Minecraft:Loot context

A loot context is a set of parameters available to Minecraft:loot tables, Minecraft:predicates, Minecraft:item modifiers, Minecraft:number providers, and Minecraft:slot sources.

When evaluating these data types in different situations, different parameters will be available. For example, a loot table that runs when the player mines a block would get a tool parameter if the player used an item to do it, but a loot table that populates a treasure chest would never get a tool parameter. Loot contexts are Minecraft:identifiers describing which parameters are available in specific situations. If one is set as the Template:Nbt of a loot table, it can be used to check whether the loot table depends on parameters that will never be available in its intended use case, allowing the game to report a problem when the Minecraft:data pack is loaded.
