All this acts as normal trait stuff, so they go in trait.json.

{
  "code": "exampletrait",
  "AllowedItems": ["game:spear-generic-iron"], // Allows usage of the iron spear even if it's later disallowed
  "DisallowedItems": ["game:spear-*"], // Blocks both attacking and throwing of all spears. Disallows both attack and interaction.
  "DisallowedAttack": ["game:blade-falx-copper-*" ], // Blocks attacking only
  "DisallowedInteract": ["game:bow-*", "game:bread-*" ], // Blocks use interaction only (includes eating the item). This makes the bow unusable and the bread inedible
  "DisallowedAsIngredient": ["game:fruit-cloudberry" ], // Blocks eating the item and eating any meal or pie that contain the item
  "ExclusiveItems": ["game:spear-generic-ornategold"], // Only classes that have this trait can use this item
  "AllowedWearables": ["game:armor-*-tailored-*"], // Allows wearing all variants and parts of the linen armor, even if later disallowed by wildcards
  "DisallowedWearables": ["type:armor", "game:clothes-nadiya-*"], // Blocks wearing all armors and the nadiya clothing. Available types: type:all, type:armor, type:clothing
  "ExclusiveWearables": ["game:armor-body-antique-forlorn-*"] // Makes forlorn hope armor exclusive to owners of this trait only
  "AllowedFood": {
    "game:fruit-*": { "Health": 2 }, // Overrides fruit to give health, leaves satiety and food category untouched
    "game:redmeat-raw-*": { "Satiety": 200, "FoodCategory": "Protein" }, // Makes raw meat edible
    "game:charcoal": {} // Makes charcoal edible, but gives no nutrition
  }
