This Skill addresses the lack of unified standards when AI Agents write, review, or refactor NestJS code. In practice, AI-generated code often suffers from disorganized module structures, improper dependency injection, security vulnerabilities, and performance risks, leading to high maintenance costs later.
Usage is simple: you only need to reference the Skill's name or description in the conversation, and the AI Agent will automatically load 40 rules, checking your NestJS code item by item according to priority (from architecture to deployment). You can then trigger specific rules via natural language instructions like "Check this module for circular dependencies" or "Refactor the service to follow the Single Responsibility Principle."
It is ideal for teams or individuals needing to quickly build production-grade NestJS applications, especially those already using AI coding assistants (e.g., Claude, Cursor) for backend development and wanting to ensure code quality, security, and performance. It is also suitable for Code Review scenarios, helping AI assistants standardize review criteria.
We recommend consistently using this tool when starting a new NestJS project or refactoring legacy code. Note that it primarily focuses on NestJS-specific best practices; general TypeScript/Node.js standards still require supplementation with other skills. Rules are prioritized, so it's advisable to address CRITICAL and HIGH-priority rules first.
Key Features
Unlike generic NestJS best practice documentation, this Skill is optimized for AI Agents. Each rule includes a unique prefix (e.g., arch-, di-) and priority labeling, enabling AI to automatically sort and execute them step-by-step, rather than providing just a static reading list.
Limitations
Depends on the NestJS framework version (currently applicable to NestJS 8+/9+), does not cover non-NestJS backend architecture patterns, and requires the AI Agent to have the capability to read the SKILL.md file (supports remote loading via source_url).
FAQ
How do I get an AI Agent to use this Skill?
Simply mention the project context in the conversation or directly say 'Please refer to the nestjs-best-practices skill.' The AI will automatically load the rules and apply them.
What rules does this Skill include?
It includes 40 rules covering ten categories: Architecture, Dependency Injection, Error Handling, Security, Performance, Testing, Database, API Design, Microservices, and DevOps, all sorted by priority.
