The special page should somehow show which pages on a site are linked to an item. Preferably this should be done in such a way as to make it easy and efficient to create new items for missing ones.

The special page could also do an additional pass to check if the items are "complete" given the existing sitelinks in the items and the langlinks in the pages. This could imply that the query to the external site should use a generator list and not only a basic list.
