What it does
When installed, the agent follows a set of Node.js backend best practices whenever you ask it to build a server or API. It draws on patterns for middleware, error handling, authentication, database connections, and API design, and it recommends things like TypeScript, input validation with Zod or Joi, environment variables for secrets, structured logging, rate limiting, and health checks. A reference document with deeper worked examples is available for the agent to read when needed.
Great for
- Developers starting a new Express or Fastify REST API or GraphQL backend
- Teams that want consistent error handling, validation, and logging conventions across services
- Developers building microservices who want a checklist of production concerns
Skip it if
- Beginners who need step-by-step tutorials, since the skill is a concise set of guidelines rather than a course
- Projects on other backend stacks such as Python or Go, where the guidance does not apply
Try asking
- “Create an Express REST API for a todo app with JWT authentication and input validation”
- “Set up a Fastify backend with PostgreSQL connection pooling and health check endpoints”
- “Review my Node.js server structure and suggest improvements for error handling and graceful shutdown”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Name the framework (Express or Fastify) and database you plan to use so the guidance matches your stack
- Point the agent at your existing project so it adapts patterns to your code rather than generating from scratch
- Pair with a dedicated testing skill, since this skill only refers to one for testing guidance
