Skill UI

This comprehensive workflow guides the process of building and deploying new features that must maintain consistent functionality and design across multiple operating systems (web, mobile, and desktop). It strictly follows an API-first architecture, starting with defining shared API contracts (OpenAPI/GraphQL) and a unified design system. The process then guides parallel implementation across specialized stacks like React/Next.js, SwiftUI, and Jetpack Compose, ensuring high code consistency and faster time-to-market.

This skill provides comprehensive patterns for creating, maintaining, and validating OpenAPI 3.1 specifications for RESTful APIs. Use it for design-first API contract definition, generating specs from existing code, creating detailed API documentation, validating implementation conformance against the contract, and generating client SDKs. It ensures consistency across the entire API lifecycle.

Automates OpenAPI specification work by guiding API developers through best practices, generating production-ready code/configs, and validating outputs for REST, GraphQL, and authentication design patterns.

Guides API development teams through pagination helper tasks by providing best-practice guidance, ready-to-run code, and validation for REST, GraphQL, OpenAPI, and related authentication/design workflows.

Guides API developers through building request body validators, following best practices for REST, GraphQL, and OpenAPI workflows, and generating production-ready code plus validations.

Guides API developers through automatic response schema generation, offering best practices, code/configuration samples, and validation to keep REST, GraphQL, or OpenAPI responses compliant.

Rest Endpoint Designer automatically activates when you ask about designing REST APIs, providing best-practice guidance, sample configurations, OpenAPI/GraphQL tips, and validation checks so your API development stays production-ready.

A comprehensive toolset for the full backend development lifecycle. This suite enables developers to scaffold API routes from OpenAPI specifications, manage complex database migrations and optimization (PostgreSQL), and perform rigorous load/performance testing. It supports building robust microservices, securing REST APIs, and ensuring system scalability.

Automates guidance for sorting parameter handlers in API development, covering REST, GraphQL, OpenAPI, authentication, and design patterns, with step-by-step best practices and production-ready validation.

Assists API developers by recommending appropriate status codes, explaining patterns, and generating production-ready REST/GraphQL/OpenAPI snippets with validations.

Automates swagger documentation tasks by offering best-practice guidance, example code, and validation when working on REST, GraphQL, or OpenAPI-based API development requests.

Validates API contracts using Pact and OpenAPI, generating consumer-driven contract tests, verifying responses, and ensuring backward compatibility for CI/CD workflows.
