There arnt any cp pots scripts... walker does not keep track of cp pots...
In the options you can set it to use cp pots instead of hp pots but you gotta keep an eye out to use too many.
Set it to use if ur hp is < 99%
Unless it was added to one of the latest walkers but i dont think they did.
Just the normal l2encdec and then L2ClientDat i had on my pc for a long time now...
I tried l2fileedit or what ever that thing is called but never could get it to work...
