API Docs

Keep the backend REST API and the shared OpenAPI spec in sync. Use when adding/changing endpoints so the contract in the shared repo stays accurate.

Automatically generate and execute Python test scripts from OpenAPI specifications

Comprehensive FastAPI best practices, patterns, and conventions for building production-ready Python web APIs. Covers application structure, async patterns, Pydantic models, dependency injection, database integration, authentication, error handling, testing, OpenAPI documentation, performance optimization, and common anti-patterns. Essential reference for FastAPI code reviews and development.

REST/GraphQL APIの設計と OpenAPI 仕様の作成を支援します。エンドポイント設計、エラー処理、セキュリティ対策を含む包括的なAPI仕様を提供します。新規API設計、API仕様の標準化、インターフェース設計が必要な場合に使用してください。

Guide for contributing to the OpenAPI layer using processor pattern, complexity management, and functional programming. Use when adding endpoint factories, processors, parameter descriptions, reducing cyclomatic complexity, or fixing OpenAPI validation errors. Covers architecture patterns from user-service repository.

Import, export, and manage Postman collections. Use when working with Postman collections, importing OpenAPI specs, exporting collections, or when user mentions Postman import, collection management, API collections.

Design and implement RESTful APIs, GraphQL endpoints, and backend API architecture following modern standards. Use this skill when creating or modifying API endpoints, route handlers, controllers, API middleware, authentication/authorization logic, or any files that define HTTP endpoints such as routes.py, api.js, controllers/, endpoints/, or API specification files (OpenAPI/Swagger). Apply this skill when implementing API versioning, rate limiting, request/response handling, API documentation, or when working with API gateway configurations. This skill is essential for building scalable, secure, and well-documented APIs that follow RESTful principles, handle errors gracefully, and provide consistent developer experiences across microservices and serverless architectures.

ReactでSPAフロントエンドを実装・改修するためのガイド。バックエンド分離前提でNext.jsやサーバーサイド機能に依存せず、React Router中心のクライアント実装を行う時に使う。認証はAuthProviderとuseAuthカスタムフックで統一し、OpenAPIからorvalまたはopenapi-typescriptで型/クライアントを生成して利用する。ESLint+Prettier、zod、shadcn/ui、デザイントークン（CSS変数/Tailwindテーマ）を前提にする場合に適用する。ディレクトリ構成はmodules/components/hooks/providers/servicesなどの直感的な命名で複雑化に耐える構成にする。

Design and implement RESTful API endpoints following industry best practices for resource naming, HTTP methods, status codes, and versioning. Use this skill when creating or modifying API route handlers, endpoint files, controller files, or API router configuration files. Use this skill when working with REST API design, implementing HTTP endpoints in backend frameworks, defining API routes and URL patterns, setting up API versioning strategies, or configuring request/response handling in web services. Use this skill when working with files in routes/, api/, controllers/, endpoints/, or views/ directories that handle HTTP requests. Use this skill when defining OpenAPI/Swagger specifications, implementing rate limiting, or establishing API conventions for your application.

Run and analyze Newman (Postman CLI) tests. Use when running API tests, validating Postman collections, testing HTTP endpoints, or when user mentions Newman, Postman tests, API validation.

Rust/WASM backend in api-rust/. High-performance alternative using workers-rs, utoipa for OpenAPI, and Supabase REST API. Port 9999 for local dev. 10-100x faster than Python.

Provides API design patterns for Rust backends including request validation with validator, OpenAPI documentation with utoipa, and SwaggerUI integration. Use when building REST APIs with Axum, adding request validation, generating OpenAPI specs, or setting up API documentation.

Keep web expectations and the shared OpenAPI spec in sync. Use when frontend work implies new/changed backend endpoints so the contract in the shared repo stays accurate.

Expert API development including REST, GraphQL, OpenAPI, versioning, and documentation

Generates protobuf API definitions for go-kratos microservices with HTTP annotations, validation rules, and OpenAPI documentation. Use when defining service contracts and APIs.

Generate type-safe API clients from OpenAPI/Swagger specifications or API documentation. Use when users need to create TypeScript or Python API clients with Zod/Pydantic validation, retry logic, error handling, and proper typing. Supports REST APIs, generates from OpenAPI specs or manual endpoint definitions.

OpenAPI diff tools, schema comparison, and migration guide templates for detecting breaking changes in APIs, databases, and contracts. Use when analyzing API changes, comparing OpenAPI specs, detecting breaking changes, validating backward compatibility, creating migration guides, analyzing database schema changes, or when user mentions breaking changes, API diff, schema comparison, migration guide, backward compatibility, contract validation, or API versioning.

Zod v4 schema patterns with .meta() for OpenAPI, transforms, refinements, and custom serializers. Triggers on zod, z.object, z.string, schema, validator.
