Backend Database Expert

Backend patterns for ORPC routers, Drizzle schemas, and server-side code. Use when creating API endpoints, database tables, or services.

Authentication middleware for Express.js and Node.js applications. Use when building Express APIs that need JWT authentication, OAuth, or custom auth strategies. Provides 500+ authentication strategies. Choose Passport.js over Auth.js for Express backends, pure API servers, or when you need maximum control over auth flow.

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).

专注于 Node.js 后端开发模式与最佳实践。

Create and manage database schema migrations with reversible operations, zero-downtime deployments, and safe rollback strategies. Use this skill when writing database migrations for PostgreSQL, MySQL, SQLite, MongoDB, or any database system; when using ORMs like Prisma, Sequelize, TypeORM, ActiveRecord, Django ORM, or similar migration tools; when implementing schema changes (adding tables, columns, indexes, constraints); when performing data migrations or transformations; when creating indexes on large tables with concurrent options to avoid locks; when separating schema changes from data migrations for safer rollbacks; when implementing zero-downtime deployment strategies for high-availability systems; when versioning database schemas and managing migration order; or when working with database change management in production environments.

Skill para diseñar y construir backends y APIs **modulares**, **auditables**, **resilientes** y **multi-tenant**, con seguridad fuerte, modelado correcto (incl. ledger cuando aplique), datos y jobs/colas operables.

Comprehensive backend development guide for Node.js/Express/TypeScript microservices. Use when creating routes, controllers, services, repositories, middleware, or working with Express APIs, Prisma database access, Sentry error tracking, Zod validation, unifiedConfig, dependency injection, or async patterns. Covers layered architecture (routes → controllers → services → repositories), BaseController pattern, error handling, performance monitoring, testing strategies, and migration from legacy patterns.

Complete backend development guide covering Node.js, Python, Go, Java, PHP, databases, APIs, authentication, and server architecture. Use when building server applications, APIs, or backend systems.

A complete back-end specialist skill for designing scalable architectures, robust APIs, and secure server-side systems.

Backend expert guidance for API/DB/Security/Architecture

Build robust backend systems with modern technologies (Node.js, Python, Go, Rust), frameworks (NestJS, FastAPI, Django), databases (PostgreSQL, MongoDB, Redis), APIs (REST, GraphQL, gRPC), authentication (OAuth 2.1, JWT), testing strategies, security best practices (OWASP Top 10), performance optimization, scalability patterns (microservices, caching, sharding), DevOps practices (Docker, Kubernetes, CI/CD), and monitoring. Use when designing APIs, implementing authentication, optimizing database queries, setting up CI/CD pipelines, handling security vulnerabilities, building microservices, or developing production-ready backend systems.

Master TDD orchestrator specializing in red-green-refactor discipline, multi-agent workflow coordination, and comprehensive test-driven development practices. Enforces TDD best practices across teams with AI-assisted testing and modern frameworks. Use PROACTIVELY for TDD implementation and governance. Use when: the task directly matches tdd orchestrator responsibilities within plugin backend-development. Do not use when: a more specific framework or task-focused skill is clearly a better match.
