+## Ejemplo
+
+```go
+code := GenerateWailsCRUD(WailsCRUDSpec{
+    EntityName: "User",
+    Fields:     []string{"Name string", "Email string", "Role string"},
+    WithList:   true,
+    WithGet:    true,
+    WithCreate: true,
+    WithUpdate: true,
+    WithDelete: true,
+})
+// Genera: type User struct + ListUsers + GetUser + CreateUser + UpdateUser + DeleteUser
+```
+
+## Notas
+
+Función pura — genera código como string. Los métodos son stubs con `return fmt.Errorf("not implemented")`. Un agente puede generar el código, insertarlo en app.go, y luego implementar los TODOs.
