WHY IT NEEDS A POLICY

Why add_pull_request_review_comment needs a policy

This tool creates or appends review comments to pull requests, which are reversible modifications to repository data. While it could be misused to spam, post misleading code review feedback, or inject malicious commentary that delays legitimate development work, these effects are non-destructive and can be undone by deleting the comment.
