What it does
When a user is building a NestJS (a TypeScript framework for server-side APIs) project, this skill tells the agent to follow a set of recommended conventions: organise code into feature modules, keep controllers thin and put logic in services, validate incoming request data with class-validator DTOs, protect routes with guards, return one consistent error format, and validate configuration at startup. It also includes example code snippets and testing guidance. It is a set of written guidelines rather than a tool that does work on its own.
Great for
- Developers building or refactoring a NestJS API and wanting consistent structure
- Teams who want a shared checklist for validation, auth guards and error handling
- Developers new to NestJS who want the agent to follow common production conventions
Skip it if
- Projects not using NestJS or TypeScript, since the examples will not apply
- Security-critical systems that rely on this skill alone; it gives general patterns, not an audit, and the auth examples are illustrative only
Try asking
- “Create a new NestJS users module with a controller, service and validated create DTO”
- “Review my NestJS controllers and move business logic into services”
- “Add a global validation pipe and a consistent error filter to my NestJS app”
- “Write unit and request-level tests for my NestJS guards and pipes”

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 your framework version and database layer in the request so the agent picks matching APIs
- Ask the agent to adapt the example snippets to your existing folder layout rather than copying them verbatim
- Still review generated auth, rate limiting and config code yourself, since the skill lists these as requirements without a full implementation
