WHAT IT DOES

What scan_unity_asset_store_cache does on Assetcache

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

WHY IT NEEDS A POLICY

Why scan_unity_asset_store_cache needs a policy

The tool reads the Unity Asset Store cache directory but its primary effect is writing/updating records in a database (synchronization). This is a reversible write operation with medium severity since it modifies DB state but does not delete data or execute arbitrary code.

From the tool's definition '스캔해 .unitypackage 목록을 DB 에 동기화한다' — scans cache directory and synchronizes (writes/updates) the list of .unitypackage files into the database
