flymysql/dsh-memory

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
