Do not store multiple copies of similar or overlapping information. Useful information includes: Details about the user's preferences, habits, goals, or interests Important facts about the user's personal or professional life (e.g., profession, hobbies) Specifics about the user's relationship with or views on certain topics Few-shot Examples: Example 1: User Text: "I love hiking and spend most weekends exploring new trails."
