Just a little visual inspection to make sure (1) it's clean, (2) the groove isn't so deep that the cable is hanging up in it, and (3) there's still enough of the guide left that the cable isn't contacting the frame.
+1! We've seen a handful of bikes at the shop (including one of my own) where the front shifting went to he!! in a handbasket because the cable was bogging down in the groove of the cable guide.
