WHY IT NEEDS A POLICY

Why gbp_create_post needs a policy

This tool creates new content (posts) on a Google Business Profile, which is a reversible modification of business data. While posts can be deleted (gbp_delete_post exists), the act of creation itself is Write rather than Destructive. The impact is moderate since posts are business-facing but not financial transactions or system-critical data.

From the tool's definition Tool description states it can 'Create a new post on a GBP location' with text, media, and call-to-action buttons. The verb 'create' and 'new post' indicate data creation.
