WHY IT NEEDS A POLICY

Why manage_pending_reply needs a policy

This tool performs a write operation by changing the moderation state of content. It is reversible (can be undone by changing the approval state again) and does not permanently delete data or commit financial transactions, so it falls under Write rather than Destructive or Financial.

From the tool's definition Tool description states 'Approve or ignore a pending Threads reply' — this modifies the state of a reply by changing it from pending to approved or ignored, which is a reversible state change.
