WHY IT NEEDS A POLICY

Why photoshop_resize_image needs a policy

Resizing an image modifies its properties and pixel data, making it a Write operation rather than Read (which would only query state). It is not Destructive because resizing is reversible and does not irreversibly delete data. Severity is medium because misuse could corrupt or degrade image quality, but the operation is contained to a single document and reversible.

From the tool's definition The tool 'photoshop_resize_image' with description 'Resize the active image to specified dimensions' modifies image data by changing its dimensions. This is a reversible modification (via undo or subsequent resizing) that alters the document state.
