## Why spine_create_loading_animation_preset is rated Medium

This tool creates and modifies animation preset data by writing JSON and manifest files. It is a Write operation because it creates or modifies data reversibly—the animation presets can be edited, deleted, or regenerated without permanently damaging underlying project integrity.

From the tool's own definition: "Tool description states 'Create a loading animation preset on a Spine JSON copy' and 'Writes JSON + manifest only,' explicitly indicating creation and modification of data files."

## Use case

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