WHAT IT DOES

What aseprite_export does on Aseprite

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

WHY IT NEEDS A POLICY

Why aseprite_export needs a policy

The aseprite_export tool creates new image files in different formats (PNG, GIF, sheet, data) from existing Aseprite files. This is a Write operation because it produces new output files that persist on disk, modifying the filesystem state.

From the tool's definition Tool description states 'Export an existing Aseprite file/image to PNG/GIF/sheet/data using common CLI flags.' Export operations create new files in alternative formats, which is a data creation/transformation action.
