dsh-companion-memory: local chat memory for DeepSeek Harness

Stores chat turns by origin (owner / group / private), retrieves them before each reply and hands them to the model as dated, untrusted evidence. Keyword retrieval works with no model; a local Ollama embedding model is picked up automatically; a chat model adds reranking and retrieval summaries. Licensed PolyForm Noncommercial 1.0.0.

1新增:# dsh-companion-memory
2新增:
3新增:给 DeepSeek Harness 里的鱼用的本地聊天记忆(源码公开,仅限非商用,见文末[许可证](#许可证))。它把聊过的原文存进本机 SQLite,回答前按「这段对话从哪来」检索相关历史,带着时间和场合交给模型;鱼也可以自己调用工具翻记忆、记一笔。
4新增:
5新增:**不绑定任何桥接。** 插件只用 DSH 官方接口(会话事件、`ctx.tools`、运行时上下文、web 服务)。不管消息是从 DSH 桌面端、官方 QQ 机器人、qq-bridge、AstrBot 还是别的什么进来,只要进了 DSH 会话就能记;各家的差别只体现在配置里,或者由桥接调用下面的开放接口。
6新增:
7新增:## 它解决什么
8新增:
9新增:| 问题 | 做法 |
10新增:| --- | --- |
11新增:| 桥接换会话 / `/reset` / 自动轮换后就失忆 | 记忆按**来源**(主人 / 群 / 私聊)存,不跟会话 ID 走 |
12新增:| 鱼靠 `send_message` 一类工具说话,助手正文是空的 | 这类工具的文字参数也算「她说的话」(可配置) |
13新增:| 桥接每次都塞一大段固定说明,检索被它淹没 | 跨轮重复出现的长行自动识别为套话,不入库、不参与检索;检索词按稀有度挑选 |
14新增:| 每一步都检索、往历史里追加一条消息 | 每条新的用户消息只检索一次,结果放进 DSH 运行时上下文:内容不变就不重发,变了只追加在已缓存历史之后,不破坏 KV 缓存前缀 |
15新增:| 私聊里的话被群友套出来 | 别人的私聊只在和他的私聊里可见;主人和群聊内容默认共享,可分别关闭 |
16新增:
17新增:## 记忆怎么工作(RAG)
18新增:
19新增:**存**:每一轮存一条原文,包括对方说的话、鱼通过读消息工具读到的别人的发言、鱼的回复(含通过发送工具说的话)。同一场合里重复读到的同一句话只存一次;桥接每次都会塞进来的固定说明不入库。
20新增:
21新增:**查**:每条新消息查一次,三处共用同一条检索路径:自动回忆、`chat_memory_search` 工具、`api/search`。
22新增:1. 关键词:中文按两字切词;某个字在查询里的两字组合都没被索引过时,才单独用这个字去匹配。只用查询里最有区分度的词,太常见的词(「什么」「今天」)自动去掉。
23新增:2. 向量(可选):配了 embedding 才启用,补上换了说法、没有共同字的情况。
24新增:3. 融合:两路按各自最高分归一后相加;候选中越新的最多加 15%,用来区分分数接近的新旧记录。
25新增:4. 前后文:命中的那一轮会带上同一场合里的前一轮和后一轮(6 小时内),「那就海边吧」这种才看得懂。
26新增:5. 给模型时按时间从早到晚排列,并说明「同一件事前后说法不同时,以较晚的为准」。
27新增:
28新增:**评测**:`npm run eval` 在一份模拟的 QQ 群聊和私聊语料上跑检索(加 `--embed bge-m3` 测向量模式),`npm test` 里有不得低于的下限。「答案在给模型的证据里」的比例:
29新增:
30新增:| 查询类型 | 只用关键词 | + nomic-embed-text | + bge-m3 |
31新增:| --- | --- | --- | --- |
32新增:| 原话 / 关键词 | 100% | 100% | 100% |
33新增:| 换说法 | 67% | 67% | 83% |
34新增:| 答案在下一轮 | 100% | 100% | 100% |
35新增:| 事实变过(搬家) | 100% | 100% | 100% |
36新增:| 夹在长提示里 | 0% | 0% | 0% |
37新增:| 完全没有共同字 | 0% | 0% | 50% |
38新增:| **合计(不含最后一类)** | **76%** | **76%** | **82%** |
39新增:| 排第一就命中 | 59% | 71% | 76% |
40新增:
