WHY IT NEEDS A POLICY

Why update_image_metadata needs a policy

The tool name strongly suggests it modifies metadata associated with image files, which constitutes reversible data modification (Write category). Metadata updates are not destructive—they can be undone or re-modified. The empty description prevents higher confidence, but the name is sufficiently clear that this is a modification operation rather than read-only (Read) or execution (Execute).

From the tool's definition Tool name 'update_image_metadata' indicates modification of image file metadata. Server context describes 'file operations' and 'write' capabilities for Windows system management. Empty description limits certainty.
