WHY IT NEEDS A POLICY

Why create_wiki_page needs a policy

Creating wiki pages is a reversible write operation that modifies the knowledge base. While not destructive, it can introduce unwanted content or misinformation if misused by an agent. Severity is medium because: (1) effects are reversible via deletion, (2) typical wiki permissions may limit who can create pages, and (3) impact is informational rather than directly harmful.

From the tool's definition Tool name 'create_wiki_page' indicates page creation. Server description states it 'support[s] operations like page creation...'. Tool description is empty but context from sibling tools and server purpose clarifies the function.
