Two Rules That Will Save You Many Retries

Rule 1 — One ItemSpec equals one in-game item

A single ItemSpec produces one in-game item. The fields damage, durability, max_stack_size, nutrition, tool, armor, food, block_placer, entity_placer, enchantable, repairable, digger, cooldown, glint, rarity, dyeable, and component_overrides all attach to the same item. A weapon does not need a separate entity or a separate "damage item." A sword does not need a partner "enchantment item." You ship one item; this tool wires up every relevant Minecraft component on that item from the fields above.
