+- 客观准确：只记录实际发生的事件，不添加主观推测或情感评价
+- 结构清晰：按时间顺序提取关键节点
+- 忠于原文：尽量保留原始表述，避免过度概括
+- 重点突出：只记录推动事件发展的关键信息
+
+【记录要点】
+- 关系状态的实际变化（约定、承诺、矛盾、和解等具体事件）
+- 重要的对话内容和决定
+- 人物之间的互动行为
+- 情感表达的关键时刻
+
+【输出格式要求】
+- 只输出一个JSON对象
+- 不要使用markdown代码块
+- 直接以 { 开头，以 } 结尾
+- keys: 3-5个能代表本次聊天核心内容的关键词
+- content: 按"序号: 事件记录"格式列出关键节点（每条一行）
+- comment: "${getCupName(cupNumber)}"