41新增:`nomic-embed-text` 主要针对英文,对中文帮助有限;`bge-m3` 是中文首选。2 万条记录时,关键词检索中位数约 17ms。
42新增:
43新增:**聊天模型(可选):重排 + 检索摘要**。在重排里配一个聊天模型(协议 `chat`,任何 OpenAI 兼容接口都行;DeepSeek 会自动关闭推理以提速),它会同时做两件事:
44新增:
45新增:- **重排**:每次检索时,给最多 12 条候选打 0–10 分,判为无关的直接丢弃。它能推理隐含关系,比如「有什么不能吃的」对上「花生过敏」。
46新增:- **检索摘要**:在后台为每条记忆写一句摘要,把隐含的意思写明白,比如「去字节报到」写成「入职字节跳动公司,找到新工作」。攒够 10 条打包成一次请求。摘要**只用来检索**,命中后给模型的仍然是原文,所以摘要写错最多影响能不能找到,不会把编造的内容当成记忆。
47新增:
48新增:实测(19 条查询;DeepSeek `deepseek-flash` + 本机 bge-m3):
49新增:
50新增:| 配置 | 答案在证据里(不含语义题) | 语义题(无共同字) | 证据平均长度 | 每次检索耗时 |
51新增:| --- | --- | --- | --- | --- |
52新增:| 只用关键词 | 76% | 0% | — | 几毫秒 |
53新增:| + bge-m3 | 82% | 50% | 727 字 | 0.3 秒 |
54新增:| + 重排 + 摘要(不装 Ollama) | 82% | 50% | 371 字 | 0.9 秒 |
55新增:| + bge-m3 + 重排 | 100% | 50% | 442 字 | 1.0 秒 |
56新增:| **+ bge-m3 + 重排 + 摘要** | **100%** | **100%** | **485 字** | **1.1 秒** |
57新增:
58新增:成本(`deepseek-flash` 高峰价,非高峰减半):
59新增:- 摘要:每条记忆约 40 输入 + 14 输出 token,每 1000 条约 $0.03,只在入库时付一次。
60新增:- 重排:每次检索约 460 输入 + 28 输出 token,每 1000 次检索约 $0.17。
61新增:
62新增:模型出错或超时时,重排退回原来的检索顺序,摘要留到下次再补,记忆照常工作。配置时密钥只填**环境变量名**(如 `DEEPSEEK_API_KEY`),不要填密钥本身。
63新增:
64新增:评测命令:`DEEPSEEK_API_KEY=… npm run eval -- --embed bge-m3 --rerank deepseek-flash`。
65新增:
66新增:**零配置**:没配向量模型时,插件会检查本机 Ollama 有没有已经装好的中文向量模型(bge-m3、qwen3-embedding、multilingual-e5 等)。有就自动用上,并在后台给已有记忆补齐向量;只连本机,不下载、不外发。想装的话执行 `ollama pull bge-m3`(约 1.2GB)。
67新增:
68新增:**可以接别的模型吗**:聊天用哪个大模型由 DSH 决定,插件通过 DSH 的上下文接口提供记忆,换模型照样能用。向量和重排模型可以接本机 Ollama,或任何 OpenAI 兼容的向量接口(OpenAI、硅基流动、阿里百炼兼容模式等)、通用 `/rerank` 接口和 DashScope 重排;远程服务要求 HTTPS,并需要明确允许发送。
69新增:
70新增:## 来源怎么认
71新增:
72新增:按顺序:
73新增:
74新增:1. 桥接通过 `api/bind` 明确告诉插件某个会话属于哪个群 / 哪个人;
75新增:2. 按**会话 ID** 匹配规则(默认能认出 `group:123456`、`private:123456` 和 `xxx-g-123456-…` / `xxx-p-123456-…` 这类 ID);规则是纯数据,可在设置页改;
76新增:3. 都认不出来:默认单独隔离(只能看到自己);只有你一个人用 DSH 时可以设为「当作主人」。
77新增:
78新增:只读会话 ID,**不读消息内容**——群友可以在消息里随便写 `private:主人QQ`,会话 ID 他改不了。`ownerIds` 里的账号的私聊归入「主人」。
79新增:
80新增:可见范围:
81新增:
82新增:| 当前对话 | 能想起 |
83新增:| --- | --- |
84新增:| 主人的私聊 | 主人 + 所有群 |
85新增:| 某个群 | 这个群 + 其他群 + 主人 |
86新增:| 某人的私聊 | 和他的私聊 + 所有群 + 主人 |
87新增:| 认不出来源的会话 | 只有它自己 |
88新增:
89新增:「其他群」「主人」两项可以在设置页分别关掉。
90新增:
91新增:## 给模型的工具
92新增:
93新增:- `chat_memory_search`:按关键词翻以前聊过的原文。
94新增:- `chat_memory_note`:把约定、喜好这类值得长期记住的事写一笔。
