 本轮要维护的聊天ID：{chat_id}
 本轮随机选中的起始记忆 ID：{start_memory_id}

+请优先以这条起始记忆为切入点，先理解它的内容与上下文，再决定如何在其附近进行创建新概括、重写或删除等整理操作；如果起始记忆为空，则由你自行选择合适的切入点。
 
 你可以使用的工具包括：
-- list_chat_histories：浏览该 chat_id 下的历史概括列表
+**ChatHistory 维护工具：**
+- search_chat_history：根据关键词或参与人搜索该 chat_id 下的历史记忆概括列表
 - get_chat_history_detail：查看某条概括的详细内容
-- merge_chat_histories：把多条内容高度相似或应当归为一类的记录合并到一条
+- create_chat_history：根据整理后的理解创建一条新的 ChatHistory 概括记录（主题、概括、关键词、关键信息等）
 - update_chat_history：在不改变事实的前提下重写或精炼主题、概括、关键词、关键信息
-- delete_chat_history：删除明显噪声、错误或无意义的记录（要格外谨慎）
-- finish_maintenance：当你认为当前 chat_id 下的维护工作已经完成，没有更多需要整理的内容时，调用此工具来结束本次运行
+- delete_chat_history：删除明显冗余、噪声、错误或无意义的记录，或者非常有时效性的信息，或者无太多有用信息的日常互动。
+你也可以先用 create_chat_history 创建一条新的综合概括，再对旧的冗余记录执行多次 delete_chat_history 来完成“合并”效果。
+
+**Jargon（黑话）维护工具（只读，禁止修改）：**
+- search_jargon：根据一个或多个关键词搜索Jargon 记录，通常是含义不明确的词条或者特殊的缩写
+
+**通用工具：**
+- finish_maintenance：当你认为当前维护工作已经完成，没有更多需要整理的内容时，调用此工具来结束本次运行
 
 **工作目标**：
 - 发现冗余、重复或高度相似的记录，并进行合并或删除；
 - 发现主题/概括过于含糊、啰嗦或缺少关键信息的记录，进行重写和精简；
+- summary要尽可能保持有用的信息；
 - 尽量保持信息的真实与可用性，不要凭空捏造事实。
 
+**合并准则**
+- 你可以新建一个记录，然后删除旧记录来实现合并。
+- 如果两个或多个记录的主题相似，内容是对主题不同方面的信息或讨论，且信息量较少，则可以合并为一条记录。
+- 如果两个记录冲突，可以根据逻辑保留一个或者进行整合，也可以采取更新的记录，删除旧的记录
+
