit limits, data quality failures, and rate limiting, ensuring smooth data workflow management.

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.

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.

Comprehensive guide for configuring Bring Your Own Key (BYOK) for major AI providers, including OpenAI, Anthropic, Google Gemini, Azure, and custom endpoints. This allows users to bypass default quotas, manage costs directly with the source provider, and utilize a wide range of specialized models within the Cursor IDE. It covers setup steps, security best practices, and cost monitoring strategies.

A powerful AI tool designed for complex, coordinated programming tasks. It enables developers to generate, refactor, and scaffold entire features across multiple files (e.g., schema, API routes, service layers, tests) while maintaining consistency with existing codebase patterns. It supports agent mode for autonomous, multi-step changes and allows systematic migration and review of all affected files via detailed diffs.

A comprehensive toolkit for advanced debugging and systematic incident response within Customer.io. It provides structured playbooks, API debug clients, and investigation scripts to diagnose complex delivery issues, analyze user profiles, or troubleshoot campaign failures, ensuring robust incident management.

This skill implements core Customer.io platform features, enabling sophisticated customer communication workflows. Key functionalities include sending transactional messages (e.g., receipts, password resets) and push notifications, executing API-triggered broadcasts to defined segments, and managing user attributes to dynamically drive segment membership. Ideal for building advanced, data-driven marketing automation and customer lifecycle management systems.
