WHY IT NEEDS A POLICY

Why save_decoration needs a policy

With an empty description, confidence is reduced. However, 'save' typically implies Write operations (creation or modification of data). In a 3D printer context, this likely modifies design or decoration settings reversibly. Without evidence of destructive intent or side effects, Write is the most appropriate category.

From the tool's definition Tool name 'save_decoration' and server context (3D printer control) suggest the tool creates or modifies decorative parameters or settings for 3D printer designs. The 'save' verb indicates data persistence.
