When to Use

Use this skill when you need to add a new backend route under apps/backend/src/* and want it to be:

• consistent with existing modules
• observable (metrics/logs)
• documented in Swagger

Guardrails

• Keep the global prefix api (routes are under /api/*), except /metrics.
• Use class-validator DTOs.
• Update Swagger decorators on controllers.

Template

1. Create DTO
   • apps/backend/src/<domain>/dto/<name>.dto.ts
   • Use class-validator (IsString, IsOptional, MaxLength, etc.)
