WHY IT NEEDS A POLICY

Why create_page needs a policy

This tool creates new content (pages) in a Ghost CMS instance, which is a reversible write operation. It modifies the CMS state by adding new data. While not destructive (can be undone by deletion) or financial, and not code execution, it clearly falls under Write category.

From the tool's definition Tool name 'create_page' and description indicating creation of new pages ('新しいページを作成' = 'create new page'). Server context confirms this integrates with Ghost Admin API for content management.
