What it does
Cross-session memory for the model: full-text search all past sessions (SQLite FTS5 via ctx.sessionQuery) and bring the strongest matching excerpts back into the current context.
Best for
- Users who want new sessions to recover decisions, commands, or mistakes from earlier DSH conversations.
- Agents that need full-text discovery across persisted sessions before continuing prior work.
- Workflows that benefit from retrieving a few strong matching excerpts and then opening exact sessions separately when needed.
Not ideal for
- Profiles without ctx.sessionQuery or with full-text search disabled by openAt: never.
- Exact archival retrieval, because results are FTS5 excerpts rather than complete session playback.
- Substring searches that do not align with the unicode61 tokenizer's token boundaries.
- Users who need history from other machines or deployments; recall only searches the current DSH_HOME.
README
dsh-plugin-recall
DeepSeek Harness 插件:给模型跨会话记忆 —— 全文检索所有历史会话,把最强匹配片段带回当前上下文。
背景
DSH 已经把每个会话持久化,并用 SQLite FTS5 建了全文索引(ctx.sessionQuery.searchSessions),但没有任何面向模型的工具去读它 —— 新会话对旧会话的决策、命令、踩过的坑一无所知。recall 把这个现成索引变成模型的能力:开新会话先 recall 一下,接着上次的进度继续。
使用
模型工具 recall:
recall query: "we decided to use sqlite" # 默认返回最多 5 个会话
recall query: "publish script" limit: 3
recall query: "权限绕过" sessionIds: ["s_xxx"] # 限定会话范围
返回每个命中会话:session id、时间、事件类型、live/persisted 标记、最强匹配片段。查询按字面短语处理(永不解释为 FTS 可执行语法)。
人类命令 /recall <查询>: 同样输出。
安装
dsh plugin --profile web add dsh-plugin-recall
挂载(标准 web profile 已含 dsh-session-query-sqlite,无需额外配置):
- insert:
- id: recall
name: dsh-plugin-recall
设计说明
-
复用官方基建:直接调用
ctx.sessionQuery.searchSessions(SQLite FTS5),不改任何官方包;sessionQuery未挂载时工具给出明确提示,而不是让组合加载失败。 -
纯逻辑可单测:参数校验 / 请求构建 / 命中映射 / 渲染在
lib/recall.js,npm test零依赖。 - 只拷贝叶字段:命中结果从 live 服务对象提取为纯 JSON(sessionId / time / type / snippet),绝不引用内部对象。
诚实边界
- 依赖
ctx.sessionQuery存在;openAt: never配置下全文检索被禁用时,recall会报错提示。 - 命中片段是 FTS5 的高亮摘录(unicode61 分词器,
AI匹配不到 tokenBRAID这类子串),不是精确回溯;需要精确读取请配合 session 工具。 - 检索范围为当前 DSH_HOME 的持久化会话语料,不含其他机器/部署的历史。

Frequently Asked QuestionsFAQ
Use the verified command dsh plugin --profile default add github:truelove-dreamer/dsh-plugin-recall in a DSH-enabled shell. The command resolves the public package metadata and keeps the plugin attached to the catalog identity shown on this page.
Compatibility follows the bundle and profile status shown above. If a profile is not detected, keep the plugin disabled there and check the repository documentation before enabling it in production.
