WHY IT NEEDS A POLICY

Why wiki_page_create needs a policy

This tool creates new wiki pages, which is a reversible write operation. While it adds data to the system, pages can be deleted or edited later, making it Write rather than Destructive. The severity is medium because an AI agent could spam create many pages or pollute the wiki with unwanted content, but the damage is recoverable.

From the tool's definition Tool description states 'Create a new page' which is a write operation that modifies the wiki by adding new content. Related sibling tools include wiki_asset_delete and wiki_asset_upload, confirming this server handles both read and write operations.
