If we change skip_patterns to a tuple instead of a list, we can just use the str.endswith() function to checking for matches instead of iterating over a list.

Hey @TheSecondAmigo – thank you for this contribution. We had some refactoring in flight related to this script. I think it makes sense to go ahead and close this PR for now. If you are interested in contributing, that is awesome! Please be on the lookout for "good first issue" Issues, which we plan to add as we ramp up this newly open-source project.

Thanks again for your interest!
