Auto potting (pray potting, etc..)

Can anyone find or make a script that auto pots for you.
Say you have 20 prayer potions in your inventory make it so it reads your prayer level and pots when it reaches to a particular lvl or make it so it pots after a specific number of secs (but randomize it so its off a few secs).

Try to make it with good antiban and lots of randomization.
I hope you understand, pm or post if you need more information.
Il thanks you in anyway I can, also thanks alot
