WHY IT NEEDS A POLICY

Why create_sprite_atlas needs a policy

This tool creates a new asset artifact (a sprite atlas file), which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could generate unwanted asset files that clutter projects or consume storage, but the impact is bounded to asset generation and not destructive.

From the tool's definition Tool named 'create_sprite_atlas' on a server that generates 2D game assets and exports to Unity. The sibling tools (batch_generate, generate_character, export_to_unity, etc.) all perform asset creation. Creating a sprite atlas creates/modifies asset files.
