+If you want to pass additional context to your custom exception, use `Illuminated\Console\RuntimeException`:
+
+```php
+class Foo extends Command
+{
+    use Loggable;
+
+    public function handle()
+    {
+        throw new RuntimeException('Oooups! Houston, we have a problem!', [
+            'some' => 123,
+            'extra' => true,
+            'context' => null,
+        ]);
+    }
+
+    // ...
+}
+```
