What it does

Cross-session memory vault: remember / recall / forget tools, per-turn prompt injection, and a settings-page entry browser.

Best for

  • Users who want facts, preferences, decisions, and project notes to persist across DSH sessions.
  • Agents that benefit from recent memory entries being injected into every turn automatically.
  • Users who want explicit remember, search, and deletion controls through model tools.
  • Users who want to browse, add, and remove stored entries from DSH Settings.

Not ideal for

  • Stateless or privacy-sensitive workflows that should not retain information across sessions.
  • Workflows where automatically injecting recent entries into every turn would add irrelevant context.
  • Users who need semantic vector search rather than the documented tag/content matching and recency ordering.
  • Environments that cannot use the DSH storage domain and same-origin web endpoints.

README

dsh-memory-vault

Cross-session memory vault for DeepSeek Harness (DSH).

Every DSH session starts from zero. dsh-memory gives your agents a persistent second brain: facts, preferences, decisions, and project notes survive across sessions and are recalled automatically.

  • 3 model tools — memory_remember / memory_recall / memory_forget
  • Per-turn prompt injection — the most recent entries are injected into every system-prompt assembly, so the agent starts each turn already aware of stored context
  • Durable storage — records live in a storage domain (dsh_memory unit, json backend by default; unit names are snake_case per UNIT_NAME_RE)
  • Browser management page — a “记忆库 / Memory” page in Settings to browse, add, and delete entries

Install

dsh plugin --profile web add dsh-memory-vault

The dsh.bundle manifest wires the dsh-memory row into the profile automatically. To install by hand instead:

npm install dsh-memory-vault

then add a row to your profile cordis.yml (or cordis.patch.yml):

- id: dsh-memory
  name: dsh-memory-vault

Usage

Tell your agent to remember things, or do it yourself:

“记住：这个项目的部署目标是 Windows，测试命令是 pnpm test。”

The agent calls memory_remember with optional tags:

memory_remember(content="User prefers Windows deployment; test command is `pnpm test`", tags=["project:demo", "user"])

When context from an earlier session matters, the agent calls memory_recall(query="Windows deploy") — entries are scored by tag matches (×2) and content matches, newest first. Wrong or obsolete facts are removed with memory_forget(id="m-...") or memory_forget(tag="project:demo").

Configuration
Key Type Default Meaning
injectLimit int 8 Max entries injected per system-prompt assembly
recallLimit int 10 Max entries returned by memory_recall 
- id: dsh-memory
  name: dsh-memory-vault
  config:
    injectLimit: 12
    recallLimit: 20

Browser page

Settings → 记忆库 (Memory). Lists all entries newest-first with tags and timestamps; quick-add and delete buttons.

The page talks to the host half through the harness webServer service — same-origin JSON endpoints (GET/POST /dsh-memory/entries). The dynamic-plugin prototype used the sandbox-only harness.handle/host.call package RPC; the published package uses the public route so it works in any deployment.

Development

The plugin is one cordis package:

  • lib/index.js — host half: domain, tools, prompt injection, RPC handlers
  • lib/client.js — web half: settings page
