This skill should be used when the user asks to "create barrel exports", "add index.ts", "organize exports", "create entity", "add DTO", "create service", or when adding files to NestJS module directories. Auto-maintains barrel exports.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Barrel Export Manager
Auto-creates and maintains `index.ts` barrel export files in NestJS modules for clean, maintainable imports.
## Activation Triggers
This skill activates when:
- Creating new entity, DTO, service, controller, guard, decorator
- Adding files to module directories
- Organizing NestJS module structure
- Mentioning "NestJS", "module", "create"
- Importing from module directories
## Required Pattern (MANDATORY)
Every NestJS module folder MUST have `index.ts` barrel exports:
```
users/
├── entities/
│ ├── user.entity.ts
│ ├── profile.entity.ts
│ └── index.ts # ✅ Barrel export
├── dto/
│ ├── create-user.dto.ts
│ ├── update-user.dto.ts
│ └── index.ts # ✅ Barrel export
├── services/
│ ├── users.service.ts
│ └── index.ts # ✅ Barrel export
└── controllers/
├── users.controller.ts
└── index.ts # ✅ Barrel export
```
## Auto-Management Process
### Step 1: Detect New File
When user creates:
```typescript
// users/entities/user.entity.ts
@Entity('users')
export class User {
@PrimaryGeneratedColumn('uuid')
id: string
// ...
}
```
### Step 2: Auto-Create/Update index.ts
…Read the whole file at its exact version.
How to install
mdr add smicolon/ai-kit/barrel-export-manager@sha256:88f77560cdfdc4d1The line at the top of this page pins the label git:20260903.50c14ca, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
