Backend API Standards

What problem does it solve?

This Skill addresses the challenges of inconsistent, poorly designed API endpoints that are hard to use, maintain, and scale. It helps prevent integration headaches, security risks, and ensures a predictable, developer-friendly API surface.

Core Features & Use Cases

• RESTful Design Principles: Enforces resource-based URLs, appropriate HTTP methods (GET, POST, PUT, PATCH, DELETE), and consistent naming conventions for intuitive API design.
• Accurate Status Codes & Responses: Guides on returning correct HTTP status codes (e.g., 200 OK, 201 Created, 400 Bad Request) and structured response/error formats for clear communication.
• Versioning & Query Parameters: Provides strategies for API versioning (e.g., /v1/users) and effective use of query parameters for filtering, sorting, and pagination.
• Use Case: When creating a new /products API endpoint, use this skill to ensure it follows REST principles (e.g., GET /products, POST /products), uses correct HTTP status codes, and supports filtering by category via query parameters.

Quick Start

Apply the Backend API Standards skill to design a new API endpoint for 'orders', ensuring it uses plural nouns, appropriate HTTP methods for CRUD operations, and returns 201 Created for successful POST requests.
