Persistent preferences for AI behavior

It would be very useful to be able to set some AI behavior preferences just once — for example:

“Don't generate content without doing a search first”

“If you don't find verifiable sources, tell me explicitly.”

“Don't make up dates, names or quotes”

Currently, these instructions have to be repeated with each new session, which is inconvenient and leads to avoidable errors.

An “AI Preferences” section in the user profile - similar to a customizable system prompt - would solve the problem in an elegant way and would make the tool much more reliable for those who use it in professional or educational settings.
