dsh-memory-echo

原话级短期记忆插件,用于 DeepSeek Harness。

长期记忆库保留的是提炼后的结论;本插件保留真正说过的话,用于回答"我上次说过什么"这类需要逐字原文的问题。它不自动注入上下文,只在被查询时取用。


Utterance-level short-term memory for DeepSeek Harness.

A long-term memory store keeps distilled conclusions. This plugin keeps what was actually said, so questions like "what did I say last time" can be answered from verbatim text. It never injects into the context automatically; it is read only on demand.

安装 / Install

dsh plugin add dsh-memory-echo

或从源码安装 / or from source:

git clone https://github.com/CNyaotian-Lunar/dsh-memory-echo.git
cd dsh-memory-echo
npm install && npm run build
dsh plugin add link:$(pwd)

它读什么、写什么 / What it reads and writes

读取 Reads $DSH_HOME/sessions/**/session.v4.jsonl.zstd —— 你的会话日志 / your session logs
只取 Keeps only 你自己发的消息(source.kind === 'user');不取助手回复、工具输出、子代理任务书 / your own messages only
写入 Writes $DSH_HOME/data/dsh-memory-echo/echo.db(SQLite,全局一份 / one global DB);想换位置就设 dbDir
网络 Network 无。插件不发任何请求 / none

隐私 / Privacy

这是一个本地插件,但它确实会把你说过的话复制一份到本地 SQLite。三件事你需要知道。

This is a local plugin, but it does copy what you said into a local SQLite file. Three things you should know.

  1. 写入前脱敏 / Redaction before writing 落库前会替换掉可能被直接使用的凭据:sk- 密钥、JWT、Authorization / Cookie 头、查询串里的 token= / sig= / X-Amz-Signature=、password=、常见会话 cookie(SESSDATA、__cf_bm、jsessionid 等)、以及 32 位以上 hex / 40 位以上 base64 长串。替换是只换值、保留键名与上下文,所以你仍看得出"当时在配一个 token"。 Credentials are replaced before the row is written, keeping the key name and surrounding context.

    ⚠️ 这不是万无一失:脱敏是按模式匹配的,模式没覆盖到的形态会原样入库。若你曾把密钥粘进对话,请视为已落盘。 ⚠️ Not a guarantee: redaction is pattern-based. Anything not matching a pattern is stored verbatim.

  2. 默认会淡出 / Fades by default 每条原话带一个 valid_until(默认 30 天,retentionDays: 0 可关闭)。到期后默认查询看不到,但数据仍在库里 —— 带 includeExpired: true 依然能取回。 Rows carry a valid_until (30 days by default; set retentionDays: 0 to disable). Expired rows disappear from normal queries but remain on disk; includeExpired: true still returns them.

  3. 怎么删 / How to delete 关掉插件后直接删这个目录即可,插件不会重建它以外的任何东西。 Disable the plugin, then delete that directory. Nothing else is created.

    删除 / delete: $DSH_HOME/data/dsh-memory-echo/
    

配置 / Configuration

键 Key 默认 Default 说明
enabled true 关掉后不注册工具、不扫描 / disables everything
dbDir '' 库所在完整目录;空 = $DSH_HOME/data/dsh-memory-echo。⚠️ 库是全局一份,不按工作区分 —— 这层存的是「你说过的话」,换个工作区不改变你是谁
sessionsRoot '' 会话日志根;空 = $DSH_HOME/sessions
autoScan true 加载时做一次增量扫描 / incremental scan on load
autoScanDays 7 增量扫描回看几天

用法 / Usage

工具名 memory_echo。

memory_echo({ query: "硬盘" })                      // 查关键词
memory_echo({ days: 1 })                            // 今天说过什么
memory_echo({ mode: "bucket", days: 1 })            // 按天聚合:哪一段、几条、样例
memory_echo({ query: "方案", includeExpired: true }) // 连已淡出的一起查

🩸 query 必须是 2~4 个字的实体词(硬盘、报错、深色),不要传整句。整句会被切成多个片段、要求每个都命中,反而一条都查不到 —— 想查"我上次说的那个方案",就传 方案。

🩸 query must be a 2–4 character concrete term. A full sentence is split into fragments and each must match, so it usually matches nothing. To look up "that plan I mentioned", pass 方案.

设计约束 / Design constraints

约束 原因
存全文,不做有损压缩 压缩会丢动词与否定词 —— 把「别点它,会连坐杀掉后台任务」压成「连坐杀掉后台任务」,意思就从禁令变成了操作步骤
不自动注入 执行途中不会停下来查询,预置反而抑制查询
查询失败必须区分原因 not-found / unavailable / empty-db / expired 四种含义不同。「取不到」不等于「没说过」
只存用户发言 助手回复与工具输出不是"说过的话"

状态 / Status

0.1.x —— 接口与数据格式尚未稳定。运行时的依赖为零(只用 node: 内置模块)。

0.1.x — interfaces and data format are not yet stable. Zero runtime dependencies (only node: built-ins).
