style-queue (or something) should r- patches missing ChangeLogs Or at least make a nasty comment in the bug. Rarely can one actually review a patch w/o a ChangeLog. We have at least one other bug about our tools warning us sooner, but if style-queue is the earliest we can get a warning, then so be it. It's better than the current pre-commit hook or reviewers spending time on it. The bot should point people to http://webkit.org/coding/contributing.html or possibly http://webkit.org/coding/contributing.html#changelogs
A helpful comment would be OK, but you'd need to nominate the tool for reviewer status to actually r-. And there are cases when it makes more sense to just manually adapt and land a one time contributor's patch than to educate them about our process. Sometimes people do useful things without long-term involvement with the project.
