it's free and has a good agility script built in...just aim your camera all the way up. You have to add bots to do randoms manually...idk how to do it, still learning.
Don't get RSBots.net's agility bot; it's the exact same bot as Perfect Agility from www.rsbotting.com but it's cheaper if you buy Perfect Agility. They're both great bots, though--they're not flawless, but they're the best bots out there. Perfecticus just updated them, too, if I'm not mistaken.
