WHAT IT DOES

What unequip_item does on DM20 Protocol

AI agents use unequip_item to create or update resources in DM20 Protocol — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DM20 Protocol environment.

WHY IT NEEDS A POLICY

Why unequip_item needs a policy

Based on the tool name, this likely modifies a character's equipment state by unequipping an item — a reversible write operation. The empty description lowers confidence significantly. Given the server context (D&D campaign management), this is a low-severity state change on a game character sheet with no real-world impact.

From the tool's definition Tool name 'unequip_item' suggests removing an item from equipped status on a character sheet. Description is empty and uninformative.
