Anyone have suggestions for getting some tools in place to monitor for when changes happen that match certain criteria (obvious one being when certain files change)? Hosting-wise, we use BitBucket Cloud, though I can't find anything built-in that'd be useful (seems like most cloud-based solutions don't offer pre-receive hook customisation?)

We've had some "issues" with people not considering the impact of changes to certain code, and just want a little more handholding before the next time that sort of issue happens. I'm sure I could rig something either with a webhookey endpoint, or a CI build that does it, but it just seems like the sort of thing there'd be a pre-built tool for.

Any ideas?
