Node.js/TypeScript backend expert. Handles Express/Fastify API routes, TypeScript strict mode, Prisma ORM, Zod validation, error handling, configuration management. Use when project is Node.js backend (package.json + TypeScript server).
Governs integration between Next.js 16 frontend and FastAPI backend. Use when connecting APIs, handling JWT auth, configuring CORS, or debugging cross-stack issues.
Builds GraphQL APIs with Apollo Server 4, schema design, resolvers, and data sources. Use when implementing GraphQL servers, building federated graphs, or integrating GraphQL with Node.js frameworks.
Guide tRPC development with routers, services, and client usage. Use when building API endpoints, data fetching, or tRPC procedures.
PRIMARY expert for ALL NestJS and @lenne.tech/nest-server tasks. ALWAYS use this skill when working in projects with @lenne.tech/nest-server in package.json dependencies (supports monorepos with projects/*, packages/*, apps/* structure), or when asked about NestJS modules, services, controllers, resolvers, models, objects, tests, server creation, debugging, or any NestJS/nest-server development task. Handles lt server commands, security analysis, test creation, and all backend development. ALWAYS reads CrudService base class before working with Services.
Generate complete FastAPI project skeleton with SQLAlchemy, MongoDB, JWT auth, Redis cache, Celery tasks, Docker, and CRUD generators. Use when user wants to create or scaffold a FastAPI project.
Guide for advanced Next.js App Router patterns including Route Handlers, Parallel Routes, Intercepting Routes, Server Actions, error boundaries, draft mode, and streaming with Suspense. CRITICAL for server actions (action.ts, actions.ts files, 'use server' directive), setting cookies from client components, and form handling. Use when requirements involve server actions, form submissions, cookies, mutations, API routes, `route.ts`, parallel routes, intercepting routes, or streaming. Essential for separating server actions from client components.
Create complete API endpoints following Clean Architecture. Use when the user wants to add a new endpoint, create an API, implement CRUD operations, or mentions "endpoint", "controller", "API", "REST".
Hono + Drizzle ORMを使用したAPIエンドポイント作成を支援。Usecaseパターンでビジネスロジックをルートから分離。(1)新しいAPIエンドポイント追加、(2)ビジネスロジック実装、(3)エラーハンドリング定義で使用。トリガー：「APIを作成」「エンドポイント追加」「ユースケース作成」「ビジネスロジック実装」
Develop professional REST APIs with Hono framework. Use when creating API endpoints, middleware, validation, error handling, or discussing API architecture with Hono.
Builds content APIs with KeystoneJS, the Node.js headless CMS with GraphQL. Use when creating admin UIs and APIs with automatic CRUD operations, relationships, access control, and TypeScript support.
Develop HTTP APIs, middleware, error codes, and i18n strings using the ginx framework conventions. Use when creating or modifying APIs in apis/, defining error codes, adding i18n strings, or when the user asks to follow project conventions for HTTP endpoints, routes, middleware, or error handling.
Create new Next.js API routes following project patterns. Use when user mentions "new endpoint", "add API", "create route", or "POST/GET handler".
