WHY IT NEEDS A POLICY

Why workitem.comment needs a policy

This tool creates new comment data on a work item, which is a reversible write operation. It does not delete or overwrite existing data, execute code, or involve financial transactions. Misuse could post unwanted comments to work items, but effects are limited in blast radius and reversible by deleting the comment.
