WHY IT NEEDS A POLICY

Why update_space needs a policy

This tool creates or modifies data in a reversible manner (name, description, privacy settings can all be changed back), fitting the Write category. Severity is medium because updating a space could affect visibility/access for multiple users, but the changes are not destructive and can be undone. Confidence is high given the clear, explicit description of update operations.

From the tool's definition Tool description states it 'Updates an existing space' with modifications to 'name, description, and/or privacy' — core write operations that modify existing data reversibly.
