I'm thinking of creating a tag called proof-creation, where the tag will be for questions asking about how to start a proof, since I haven't seen it before. Thoughts?
I suppose other users will add their viewpoints or some further details, but what I will mention at least a few points related to the tag proposal which skip into mind immediately:
- It is a "meta-tag", we should try to keep number of such tags at minimum.
- The proposed tag seems rather similar to proof-strategy, which was deleted some time ago, see the discussion here and here.
- And the tag is also somewhat similar to hint-only tag, which was proposed before, but after some discussion the consensus was that it would probably not be very useful. See here: Suggestion for "Hint-Only" Tag.
My opinion is that (similarly as with hints) the OP can simply state in their question that they have problem to get started and they want to try to finish the proof by themselves if they have some suggestions what to do first. (Although maybe something like this can be more effectively done in chat than on the main.) It's up to the answerers to which extent they decide to honor such request and whether they will add full solution. (Maybe some answerers will add full solution later, after the OP received enough help. And perhaps in some cases the OP will be able to finish the proof and they will post self-answer.)
I will also mention that the tags starting with proof tend to be used incorrectly. You can see that many users simply put proof-theory or proof-writing or proof-strategy to any question which asks for proof of something. This is definitely not how those tags should be used. So we would be adding one more tag which could cause similar issues. However, this is not argument against the tag itself. This is only showing that some users use the tags rather carelessly. (Still, if we can we should name the tags in such way that it will be intuitively clear already from the name what the tag is intended for.)
