Implementation

@override

    Logger.info('Usage: karna feature <feature_name>');
    return 64;
  }

  final featureName = argResults!.rest.first;
  final memoryAware = argResults!['memory-aware'] as bool;

    Logger.error(
      'Feature name must be snake_case (lowercase letters, numbers, underscores).',
    );
    return 64;
  }

  // Check we're in a Flutter project
