Delete a single event by event_id. Returns {"deleted": 1} or {"deleted": 0}.
AI agents call delete_emotion_event to permanently remove resources in Jikan — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes individual emotion tracking events from the user's session history. While the blast radius is limited to a single event (not wholesale data destruction like delete_emotion_everything), deletion is non-reversible and represents data loss.
From the tool's definition Tool name is 'delete_emotion_event' with description 'Delete a single event by event_id.' The verb 'Delete' and the explicit function of removing data by ID indicate irreversible deletion of a data record.
