Restrict changeset comment name
3 answers
This help topic lists and describes the predefined preconditions and follow-up actions: Operation preconditions and follow-up actions. I don't see one that requires that change set comments contain a specific string.

Since there is no out of the box precondition, you would have to create a custom solution. See https://rsjazz.wordpress.com/2012/11/01/restrict-delivery-of-changesets-to-workitem-types-advisordelivery-of-changesets-associated-to-wrong-work-item-types-advisor/ for how that could be done.
