Overview

dsh-memory-connect is a cross-session memory sharing plugin for DeepSeek Harness. It automatically extracts, stores, and recalls memories across sessions, giving your AI agent persistent, intelligent memory with context explosion prevention and global Soul identity.

Zero-config — works out of the box with SQLite FTS5 and DSH's built-in LLM.

Features

Feature	Description
🧠 Global Soul	Persistent identity across all workspaces via ~/.dsh/soul.md
🔍 Auto Extraction	Extracts facts, preferences, decisions, and context from conversations
🧠 Semantic Recall	RRF (Reciprocal Rank Fusion) combines keyword and semantic search
🛡️ Context Explosion Prevention	Token budget management prevents context window overflow
⏰ Scheduled Maintenance	Automatic periodic decay and consolidation via built-in scheduler
🤖 LLM Consolidation	Intelligent memory merging using DSH's built-in ctx.llm (zero-config)
📉 Memory Decay	Old, unused memories naturally fade; frequently accessed ones persist
🎯 Smart Prioritization	Memory selection based on relevance × recency × frequency
🗜️ Memory Compression	Automatic compression when approaching token limits

🧠 Global Soul (Identity)

The Soul feature provides a persistent identity that follows you across all workspaces.

How it works

1. Create ~/.dsh/soul.md with your identity information
2. The plugin automatically loads and injects it into every session
3. Your preferences, tech stack, and coding style are always available

Example Soul file

# 🧠 Soul — Global Identity

## 👤 Identity
- GitHub: your-username
- Role: Developer/Designer/Product Manager

## 💻 Tech Stack
- TypeScript, React, Node.js, DSH/Cordis

## 🎨 Coding Style
- Functional programming
- ES Modules
- Zero-config preferred

## ⚠️ Preferences
- No class components
- No redundant comments

Installation

npm install @deepseek-ai/dsh-memory-connect

Add to your DSH composition:

# agent.cordis.yml
- id: memory
  name: '@deepseek-ai/dsh-memory-connect'
  config:
    path: ~/.dsh/memory.db
    enableSoul: true  # Enable Soul injection (default: true)

Configuration

Basic Options

Option	Default	Description
path	(required)	Path to SQLite memory database
openAt	startup	When to open: startup, first-query, never
maxRecallCount	10	Max memories to recall per session
decayRate	0.02	Decay constant (higher = faster decay)
journalMode	wal	SQLite journal mode

Scheduler Options

Option	Default	Description
schedulerEnabled	true	Enable periodic maintenance
schedulerDecayIntervalMs	3600000	Decay interval (ms), default 1h
schedulerConsolidateIntervalMs	21600000	Consolidation interval (ms), default 6h

Context Explosion Prevention Options

Option	Default	Description
maxContextTokens	4000	Max tokens for memory context injection
smartPrioritization	true	Enable smart memory prioritization
enableCompression	true	Enable memory compression

Soul Options

Option	Default	Description
enableSoul	true	Enable global Soul injection
soulPath	~/.dsh/soul.md	Custom Soul file path

Full configuration example:

- id: memory
  name: '@deepseek-ai/dsh-memory-connect'
  config:
    path: ~/.dsh/memory.db
    openAt: startup
    maxRecallCount: 10
    decayRate: 0.02
    journalMode: wal
    schedulerEnabled: true
    maxContextTokens: 4000
    smartPrioritization: true
    enableCompression: true
    enableSoul: true

API

Search Memories

const memories = await ctx.crossSessionMemory.searchMemories({
  query: 'TypeScript configuration',
  types: ['fact', 'decision'],
  limit: 5,
})

Recall for Session

const memories = await ctx.crossSessionMemory.recallForSession(
  'session-123',
  'Setting up a new React project',
  10
)

Store Memory

await ctx.crossSessionMemory.storeMemory({
  type: 'preference',
  content: 'User prefers functional programming style',
  sessionId: 'session-123',
  tags: ['coding-style', 'preference'],
})

Manual Maintenance

// Trigger a full maintenance cycle (decay + consolidation)
const result = await ctx.crossSessionMemory.triggerMaintenance()

// Or run individually
await ctx.crossSessionMemory.runDecay()
await ctx.crossSessionMemory.consolidate()

Context Explosion Prevention

How It Works

1. Token Counting — Estimates tokens for English, Chinese, and mixed text
2. Smart Prioritization — Ranks memories by: relevance × 50% + recency × 30% + frequency × 20%
3. Budget Management — Enforces maxContextTokens limit (default: 4000)
4. Memory Compression — Automatically truncates or summarizes when approaching limits

Output Example

概述

dsh-memory-connect 是 DeepSeek Harness 的跨会话记忆共享插件。它自动从对话中提取、存储和检索记忆，让 AI Agent 拥有持久化的智能记忆能力，并防止上下文爆炸和全局身份。

零配置 — 基于 SQLite FTS5 和 DSH 内置 LLM，开箱即用。

核心功能

功能	说明
🧠 全局身份 (Soul)	通过 ~/.dsh/soul.md 跨所有工作区持久化身份
🔍 自动提取	从对话中提取事实、偏好、决策和上下文
🧠 语义召回	RRF 融合关键词和语义搜索
🛡️ 上下文爆炸防护	Token 预算管理，防止上下文窗口溢出
⏰ 定时维护	内置调度器自动执行衰减和整合
🤖 LLM 整合	使用 DSH 内置 LLM 智能合并相似记忆
📉 记忆衰减	旧的、不常用的记忆自然消退
🎯 智能优先级	基于相关性 × 时间 × 频率的记忆排序
🗜️ 记忆压缩	接近 token 限制时自动压缩

🧠 全局身份 (Soul)

Soul 功能提供跨所有工作区的持久化身份。

工作原理

1. 创建 ~/.dsh/soul.md 包含你的身份信息
2. 插件自动加载并注入到每个会话
3. 你的偏好、技术栈和编码风格始终可用
