Designing Apis

What it does

This skill enables AI agents to generate complete API specifications, including OpenAPI schemas and endpoint definitions. It automates the creation of structured documentation for RESTful services based on high-level requirements or functional descriptions.

When to use it

• You need to rapidly prototype an API before writing backend code.
• Your team requires consistent, machine-readable documentation (OpenAPI/Swagger) for frontend developers.
• You are building a microservice architecture and need to define contracts between services early in the development cycle.

Key capabilities

• Generates OpenAPI 3.x specification documents from natural language prompts.
• Defines endpoint paths, HTTP methods, request/response schemas, and status codes.
• Creates detailed API documentation including parameter descriptions and error handling strategies.

Example prompts

• "Create an OpenAPI spec for a user authentication service with endpoints for login, registration, and password reset."
• "Design a REST API schema for an e-commerce product catalog that supports filtering by category and price range."
• "Generate full API documentation including request/response JSON examples for a weather data retrieval endpoint."

Tips & gotchas

Ensure your prompts include specific details about data types, authentication methods (e.g., OAuth2, API keys), and error codes to get production-ready specs. While the skill generates comprehensive schemas, always review generated code against security best practices before deployment.
