Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.04043 |
| Opus 5.5 | $0.00022 | $0.01617 |
| Sonnet 5.5 | $0.00011 | $0.00809 |
| Haiku 4.5 | $0.00005 | $0.00404 |
Grade A, and why
nestjs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 690 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NestJS Development Skill — Enterprise TypeScript Framework
This skill provides comprehensive NestJS development patterns for building scalable, testable, enterprise-grade Node.js applications with modular architecture and decorator-driven design.
Key Principles
- Modular Architecture: Organize code into feature modules with clear boundaries
- Dependency Injection: Let the container resolve and inject dependencies
- Decorator-Driven: Use decorators for metadata-driven behavior (routes, validation, guards)
- Separation of Concerns: Controllers handle HTTP, Services handle logic, Modules wire it together
Module Structure
Feature Module
import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { ProductsController } from './products.controller';
import { ProductsService } from './products.service';
import { Product } from './entities/product.entity';
import { ProductRepository } from './repositories/product.repository';
@Module({
imports: [TypeOrmModule.forFeature([Product])],
controllers: [ProductsController],
providers: [ProductsService, ProductRepository],
exports: [ProductsService],
})
export class ProductsModule {}
Module Types
| Type | Purpose | Example |
|---|---|---|
| Feature Module | Group related features | ProductsModule |
| Shared Module | Reusable across features | DatabaseModule, LoggerModule |
| Global Module | Available everywhere | ConfigModule, AuthModule |
| Dynamic Module | Configurable at registration | TypeOrmModule.forRootAsync() |
Shared Module Pattern
@Module({
providers: [LoggerService, DateService],
exports: [LoggerService, DateService],
})
export class SharedModule {}
// Used in feature modules
@Module({
imports: [SharedModule],
// LoggerService and DateService now available for injection
})
export class OrdersModule {}
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nestjs is a skill published in the GitHub repository Omar-Obando/qwen-orchestrator (52 stars, last pushed 4mo ago), licensed MIT. It adds 54 tokens to every session and 4,043 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
