Delete a custom emoji from a server
AI agents call delete_emoji 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.
This tool permanently removes a custom emoji resource from a Discord server, which cannot be undone programmatically. While the blast radius is limited to emoji assets rather than user data or messages, the destructive nature of the operation and potential to disrupt server appearance/branding justifies 'Destructive' categorization over 'Write'.
From the tool's definition Tool name 'delete_emoji' and description 'Delete a custom emoji from a server' - the verb 'Delete' combined with the irreversible nature of removing a server emoji indicates destructive action.
