I think the answer to "how will AI agent guidelines be enforced" is that they won't be because they can't be, at least not directly.

This doesn't mean that this approach doesn't have value though. I think it very much does.

One way to indirectly enforce use of the AI agent guidelines is via an oral examination where the instructor and student look over their work together and talk about it. Students who have genuinely tried to learn and used AI as a learning tool via the agent guidelines should do a lot better in an oral exam than students who have used AI as a solution generator.

I adopted the oral exam (without agent guidelines) for a course i teach in the academic year just gone, it worked pretty well. Next term I intend to include the agent guidelines to give them clearer guardrails. Still ultimately optional, but if students choose to ignore them it's gonna be pretty obvious during our conversation.
