WHY IT NEEDS A POLICY

Why discord_edit_message needs a policy

This tool modifies existing data (Discord messages) reversibly. It does not delete data (which would be Destructive), nor does it execute arbitrary code or perform financial operations. The modification is reversible via subsequent edits. Severity is medium because while message edits could be misused to alter communication history, the action is limited to messages sent by the webhook and is not irreversible.

From the tool's definition Tool description states it 'edits' messages (discord_edit_message) sent via webhook. The function modifies existing Discord messages by updating content and/or embeds, which is a reversible data modification operation.
