dsh-deja
DeepSeek Harness 的 deja-vu 记忆：三十二个其他编码代理的会话历史，可搜索并在每一步之前召回——本地索引，无需 LLM。
插件会安装到这里；不确定时保持 web。
npx -y @deepseek-ai/dsh plugin --profile web add dsh-deja@0.20.9
Deja 以 dsh-deja 发布，当前版本为 0.20.9。Plugin Hub 会校验它的 manifest，并保存精确安装来源，便于复现安装结果。

DeepSeek Harness can already search its own sessions — that is what the built-in
session-query subsystem does. This plugin answers the other question: what you
did in the other agents on this machine.
deja indexes the session files that thirty-two other coding agents — Claude Code, Codex, Cursor, opencode, Antigravity, Grok Build, Kimi, Cline and Zed among them — already write to disk. Nothing has to have been recorded ahead of time: the history is already there, including the months before deja was installed. If you moved to dsh last week, everything you did before last week is still reachable from inside it.
dsh plugin --profile web add dsh-deja
From the repository instead of npm — the root manifest re-exports this directory, so either form works:
dsh plugin --profile web add github:vshulcz/deja-vu#path:extensions/dsh
The plugin runs the deja binary. It is pulled in as a dependency, so npm
installs it with the plugin; a deja already on PATH is used as-is, and
DEJA_BIN overrides both.
If you have the CLI, deja install --auto wires dsh too — it adds deja's MCP
server and a /deja command to your profile — and that is the shorter path.
Having both is fine: this plugin looks for what the installer wrote in
$DSH_HOME/plugins/deja/ and contributes only what is missing, so the tools and
the command are never registered twice.
Six tools the model can call:
| Tool | Answers |
|---|---|
deja_recall | Sessions matching an error string, function name, file path or flag. |
deja_session | The full digest of one past session, when the reasoning behind it matters. |
deja_blame | The sessions that discussed a file, before you edit or delete it. |
deja_fix | What this machine ran after that same error before. |
deja_how | The real invocation for a build, test or deploy, from what ran here. |
deja_remember | Stores one settled decision for later recall. |
One command: /deja <what to look for>.
And, unless you turn it off, automatic recall: before each step the plugin asks deja whether this machine's history answers the prompt, and adds the answer to the runtime context. Silence is the common case — it speaks only when there is something to say.
- insert:
- id: deja
name: dsh-deja
config:
autoRecall: false # tools and /deja only
Recall arrives through ctx.systemPrompt.context, evaluated on every assembly.
The obvious alternative — a middleware on agent/pre-step that splices a
message into the step — loads fine, completes the turn, and never reaches the
model: a later listener in that waterfall rebuilds its answer from the payload
and the added message is dropped with nothing reported. This was settled by
reading the requests dsh 0.1.1-rc.2 actually sent.
No LLM, no embeddings, no network. The index is a local BM25 store over files that already exist, so a query answers in about a millisecond and nothing leaves the machine. Secrets are redacted at index time.
