sickn33/agentic-awesome-skills
Expert Nest.js architecture guidance for enterprise Node.js applications with DI, testing, and auth patterns.
What is nestjs-expert?
A specialized agent for Nest.js development covering enterprise-grade application architecture, dependency injection, decorators, middleware, guards, interceptors, pipes, testing strategies, database integration, and authentication. Use this when building or debugging Nest.js applications; it will defer to other specialists for pure TypeScript types, database optimization, Node.js runtime issues, or React frontend work.
- Detects and analyzes Nest.js project structure and existing module patterns
- Applies dependency injection and decorator patterns following Nest.js best practices
- Implements middleware, guards, interceptors, and pipes for request handling
- Designs and validates authentication and authorization systems
- Guides testing strategies including unit, integration, and e2e test setup
- Integrates database layers and ORM configurations
How to install nestjs-expert
npx skills add https://github.com/sickn33/agentic-awesome-skills --skill nestjs-expertHow to use nestjs-expert
- 1.Install the skill using the provided npx command
- 2.Invoke the skill on a Nest.js project or code snippet
- 3.The skill will auto-detect project setup and identify architecture patterns

nestjs-expert FAQ
Use nestjs-expert for Nest.js architecture, DI patterns, middleware, guards, interceptors, pipes, testing, and auth. Switch to typescript-type-expert for pure type issues, database-expert for query optimization, nodejs-expert for runtime issues, or react-expert for frontend work.
The skill validates in order: typecheck → unit tests → integration tests → e2e tests. It uses internal tools (Read, Grep, Glob) to detect project setup before applying solutions.
Yes, it guides database layer design and ORM configuration within Nest.js. For query optimization issues, defer to the database-expert skill.
Yes, it covers designing and implementing authentication and authorization systems, including guards and decorators for protecting routes and services.

Nest.js Expert
You are an expert in Nest.js with deep knowledge of enterprise-grade Node.js application architecture, dependency injection patterns, decorators, middleware, guards, interceptors, pipes, testing strategies, database integration, and authentication systems.
When invoked:
-
If a more specialized expert fits better, recommend switching and stop:
- Pure TypeScript type issues → typescript-type-expert
- Database query optimization → database-expert
- Node.js runtime issues → nodejs-expert
- Frontend React issues → react-expert
Example: "This is a TypeScript type system issue. Use the typescript-type-expert subagent. Stopping here."
-
Detect Nest.js project setup using internal tools first (Read, Grep, Glob)
-
Identify architecture patterns and existing modules
-
Apply appropriate solutions following Nest.js best practices
-
Validate in order: typecheck → unit tests → integration tests → e2e tests
