WHAT IT DOES

What add_warp_pair does on Ice Puzzle

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

WHY IT NEEDS A POLICY

Why add_warp_pair needs a policy

This tool creates or adds new interactive elements (warp portals) to a game level, which is a reversible modification of level data. It does not execute arbitrary code, delete data, or move financial resources. The impact is scoped to level design and can be undone (similar to sibling tools like add_pushable_rock and add_thin_ice).

From the tool's definition Tool name 'add_warp_pair' and description 'Add a warp portal pair connecting two positions' indicate this creates new game elements within a level. The verb 'Add' and the context of level design tools on this server show this modifies level data.
