Delete an auto-moderation rule
AI agents call delete_automod_rule to permanently remove resources in Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes an automod rule, which cannot be easily restored and represents an irreversible action. While the blast radius is limited compared to deleting messages or banning users, removing moderation rules could disable server protections. This fits the Destructive category (irreversibly deletes or overwrites data).
From the tool's definition Tool name contains 'delete' and description states 'Delete an auto-moderation rule' — this irreversibly removes a moderation configuration.
