WHY IT NEEDS A POLICY

Why update_task_comment needs a policy

This tool creates or modifies data in a reversible manner. Updating a comment is a Write operation—the change can be undone by updating again or deleting. It does not execute code, delete data irreversibly, or move money. Medium severity reflects that misuse could modify task discussions in ways that confuse team collaboration, but changes are not permanent and can be corrected.

From the tool's definition Tool name is 'update_task_comment' and description states it 'updates comments' (指定したタスクのコメントを更新します = 'updates the comment of the specified task'). This modifies existing data reversibly.
