ユースケースの詳細化スキル。漠然とした要求メモから作成されたユースケースを、API設計に十分な詳細レベルに引き上げる。CRUD操作の補完、エラーケースの定義、検証ルールの抽出を行う。Use when: (1) ユースケースが抽象的で検索条件・エラーケース・バリデーションが未定義, (2) データモデリング前にAPI設計の詳細を明確化したい, (3) Phase 0完了後にPhase 0.5として実行, (4) `/usecase-detailer` コマンドで明示的に実行
Validating external data from APIs, JSON parsing, user input, and any untrusted sources in TypeScript applications
Use when creating or modifying API endpoints. Provides REST conventions and error handling patterns for this project.
Design and implement RESTful API endpoints following REST principles with proper HTTP methods, status codes, and URL conventions. Use this skill when creating or modifying API routes, route handlers, API endpoint files, controller files that handle HTTP requests and responses, or any server-side files that define RESTful endpoints. Use this when working on API versioning, implementing rate limiting, designing resource-based URLs, handling query parameters for filtering/sorting/pagination, or structuring nested resource endpoints. Use this when writing code in files like routes.js, api.js, controllers/, handlers/, endpoints/, or any file that defines HTTP API routes and responses.
Generate JSON API endpoints with authentication and versioning. Use when user needs API, mobile backend, external integration, or says "create API", "add endpoint", "JSON response", "API for mobile", "REST API".
To be used for writing API endpoints with Express.js. Follow these instructions to implement RESTful API endpoints.
Usa este skill cuando el usuario pida crear o modificar DTOs (Data Transfer Objects) que se comparten entre backend y frontend.
Implement complete CRUD (Create, Read, Update, Delete) operations for Supabase tables with proper error handling, validation, and RLS. Triggers when user requests data operations, API endpoints, or database interactions.
Use Zod to validate and type inputs at boundaries (route params/search params, server functions, DB access). Use when adding validation or debugging input issues.
FastAPI backend patterns for Pricing App - SQLAlchemy, Alembic, auth, permissions
Generator สำหรับสร้าง API endpoint พร้อม controller, service, repository, validation, tests และ documentation โดยอัตโนมัติ
Standard patterns for building and maintaining CRUD APIs with FastAPI and SQLModel: models, routers, database access, and error handling in a reusable way.
API client code generation workflow. Use when modifying backend routes, response schemas, or request models. Automatically regenerates TypeScript API client from OpenAPI schema.
Use Prisma's generated types, `Prisma.validator`, and `GetPayload` for type-safe queries.
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。
REST API design standards for FanHub's Express backend. Use when creating or modifying API endpoints to ensure consistency.
Comprehensive FastAPI development guide for building production-grade REST APIs. This skill should be used when building FastAPI applications from hello world to production-ready APIs, implementing CRUD operations, handling exceptions, configuring CORS, rate limiting, authentication, file uploads, and API design patterns.
Design and implement RESTful API endpoints following REST principles with clear resource-based URLs and appropriate HTTP methods. Use this skill when creating API routes, defining API endpoints, implementing HTTP request handlers, working on route files (routes.ts, route.ts, api/*, controllers/*, handlers/*), building REST APIs, designing API versioning strategies, setting up query parameters for filtering and pagination, implementing rate limiting, or returning appropriate HTTP status codes. Apply this skill when structuring backend API architecture, creating new API endpoints, refactoring existing endpoints, or reviewing API design for consistency and best practices.
WHEN: Go API review with Gin/Echo/Fiber/Chi, router patterns, middleware, request handling WHAT: Router organization + Middleware patterns + Request validation + Error responses + OpenAPI WHEN NOT: General Go → go-reviewer, Rust API → rust-api-reviewer
A skill for implementing robust API request validation in Python web frameworks like FastAPI using Pydantic. Covers Pydantic models, custom validators (email, password), field-level and cross-field validation, query/file validation, and structured error responses. Use when you need to validate incoming API requests.
Design API endpoints, schemas, and contracts. Use when defining public interfaces or data models.
Design and implement RESTful API endpoints following REST principles with consistent naming conventions, proper HTTP methods, versioning strategies, and appropriate status codes. Use this skill when creating new API endpoints, designing API route structures, implementing API controllers or routes, defining API versioning strategies, setting up API rate limiting, or working with query parameters for filtering, sorting, and pagination. This skill applies when working on routes/api.php files, API controller files, API resource transformers, or any backend code that exposes HTTP API endpoints to clients.
Hono + Zod で型安全な CRUD API を構築し、クライアント通信とテストを統合します。API実装、リクエスト検証、RPC通信、ローカルテストが必要な場合に使用します。
Design and implement RESTful API endpoints following REST principles with proper HTTP methods, status codes, and resource-based URLs. Use this skill when creating or modifying API endpoints, route handlers, controllers, or API configuration files. Apply when working on REST API design, endpoint implementations, API versioning, request/response handling, HTTP method routing (GET, POST, PUT, PATCH, DELETE), query parameter filtering, API rate limiting, or any file that defines API routes such as routes.py, api.js, controllers/, endpoints/, or API documentation files.
