WHY IT NEEDS A POLICY

Why generate-image needs a policy

This tool generates or edits images using the Volcengine Ark API. It creates new content (images) or modifies existing ones, which is a Write operation. It does not execute code, delete data, or involve financial transactions. Severity is medium as it involves API calls that may incur costs and produce content, but has limited blast radius.
