I'm pretty sure only attack rolls auto-fail on a roll of one, skills and other things can succeed on a 1 if you have high enough bonus.
On the other hand they don't auto-suceed on a 20 either
I'll just stay out of the Rules Questions forum XD That's the 2nd time today I've been wrong.
Being wrong is how you learn. Nothing helps you think about a rules interpretation like having to sit down and think about your position while someone else is presenting theirs.
