AFAIK the only tooltip support in AUCTeX is for revealing folded buffer content; see the end of (info "(auctex) Folding") [0]. One way to find the documentation of a package at point is with the commands TeX-documentation-texdoc or TeX-doc; see (info "(auctex) Documentation") [1]. I'm not aware of any commands for briefly summarising that information, though. I'm sure the AUCTeX experts here will know better.

With or without Ivy, AUCTeX can complete even the start of a macro '\'. > 2. Some commands, say, `\href', will not be automatically completed at all. This is not an issue with Ivy; see my reply on the Ivy issue tracker: https://github.com/abo-abo/swiper/issues/2887#issuecomment-860617241 -- Basil
