The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructs the user to install @nestjs/swagger via npm. This is the official and well-known documentation package for the NestJS framework.
[COMMAND_EXECUTION]: Provides a script (generate-openapi.ts) that programmatically creates the NestJS application context to generate an OpenAPI JSON file and write it to the local filesystem using fs.writeFileSync. This is a standard procedure for generating API contracts during build or CI/CD phases.
[DATA_EXPOSURE]: The skill explicitly promotes the use of @ApiHideProperty() to ensure sensitive internal fields (such as user IDs or privacy-sensitive data) are not exposed in the generated Swagger UI or OpenAPI documentation. It also provides examples of using the ValidationPipe with whitelist: true to prevent mass-assignment vulnerabilities.
