WHY IT NEEDS A POLICY

Why wikijs_update_page needs a policy

This tool creates or modifies data in a reversible manner. While it can change wiki page content, the changes are not irreversible—previous versions can be recovered via the versioning system mentioned in the server description ('page versioning'). The safety gates (WIKI_MUTATIONS_ENABLED flag and optional confirmation token) further confirm this is categorized as Write rather than Execute or Destructive.

From the tool's definition Tool name contains 'update' and description explicitly states 'Update an existing page by ID', which modifies existing data reversibly.
