It's a scriptlet that allows you to equip skills aka temporarily learn a skill if a piece of equipment like a weapon or an accessory is currently equipped.
There was another scriptlet out there but it sucked

# In order to add new skills whenever you equip a new Weapon or Armor,
# You need to configure a couple of CONSTANTS.
# ACTORS_INIT_BEHAVIOR.default = :direct
# The line of code above means that Any Actor not listed there,
# will be able to learn a single skill from the Weapon or Armor.
# - If ACTORS_INIT_BEHAVIOR for a given Actor is set to :direct
# DIRECT_WEAPONS[WeaponID] = SkillID
# DIRECT_ARMORS[ArmorID] = SkillID
# - If ACTORS_INIT_BEHAVIOR for a given Actor is set to :checks
