I see that you have created (yang-mills-theory) tag. It might be useful to create also tag-wiki or at least tag-excerpt. It might help other users to use the tag correctly. (This is probably not a problem here, since the tag name seems to be descriptive enough.) Another reason is that the tags used on only one question are automatically deleted after certain time unless they have tag-wiki. — Martin Sleziak 2 mins ago
Perhaps it is sometimes reasonable to post a reminder such as the above - at least for the tag which have potential to become useful tag.
A few days ago the tag has been removed because it was used only on single question. (Although perhaps that tag would probably not be that useful, so in that case this is no real harm.)

The tag-info for is is a somewhat unusual state, since it has no tag-excerpt - as the suggested edit has been rejected - but it has a tag-wiki.
