add_menu_page Callback Function: Skip page content?

add_action( 'admin_menu', 'av_subscribe_create_menu' );

function av_subscribe_create_menu()
{
    $hook = add_menu_page(
        'Add Comment Feed',
        'Add Comment Feed',
        'manage_options',
        'av-create-feed', // Don't use __FILE__ as the slug, keep it short 'n sweet!
        '__return_true' // We need a callback otherwise WP won't properly handle the page, though it's never seen
    );


    if ( $hook ) // Current user has the right caps
        add_action( "load-$hook", 'av_subscribe_create_feed_page' ); // This runs before header output 
}

function av_subscribe_create_feed_page()
{
    $page_id = wp_insert_post( array(
        'post_status' => 'publish',
        'post_parent' => 13570,
        'post_title' => 'My Title',
        'post_type' => 'page',
    ));

    if ( $edit_url = get_edit_post_link( $page_id, 'raw' ) )
        wp_redirect( $edit_url );
    else
        wp_redirect( admin_url( "edit.php?post_type=page" ) ); // Fallback

    exit;
}

If you do not specify a title, but you specify the post_status as publish, will this automatically create a slug for you?

It certainly will! Check the source code for wp_insert_post().
