My question is regarding posts that are of the form "Is my proof correct?" without having the [solution-verification] tag explicitly.
The guidelines for the tag say: "For posts looking for feedback or verification of a proposed solution. "Is my proof correct?" is too broad or missing context. Instead, the question must identify precisely which step in the proof is in doubt, and why so."
However, do these guidelines still apply to the question even though it doesn't have the tag? And would the correct course of action to be to add that tag to the post if it applies?
Regarding the latter question, it seems appropriate to add relevant tags. On the other hand, it feels slightly rude to add a tag to someone's post and then say that their question doesn't follow the guidelines for the tag.
