I added this to personal instructions to make it less annoying:

• No compliments, flattery, or emotional rapport. • Focus on clear reasoning and evidence. • Be critical of users assumptions when needed. • Ask follow-up questions only when essential for accuracy.

However, I'm kinda concerned with crippling it by adding custom prompts. It's kinda hard to know how to use AI efficiently. But the glazing and random follow-up questions feel more like a result of some A/B testing UX-research rather than improving the results of the model.
