Create rich, responsive interactive experiences that make applications a joy to use. Use this skill when building components with user interactions, forms, data-heavy interfaces, or any feature requiring thoughtful UX patterns. Complements frontend-design with psychology-driven interaction patterns.

This skill should be used when the user asks to "write a spec", "create a specification", "define acceptance criteria", "break down a feature", "write user stories", or needs guidance on structuring feature requirements. Provides patterns for effective spec writing and task decomposition.

Design and implement RESTful API endpoints following best practices for URL structure, HTTP methods, status codes, and versioning. Use this skill when creating or modifying API routes, controllers, or endpoint handlers. When working on files like routes.py, api.py, controllers/, endpoints/, or any file defining HTTP endpoints. When designing URL patterns, choosing HTTP methods (GET, POST, PUT, PATCH, DELETE), implementing pagination, filtering, or sorting. When adding rate limiting headers or API versioning strategies.

A comprehensive pattern for handling asynchronous operations in JavaScript/TypeScript applications with automatic cleanup, graceful error handling, and memory leak prevention.
