You don't. (to both questions) I don't know about you - but I can spot it by glancing through MR and just expect code provider to explain his solution in description or be "obvious" to me. So sulution to not having these problems is code review. And if you have this problem then well, you have bigger problem (bad CR). But fixing it all at once is bad idea. Just fix modules you are working with/at. EDIT: I spot it by checking imports/exports and API surface, so could be automated.
