WHY IT NEEDS A POLICY

Why generate_image_gpt needs a policy

However, it is not Destructive (no deletion), Financial (no money movement), or Execute (no arbitrary code execution—parameters are constrained to image generation settings like size and quality).

From the tool's definition Tool name 'generate_image_gpt' and server description states it 'allows users to create and save images'. The description explicitly mentions image generation and saving, which are write operations that create new data artifacts.
