Now in this thread I am lumping exploration and non-combat together. Also, this is of course my pure opinion.
I feel like actual rules for this are a waste of time. I feel like having tools and letting players decide what to do with them would be better. I know in my games the players like to come up with uses for what they have on hand whether it's skills, spells, or items. I find things like Skill Challenges from 4th edition to be an aweful attempt at this. Sometimes players will create instances that the DM didn't even plan just by using what they have and a little imagination.
