We have some reasonably generic handler support inside OmniFocus, but the only handler that we invoke right now is for clippings, and these have to be wrapped up in a bundle.

If you'd find this feature useful, let us know via Help > Send Feedback, including what situations you'd like to have the invoke the handler.

One of the issues with handlers that I've been mulling over is how to avoid cases where one handler does something that will provoke another handler, that will... etc. In some cases you *do* want to chain multiple handlers so we might just need to detect this at runtime and alert the user and disable the handlers until the next launch, or some such.
