This is just about the laziest and least trustworthy language possible to use. Your reports aren't going to know what they don't know and are just going to become paranoid and work slower. The code quality will likely not improve from a conversation prompted this way. This is also a continuous process, not a magic high stakes meeting. If you're in charge you should see patterns in the code reviews and know what their knowledge gaps are causing these issues. They're looking to you for help if you're the one bringing this up in the first place.
If that's too time consuming or over your head you should not be a manager. Leverage your own knowledge and use mentorship to avoid conflicts with your reports and the improved productivity will please the people above you as well. You aren't giving anyone what they need by merely communicating requirements. Your job is to fulfill those requirements with the team you have.
