I do wonder if "without my approval" is looser than "discuss only, do not make edits"? I'm not sure how much that finegrain thing matters in prompts nowadays tho

One problem is that agents are notoriously bad at handling ‘me’ vs ‘you’ over an extended conversation. ‘Without my approval’ far back in the context of an extended session gets fuzzy about who ‘me’ is.

This has always seemed strange to me. It will offer a suggestion, I'll make a comment about a suggestion, and it returns with, "Your suggestion..." The further distance from the suggestion, the more likely it confuses who made it.