95新增:- `chat_memory_forget`:按编号删除一条记忆,**只能删当前场合的**(防止群友让她删掉主人的记忆)。
96新增:
97新增:- `chat_memory_setup`:查看 / 修改记忆设置。用户不用懂配置,对鱼说「帮我把聊天记忆设置好,我的 QQ 是 ……」就行。修改**一律弹出 DSH 的批准**,而且只能在主人自己的对话里改,群里、别人的私聊里调用会被拒绝。
98新增:
99新增:工具声明固定不变,不影响缓存;前三个不需要时可以在设置页关掉。
100新增:
101新增:## 开放接口(给桥接或其他本机程序)
102新增:
103新增:只接受本机请求,请求头带 `Authorization: Bearer <令牌>`(令牌在设置页「桥接接口」里,也保存在数据目录的 `api-token` 文件中)。
104新增:
105新增:```http
106新增:POST /dsh-companion-memory/api/ingest {"origin":"group:123456","speaker":"小红","text":"我下个月搬去杭州","sourceKey":"msg-889","time":1762500000000}
107新增:POST /dsh-companion-memory/api/search {"origin":"private:10001","query":"搬家","limit":5}
108新增:POST /dsh-companion-memory/api/bind {"sessionId":"<DSH 会话 ID>","origin":"group:123456"}
109新增:```
110新增:
111新增:- `ingest`:桥接把它看到的群消息直接存进来(例如鱼潜水时没进 DSH 的群聊)。同一个 `sourceKey` 重复提交只存一次。
112新增:- `search`:按某个来源的可见范围检索,返回命中片段和一段可直接拼进提示词的 `evidence`。
113新增:- `bind`:会话 ID 认不出来源时,告诉插件它属于哪里。
114新增:
115新增:`origin` 取值:`owner`、`group:<号>`、`private:<号>`。
116新增:
117新增:## 模型接口(可选)
118新增:
119新增:默认不联网、不下载模型,用 FTS5 关键词检索就能工作。可以接 Ollama 或 OpenAI 兼容的 embedding,以及通用 `/rerank` 或 DashScope 重排。远程地址必须 HTTPS,并且要在设置里明确允许发送;密钥只从环境变量读取。
120新增:
121新增:## 安装
122新增:
123新增:普通 npm 包。用 DSH 插件管理器安装,并把 `cordis.patch.yml` 里的 bundle patch 应用到目标 profile(命令以你的 DSH 版本文档为准):
124新增:
125新增:```text
126新增:dsh plugin --profile desktop add <path-to-dsh-companion-memory>
127新增:```
128新增:
129新增:装好后在设置页填上**主人账号**;用 qq-bridge 这类会话 ID 里带群号的桥接,默认规则就能认出来源,其他桥接按上面「来源怎么认」配置。
130新增:
131新增:## CLI
132新增:
133新增:只处理你明确指定的 JSONL,不扫描 `.dsh` 历史。`export` 输出的 JSONL 可以直接 `import` 回去:
134新增:
135新增:```text
136新增:companion-memory import --dir ./data --file history.jsonl --scope owner
137新增:companion-memory search --dir ./data --query "之前的计划" --scope group:123456
138新增:companion-memory export --dir ./data --scope owner > owner.jsonl
139新增:companion-memory stats --dir ./data
140新增:```
141新增:
142新增:删除记忆会删掉原文、索引并留下墓碑,防止被自动重新导入;它不会抹除 DSH 自己的会话日志、WAL 或备份。
143新增:
144新增:## 测试
145新增:
146新增:```text
147新增:npm test # 单元测试 + 检索质量下限
148新增:npm run eval # 打印检索评测报告(只用关键词)
149新增:npm run eval -- --embed bge-m3 # 加本机 Ollama 向量
150新增:DEEPSEEK_API_KEY=… npm run eval -- --embed bge-m3 --rerank deepseek-flash # 再加重排和检索摘要
151新增:```
152新增:
