Very bad idea for someone who leaves their bike locked outside. I would never leave my tools or other personal belongings inside a trunk bag or saddle bag, not only can they get stolen but a bike thief getting hold of tools will have a time of his life. It's better to have a small backpack or something and keep those things on person. Non-cycling specific clothing with lots of pockets is also very practical.
