WHY IT NEEDS A POLICY

Why gbp_reply_review needs a policy

This tool posts a reply to a customer review on the business's Google Business Profile. It creates/modifies data (the review reply) but is reversible since there is a sibling tool gbp_delete_review_reply that can undo it. Misuse could cause reputational harm by posting inappropriate responses publicly on behalf of the business, warranting a medium severity rating.

From the tool's definition 'Reply to a review on behalf of the business' — creates a new reply, which is a reversible write action
