I'll explain everything over Discord about it if you want. Also to point out, this is already possible by adding jump bats to the config. It would seem very silly to go and make an entire new FLHook command to do something that has already been done. When the autobuy plugin was redone by Alley, it was to add this extra functionality. If we simply renamed the cloak element to "special" or something, then add all FLHook based equipment to that, we'll save a lot of time and effort for an unneeded change.
(adding this to autobuy.cfg will, in the meantime, allow jump bats to be auto bought when the cloak bit is enabled. It's a very easy change to make it so it just calls them batteries)
