Many of the lists are ordinary item, block or entity tags, all under the chiikawa namespace:

Tag	Type	What it controls
entity_tame_foods	Item	Foods that can be used for taming
currency	Item	The mod's money, emeralds by default
pet_treats	Item	The food Rakko takes out of its backpack when it treats someone
entity_farmer_tools	Item	Held in hand, makes a Farmer; all hoes by default
entity_fencer_tools	Item	Held in hand, makes a Fencer; all swords and the characters' weapons by default
entity_archer_tools	Item	Held in hand, makes an Archer; bows by default
entity_musician_tools	Item	Held in hand, makes a Musician; the Music Box by default
entity_harvest_crops	Block	Crops that Farmers harvest
entity_plant_crops	Item	Seeds that Farmers plant
entity_weeds	Block	Blocks that count as weeds and get pulled up
entity_mushrooms	Block	Mushrooms that Farmers pick at night
entity_pickable_items	Item	Things Farmers pick up off the ground
entity_deliver_items	Item	Harvest that Farmers put into chests
entity_delever_container	Block	Containers Farmers put their harvest into (yes, the id really is spelled that way)
entity_hostile_entity	Entity	Mobs that Fencers and Archers attack

For example, to let pets farm with a hoe from another mod in your modpack, just add an entry to entity_farmer_tools:

{
  "replace": false,
  "values": ["examplemod:copper_hoe"]
}

Once you change currency, slip pay, Shop prices and the cost of upgrading the Labor Board all switch to the new currency.
