Automated summary
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.
Security analysis
SafeThe skill instructs an AI agent on NestJS development patterns using TypeScript, clean architecture, and specific tools like Yarn. It does not contain any destructive commands, exfiltration, or obfuscated payloads.

How this analysis is madeExamples
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.

Skill: NestJS Backend Development
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.
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/enterprise-nestjs-backend-development-mmh8qrwy/download' --output '.skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy/SKILL.md.part' && mv '.skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy/SKILL.md.part' '.skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy'openskills read 'enterprise-nestjs-backend-development-mmh8qrwy'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/enterprise-nestjs-backend-development-mmh8qrwy/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
