Our review
Expert in implementing enterprise NestJS applications with Clean Architecture and strict TypeScript.
Strengths
- Enforces clean architecture and strict TypeScript for maintainability.
- Exception-based error handling separates domain concerns from HTTP layer.
- Multi-database support (PostgreSQL, MongoDB, Redis) for different data requirements.
- Exclusive use of Yarn for package management and script execution ensures consistency.
Limitations
- May be overly opinionated for simple projects.
- Requires familiarity with Clean Architecture and NestJS.
- Only supports Yarn, not npm or pnpm.
When building enterprise-grade NestJS applications requiring structured architecture and strong typing.
For small prototypes or projects where speed of development outweighs architectural rigor.

Examples
Create a new NestJS module for user management following Clean Architecture: presentation layer with DTOs and controller, application layer with use cases and domain exceptions, domain layer with entities and interfaces, infrastructure layer with repositories and entities. Use strict TypeScript and Yarn.Implement exception-based error handling in my NestJS application. Create a custom domain exception for 'UserNotFoundError' and handle it in the global exception filter to return a proper HTTP response.Configure NestJS to connect to PostgreSQL for metadata, MongoDB for logs, and Redis for caching. Use TypeORM for PostgreSQL, Mongoose for MongoDB, and ioredis for Redis. Ensure the configuration is environment-aware.name: nestjs description: Expert in implementing enterprise NestJS applications with Clean Architecture, strict TypeScript, and event-driven design. Supports Yarn build system and production-ready patterns.

Overview
Expert in implementing enterprise NestJS applications with Clean Architecture and strict TypeScript.
Rule Categories
| Priority | Category | Impact | | :--- | :--- | :--- | | 1 | TypeScript Standards | HIGH | | 2 | Error Handling | MEDIUM |
Core Expertise
- Clean Architecture: Presentation → Application → Domain → Infrastructure.
- Strict TypeScript: No
any, explicit types, and concrete interfaces. - Exception-Based Error Handling: Domain exceptions (not HTTP exceptions) in application layer.
Instructions for the Agent
- Consult Internal Rules: Always refer to the
rules/directory within this skill for TypeScript standards and error codes. - Yarn Only: Use Yarn exclusively for package management and script execution.
- Multi-Database: Use PostgreSQL for metadata, MongoDB for high-volume logs, and Redis for ephemeral state.
