🧠 Obsidian Memory for DeepSeek Harness — persistent memory via local Markdown vault

A DSH plugin that gives your AI agent persistent memory backed by a local Obsidian (or plain Markdown) vault. It registers 5 file-system tools (obsidian_memory_*) and renders a sidebar panel showing vault status and tool reference.

Inspired by @Saccc_c's Codex memory techniques.

---

What it does

• 5 memory tools — AI can read, list, search, write, and append to your local vault
• Sidebar panel — renders inside the sidebar.obsidian-memory slot in DSH's left column
• No external server — talks directly to the file system via DSH's host runtime
• Codex-compatible — works with the Codex/ directory structure recommended by the community

Available Tools

Tool	Action
obsidian_memory_read	Read a Markdown or text file
obsidian_memory_list	List files and directories
obsidian_memory_search	Full-text search across .md and .txt files
obsidian_memory_write	Write or overwrite a file
obsidian_memory_append	Append content to the end of a file

---

Quick Start

1. Prepare your vault

Create a Codex/ folder anywhere on your machine (e.g. inside an Obsidian vault):

~/Documents/Obsidian Vault/
└── Codex/
    ├── AGENTS.md      ← AI operating instructions
    ├── TODO.md        ← pending tasks / open loops
    ├── people/
    ├── projects/
    ├── notes/
    └── daily/

2. Install the plugin

cd ~/.dsh/profiles/web        # or your DSH profile directory
npm install dsh-client-ui-obsidian-memory

If you installed DSH from source and don't use profiles, install into the DSH workspace root instead.

3. Add to cordis.patch.yml

Edit your profile's cordis.patch.yml (or cordis.yml):

- insert:
    - id: ui-obsidian-memory
      name: dsh-client-ui-obsidian-memory
      config:
        vaultPath: /Users/YOURNAME/Documents/Obsidian Vault/Codex

Replace vaultPath with the absolute path to your Codex/ folder.

Note: insert (not just id + config) is required so DSH loads the host-side tool plugin. If you only add id: ui-obsidian-memory with config, the sidebar UI may load but the tools will not be registered.

4. Restart DSH

dsh web   # or however you launch DSH

After restart:

• The sidebar panel appears in the left column (🧠 Obsidian Memory)
• The 5 tools are available to the AI when vaultPath is configured

---

Configuration

Option	Type	Default	Description
vaultPath	string	—	Absolute path to your Codex/ vault directory

Environment variable fallback (optional):

export OBSIDIAN_VAULT_PATH=/Users/YOURNAME/Documents/Obsidian Vault/Codex

If neither vaultPath in config nor the env var is set, the plugin logs a warning and skips tool registration.

Component	Role
Host (lib/index.js)	Node side: registers tools, reads/writes vault files
Client (lib/client.js)	Browser side: sidebar panel with static tool reference
Vault	Data source: local Markdown files

Troubleshooting

Symptom	Cause	Fix
Plugin not in Settings → Plugins	insert missing in cordis.patch.yml	Add the insert block (see Quick Start step 3)
Tools not available to AI	vaultPath not configured	Set vaultPath in cordis.patch.yml or env var
Sidebar panel not visible	DSH version lacks sidebar.obsidian-memory slot	Upgrade DSH to ≥ 0.1.0-rc.5
"Path traversal detected" error	AI tried to access files outside vault	All paths are sandboxed to vaultPath

Development

git clone https://github.com/detongz/dsh-client-ui-obsidian-memory.git
cd dsh-client-ui-obsidian-memory/plugin
npm install
npm run build        # outputs lib/index.js + lib/client.js
npm run watch        # dev mode with auto-rebuild

Build artifacts:

• lib/index.js — host entry (tool registration + file I/O)
• lib/client.js — browser bundle (DSH closure-factory format, CSS inlined)
