/persona command for user

[loveMEnnui]

i want a universal persona command that ai see

[enclavum]

What would it do? Currently, you can tell AI you are playing a character with /me Andre: tell me something.

[loveMEnnui]

i mean something like :
You set /persona

Put your personality/background/preferences into it
The AI sees that persona in every conversation
Character cards don't need to repeat your persona
It stays active until you change/clear it

That would be like SillyTavern's user description? If so, it would also need a name. And how would it be sent on /context?
