Fields

Field	Type	Required	Default	Description
type	enum	Yes	—	One of resourcefulbees:spawns, resourcefulbees:dev_spawns, or resourcefulbees:supporter_spawns.
whitelist	biome holder set	Yes	—	Biomes in which this spawn may be added.
blacklist	biome holder set	No	[]	Biomes excluded from spawning. The default empty holder set excludes no biomes.
spawn	spawn	Yes	—	Flattened weighted SpawnerData. Requires entity type, minCount >= 1, maxCount >= 1, and weight >= 0; runtime additionally requires minCount <= maxCount.
spawnPredicate	locationPredicate	No	—	Optional Minecraft LocationPredicate restricting where the spawn may occur.

whitelist and blacklist are each one biome holder set. See Holder Sets for the accepted single-ID, tag, compact-array, and NeoForge custom-object representations.

Runtime notes

The modifier runs during the biome modifier ADD phase. A biome must match the whitelist holder set and must not match the blacklist holder set. resourcefulbees:dev_spawns and resourcefulbees:supporter_spawns are additionally gated by their respective configuration options.

spawn.minCount must be less than or equal to spawn.maxCount. This is codec validation that Draft 2020-12 JSON Schema cannot express as a direct comparison between sibling properties.
