The agent isn't part of the team or the school. It just like the dead recruiting period where College Coaches can go watch a recruit play another sport, cannot in any way communicate with the recruit, but they are allowed to talk to the player's coaches.
Once the NCAA allowed kid's to have NIL agents -- circumventing NCAA rules are beyond easy. Schools can recruit players from other schools without ever saying a word to the player. They can simply go thru the agent, who isn't involved with the team/school.
