name: dto-generator description: Scaffolds NestJS DTOs with class-validator and @nestjs/swagger decorators.

DTO Generator

This skill automates the creation of Data Transfer Objects (DTOs) following the project's standards for validation and documentation.

Workflow

1. Identify the DTO name: Use PascalCase (e.g., CreateUserDto, UpdateProfileRequest).
2. Identify the module and type: Requests go to dto/requests, Responses to dto/responses.
3. Execute the generator script: Provide the name and module.
4. Define properties: The script will prompt or you can edit the file to add specific fields.

Usage

Run the following command from the project root:

node .gemini/skills/dto-generator/scripts/generate_dto.cjs <module-name> <dto-name> <type: request|response>

Example

To create a UpdatePasswordRequest in the auth module:

node .gemini/skills/dto-generator/scripts/generate_dto.cjs auth UpdatePasswordRequest request

This will:

• Create src/modules/auth/dto/requests/update-password-request.dto.ts.
• Scaffold the class with @ApiProperty and basic class-validator placeholders.

Standards Applied

• File Naming: kebab-case (e.g., update-password-request.dto.ts).
• Validation: class-validator decorators.
• Documentation: @nestjs/swagger decorators.
