Here’s a basic support implementation :

pulic static function siblings( $atts = null, $content = null ) {
  $atts = shortcode_atts( array(
      'depth' => 1,
      'class' => '',
      'include_current' => 0,
      'sort' => ''
    ), $atts, 'siblings' );
  global $post;
  $return = wp_list_pages( array( 'title_li' => '',
      'echo' => 0,
      'child_of' => $post->post_parent,
      'depth' => $atts['depth'],
      'exclude' => (int) $atts['include_current'] ? '' : $post->ID,
      'sort_column' => $atts['sort']
    ) );
  return ( $return ) ? '<ul class="su-siblings' . su_ecssc( $atts ) . '">' . $return . '</ul>' : false;
}

Shortcode

[su_siblings depth="0" include_current="1" sort="menu_order"]
