It's been a while (if ever) since this question has last been asked. I'd like to get an idea of what scripts everyone finds useful. If you just want to throw up what's in your ;favs list that's fine, but as needed scripts like ;narost would be helpful to name as well.
A list of what has been named so far:
Utility:
autoforage - Procures large numbers of herbs as well as raw materials for ranger imbeds.
betazzherb - forages for the herb which you specify. Works with bounties.
sloot - loots & skins monsters, and puts their treasure in designated containers. It also will sell your stuff in town to the appropriate shop, including getting your boxes picked.
crosscharcom - lets me send commands like accept or other commands.
roomcreature - Announces when creatures enter the room via non-standard messaging.
useherb- go through the container specified (;useherb cloak) and find herbs to heal down your wounds.
herbheal - uses useherbs to heal down your wounds, but will also go to the bank and then to the herbalist when you don't have the right herb for your current wound.
scroll - search all your containers for scrolls, read them, and then allow you to cast them using ";scroll [spell number]". Handy if you have a bunch of them tucked away.
useimbed - tracks charges of your magic items.
chargeimbed - Aids with charging magic items.
swapbounty - exchanges your current Adventurer's guild task for a new one.
calipers - will give you a handy breakdown of any trap you find, including consequences for failure. More available if you use actual calipers.

foreach - Do some things with everything in your inventory, container, on the ground, or in your locker. Examples: ";foreach scroll in satchel;read item" or ";foreach noun=ticket in inv;get item;bundle" or ";foreach box in inv;get item;put item in locker" or ";foreach gem in sack;get item;put item in gemcutter;turn gemcutter;get item from gemcutter;put item in sack". By default it matches based on item type (not name), see docs for how to match by name/noun.
