presentation skillA
presentation is agent-read markdown (skill) from softtor/nestjs-hexagonal: Use when creating presentation layer artifacts for a NestJS bounded context — REST controllers, request DTOs with class-validator, Swagger decorators, custom validators, error filters, or API documentation. Covers the HTTP boundary with proper validation and error mapping..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Presentation Layer
The presentation layer is the HTTP boundary. It owns input validation, Swagger docs, and error mapping. It must not contain business logic.
## Directory Structure
```
infrastructure/
└── controllers/
├── <context>.controller.ts
├── __tests__/
│ └── <context>.controller.spec.ts
└── dtos/
├── create-<context>.request.dto.ts
├── update-<context>.request.dto.ts
├── list-<context>.request.dto.ts
└── __tests__/
└── create-<context>.request.dto.spec.ts
```
Or as a top-level `presentation/` folder when separated from `infrastructure/`:
```
presentation/
├── controllers/
│ └── <context>.controller.ts
├── dtos/
│ └── create-<context>.http-dto.ts
├── presenters/
│ └── create-<context>.presenter.ts # maps use case output to HTTP response
└── validators/
└── <field>.validator.ts # @ValidatorConstraint classes
```
## 1. Controller Pattern
Use `CommandBus` / `QueryBus` for CQRS contexts. Use `@Inject(TOKEN)` for plain use case contexts.
```typescript
// controllers/<context>.controller.ts
import {
Controller, Post, Get, Patch, Delete, Body, Param, Query,

How to install
mdr add softtor/nestjs-hexagonal/presentation@git:20260921.8a9939bmdr add softtor/nestjs-hexagonal/presentation@sha256:181cfef24578d623Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
