@plur-ai/dsh

Persistent memory for DeepSeek Harness. Your agent corrected on Monday remembers on Tuesday.

English | 中文

Source lives in the PLUR monorepo. This repository is the plugin's public entry point — the npm package is built and published from the monorepo. Open issues and pull requests there.

Exposing memory as a tool is the common pattern — the model still has to decide to call it. This one puts the memories themselves in the prompt.

Overview

DeepSeek Harness starts every session knowing nothing about you. You re-explain the same conventions, corrections and preferences you explained yesterday.

This plugin gives dsh a memory that survives the session: corrections you make once, project conventions, the decisions behind them. It is for anyone who uses dsh for real work in the same codebase more than once.

Everything stays on your machine as plain YAML you can read, edit and delete.

Compatibility

DeepSeek Harness	0.1.0-rc.6 and later on the 0.1.x line (^0.1.0-rc.6)
Cordis	^4.0.1
Node	20, 22, 24, 26 (tested in CI on all four)
Last verified against	dsh 0.1.0-rc.6, 2026-08-15

The dsh line is pre-1.0 and moving. Peer ranges use a caret so this plugin keeps installing as the line advances; if a future release changes a host contract, the plugin degrades to "no memory" rather than breaking your agent — every host registration is contained, and /plur will show the failure.

Install

dsh plugin --profile web add @plur-ai/dsh

That's it. Restart dsh and your agent has memory.

Requires @plur-ai/core, which installs alongside it.

Quick start

Teach it something once:

You: Always use pnpm in this project — npm install breaks the lockfile in CI.

Nothing else to do; the correction is detected and stored. Start a new session tomorrow, in the same directory:

You: How do I install dependencies here?

Agent: Use pnpm install — you mentioned npm breaks the lockfile in CI.

No reminder, no tool call. To see what it knows, run /plur-memory.

Uninstall

dsh plugin --profile web remove @plur-ai/dsh

Your memories are not touched — they live in ~/.plur, independently of this plugin, and remain available to every other PLUR integration. To remove them too, delete that directory; to remove one engram, use plur_forget or @plur-ai/cli.

To disable without uninstalling, set injectionMode: off (below).

How it works

PLUR registers a system-prompt section that DeepSeek Harness re-renders on every request. Relevant memories are simply there, in front of the model, with no tool call to decide on.

Recall runs off the turn path, so the block lands from the second assembly of a session onward. A turn is never delayed waiting on the memory store.

Extra round trip per recall	Yes	No
