Hey I am trying to create a new item so I can file news away automatically here is the code I have.

using System;
using System.Collections.Generic;
using Umbraco.Hive;
using Umbraco.Framework.Tasks;
using Umbraco.Framework.Context;
using Umbraco.Framework;
using Umbraco.Cms.Web.Context;
using Umbraco.Cms.Web.Tasks;
using Umbraco.Cms.Web.Model;
using Umbraco.Cms.Web;


namespace Umbraco.Gravypower.Whirrakee.Kernel.Tasks
{
    [Task("25876d45-b834-48be-a2f5-5f5f024a458b", TaskTriggers.Hive.Revisions.PostAddOrUpdate, ContinueOnFailure = false)]
    public class FileNews : AbstractTask
    {
        private IUmbracoApplicationContext _appContext;

        public FileNews(IFrameworkContext context, IUmbracoApplicationContext appContext)
            : base(context)
        {
            _appContext = appContext;
        }
        public override void Execute(TaskExecutionContext Context)
        {
            var cms = _appContext.Hive.Cms();

            //gets the item that has triggered this task
            var currentItemID = ((HiveRevisionPostActionEventArgs)Context.EventArgs.CallerEventArgs).Entity.Item.Id;
            var currentItem = cms.Content.GetById(currentItemID);
            if(currentItem != null)
            {
                if (currentItem.ContentType.Alias == "news")
                {
                    //grab the new folder
                    var newsFolder = cms.Content.GetById(Constants.Content.NewsFolder);

                    //gets the date
                    var date = currentItem.Attributes["date"].DynamicValue;
                    var year = (int)date.Year;
                    var yearFolder = newsFolder.Children().SingleOrDefault<Content>("NodeTypeAlias == @0", year);

                    if (yearFolder == null)
                    {
                        var yearFolderName = year.ToString();
                        var hiveManager = (IHiveManager)cms;
                        var contentBuilder = hiveManager.Cms().NewRevision(yearFolderName, yearFolderName, "newsFolder")
                            .SetParent(newsFolder.Id)
                            .Publish()
                            .Commit();

                        yearFolder = contentBuilder.Content;
                    }
                }
            }
        }
    }
}
