Destructive action

An action that deletes data or undoes work in a way that can’t be trivially reversed — delete, overwrite, revoke, leave-without-saving.

Example usage
Style ‘Remove all collaborators’ as a destructive action — red label, separated from the safe options.
Editor’s note

The red label is convention, but placement matters more: never put a destructive action where muscle memory expects a safe one. And the strongest protection isn’t a confirmation — confirmations train users to click through. Undo forgives them after the fact, which is the only moment they’re paying attention.
