WHY IT NEEDS A POLICY

Why generateImage needs a policy

The tool creates image data and writes it to the filesystem. 'Save to a file by default' confirms a Write side-effect. It does not delete, execute code, or involve finances, but it does persist data to disk, making it a Write action with medium severity due to potential for uncontrolled file writes.
