This is a link to the download page for the Mantis Combat System downloads page. I've got Mantis' Autosipper up there, which is up-to-date and working properly. It's geared for Lusternia, but the prompt is very easy to change, as are the trigger lines if necessary.
Download it, change whatever it is you need to, and voila! It uses Mudlet's filtering systems instead of hard-coding every possible detail, which makes the code a lot smaller and easier to handle.
