Use this skill when working on any backend API code including endpoints, routes, controllers, request handlers, response formatters, authentication mechanisms, API middleware, versioning strategies, or API documentation. Use when creating new API features, refactoring existing API code, implementing REST resources, designing API architecture, setting up API configuration, or working with any files in API-related directories (routes/, controllers/, api/, handlers/, middleware/). Use when working with Express.js, NestJS, FastAPI, Django REST Framework, Rails API, Spring Boot REST, or any other backend API framework.
