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.
Implement Create, Read, Update, Delete operations for todo tasks. Use when building data management functionality.
Fetch API patterns with error handling, retry logic, and caching. Use when building API integrations, handling network failures, or implementing offline-first data fetching.
Design and implement RESTful API endpoints with proper HTTP methods, status codes, and consistent naming conventions. Use this skill when creating or modifying API routes, endpoints, or server-side request handlers. When working on files in src/pages/api/, files containing API route definitions, files implementing REST endpoints, files handling HTTP requests and responses, server middleware for API requests, API authentication and authorization logic, and files defining API versioning strategies. When designing URL structures for resources, implementing query parameter handling for filtering/sorting/pagination, setting up rate limiting for API endpoints, or configuring CORS and API security headers.
Type-safe schema validation with Zod for runtime data validation, form handling, and API contracts
新しいAPIエンドポイントを追加する際に使用。Huma API、Echo、Handler/Service/Repositoryの3層構成、エンドポイント登録パターンを適用。REST API、新規エンドポイント、CRUD APIを追加する場合に使用。
Automatically applies when creating FastAPI endpoints, routers, and API structures. Enforces best practices for endpoint definitions, dependency injection, error handling, and documentation.
Use when implementing shared connection pool for multiple services in same application - provides complete setup steps for FastAPI/multi-service apps without needing examples
Create front/back Route controllers extending BaseRoute. Use for pages and form endpoints.
Frontend/backend API contract definitions. Use for defining API endpoints, Pydantic to TypeScript mapping, schema validation, error responses, and pagination contracts.
Scaffold new tRPC API endpoints for the dealflow-network project with proper Zod validation, middleware, database functions, and client hooks. Use when adding new API routes, creating CRUD operations, or extending existing routers.
Guide for creating paginated list endpoints with cursor-based pagination and RFC 8288 Link headers following this project's conventions.
Use when building FastAPI applications with SQLModel for database models, CRUD operations, and full-stack data management. Also use for implementing relationships, migrations, async queries, and type-safe database interactions with Pydantic integration. NOT when using other ORMs (SQLAlchemy directly, Tortoise ORM) or building non-FastAPI applications.
Rails serializers - variants for different response shapes, one serializer per resource. Use when working with serializers.
Jakarta EE 10とJAX-RS 3.1を使ったREST APIサービス開発を支援。エンティティ実装、外部API連携など多様な実装要件に対応。SPECからタスク分解、詳細設計、コード生成、単体テスト実行評価、結合テスト、E2Eテストまで7段階で一貫サポート。基本設計変更対応も含む。
Development guidelines for Quantum Skincare's Python FastAPI image processor microservice. Covers FastAPI patterns, Perfect Corp API integration, MediaPipe FaceMesh validation, correlation headers, access control (CIDR + X-Internal-Secret), error handling, Pydantic models, structured logging, mock mode, provider normalization, and testing strategies. Use when working with image-processor code, routes, validation pipeline, Perfect Corp integration, or Python/FastAPI patterns.
Testet REST API Endpoints, validiert Responses, prüft Erreichbarkeit
Generate and validate JSON Schema definitions. Use when asked to create schemas, validate JSON structure, or document API payloads.
Define Vendure database entities extending VendureEntity, with TypeORM decorators, relations, custom fields, and channel-awareness. Use when creating database models in Vendure.
Guide for creating Huma API endpoints following this project's conventions including routing, input/output structs, error handling, and OpenAPI documentation.
