The user story is a promise to have a conversation. I think that is usually well understood. From there I think you can fall into two camps: that conversation should result in a Jira/whatever ticket with all the requisite documentation for an agile team versus that conversation IS the essential information required to properly build the expected valuable working software.

Back to the question - what do you do about poor knowledge transfer in a project? I think a moderate de-emphasis on thinking of the user story text and the additional info like acceptance criteria etc. as self-sufficient documentation and adding more emphasis on that close relationship between developer, user, and maybe a tester, can help fill in big knowledge gaps.
