I'm a big proponent of saying "you succeed without a roll because you have relevant expertise and there's no serious pressure", so that's a good move.
Handy is basically a more limited version of Jack of All Trades. Handy lets you add another practical skill in which you use your hands (mechanic, carpenter, etc), but Jack would let you add any vocation. Jack is an opportunity to have your armored juggernaut warrior say "Yes, I've read a book or two. Before I joined the army, I actually went to medical school."
