# Instrucciones para agentes IA
ai_instructions: |
  Este módulo genera operaciones CRUD completas para cualquier entidad.
  
  Pasos de activación:
  1. Detectar entidades mencionadas en el input del usuario
  2. Generar controladores, servicios y DTOs para cada entidad
  3. Configurar rutas y middleware
  4. Aplicar validaciones y seguridad
  
  Palabras clave de activación:
  - "CRUD", "API REST", "endpoints"
  - "crear", "leer", "actualizar", "eliminar"
  - "controlador", "servicio", "modelo"
  
  Configuración automática:
  - Detectar entidades del esquema Prisma
  - Generar DTOs basados en modelos
  - Configurar paginación y filtros
  - Aplicar middleware de autenticación si está disponible
