WHY IT NEEDS A POLICY

Why updateTask needs a policy

This tool modifies existing task data reversibly. It is categorized as Write rather than Read (it changes state) or Destructive (the change is reversible—tasks can be updated again). The severity is medium because unauthorized task updates could disrupt workflow planning or project tracking, but the blast radius is limited to task metadata rather than critical system operations or data deletion.

From the tool's definition Tool name 'updateTask' and description 'Update a task in Motion' indicate modification of existing data.
