Install OpenViking Memory for OpenClaw

This skill installs OpenViking as the memory backend for OpenClaw. After installation, OpenClaw will automatically remember facts from conversations and recall relevant context.

For AI Agents: Follow the steps below in order. Run each command, check the output, and only proceed when the step passes. Ask the user for input only where indicated with [ASK USER].

---

Step 1: Check Prerequisites

Run all checks below. Every check must pass before continuing.

1.1 Check Node.js (>= 22)

node -v

• Pass: Output shows v22.x.x or higher.
• Fail: Tell the user: "Node.js >= 22 is required. Install it from https://nodejs.org/ or use nvm: nvm install 22"

1.2 Check Python (>= 3.10)

Linux / macOS:

python3 --version

Windows:

python --version

• Pass: Output shows Python 3.10.x or higher.
• Fail: Tell the user: "Python >= 3.10 is required. See INSTALL.md for installation instructions, or build from source: https://www.python.org/downloads/"

1.3 Check Build Tools (cmake, g++)

cmake --version
g++ --version

• Pass: Both commands return version info.
• Fail: Tell the user which tool is missing and how to install:
  • RHEL/CentOS/openEuler: sudo dnf install -y gcc gcc-c++ cmake make
  • Ubuntu/Debian: sudo apt install -y build-essential cmake
  • These tools are required — OpenClaw's node-llama-cpp dependency compiles C++ during installation, and OpenViking also has C++ extensions.

1.4 Check OpenClaw

openclaw --version

• Pass: Shows version output.
• Fail: Tell the user: "OpenClaw is required. Install with: npm install -g openclaw (if downloads are slow: npm install -g openclaw --registry=https://registry.npmmirror.com). After installing, run openclaw onboard to configure your LLM."

1.5 Check Go (>= 1.19) — only for source install on Linux

Skip this check if the user will install via pip install openviking --upgrade --force-reinstall (PyPI pre-built package).

go version

• Pass: Output shows go1.19.x or higher.
• Fail: Tell the user: "Go >= 1.19 is required for source installation on Linux (to compile AGFS). Download from https://go.dev/dl/ — see INSTALL.md for detailed steps."

---

Step 2: Clone and Install OpenViking

2.1 Clone Repository

If the OpenViking repo is not already present:

git clone https://github.com/volcengine/OpenViking.git
cd OpenViking

2.2 Install Python Package

Two options — choose based on the user's needs:

Option A: Install from PyPI (recommended, no Go needed)

python3 -m pip install openviking --upgrade --force-reinstall

Option B: Install from Source (developer mode)

Requires Go >= 1.19 on Linux (check passed in Step 1.5).

Linux / macOS:

python3 -m pip install -e . --force-reinstall

Windows:

python -m pip install -e . --force-reinstall

If pip downloads are slow, suggest using a mirror: python3 -m pip install openviking --upgrade --force-reinstall -i https://pypi.tuna.tsinghua.edu.cn/simple

2.3 Verify Installation

Linux / macOS:

python3 -c "import openviking; print('openviking module: ok')"

Windows:

python -c "import openviking; print('openviking module: ok')"

• Pass: Prints openviking module: ok.
• Fail — multiple Python versions: Ask the user which Python to use, then install with that path: /path/to/python3.11 -m pip install openviking --upgrade --force-reinstall
• Fail — TypeError: unsupported operand type(s) for |: Python version is below 3.10. The user needs to upgrade.
• Fail — Go compiler not found: Go is not installed (source install only). See Step 1.5.

---

Step 3: Run the Setup Helper

From the OpenViking repo root:

npx ./examples/openclaw-memory-plugin/setup-helper

The helper will interactively prompt for:

1. Workspace path — data storage location (default: absolute path of ~/.openviking/data, auto-detected)
2. Volcengine Ark API Key — [ASK USER] Direct them to https://console.volcengine.com/ark if they don't have one
3. VLM model — default doubao-seed-2-0-pro-260215, press Enter to accept
4. Embedding model — default doubao-embedding-vision-250615, press Enter to accept
5. Server ports — default 1933 (HTTP) and 1833 (AGFS), press Enter to accept

The helper will automatically:

• Create ~/.openviking/ov.conf
• Deploy the memory-openviking plugin into OpenClaw
• Configure OpenClaw to use local mode
• Write ~/.openclaw/openviking.env (Linux/macOS) or openviking.env.bat (Windows)

Wait for Setup complete! before proceeding.

---

Step 4: Start OpenClaw with Memory

Always load the env file first, then start the gateway:

Linux / macOS:

source ~/.openclaw/openviking.env && openclaw gateway

Windows (cmd):

call "%USERPROFILE%\.openclaw\openviking.env.bat" && openclaw gateway

Wait a few seconds. Verify this line appears in the output:

[gateway] memory-openviking: local server started (http://127.0.0.1:1933, ...)

• Pass: Tell the user: "OpenViking memory is now active. I will automatically remember important facts from our conversations and recall them when relevant."
• Fail — health check timeout: A stale process is blocking the port. Fix with:

  lsof -ti tcp:1933 tcp:1833 | xargs kill -9
  source ~/.openclaw/openviking.env && openclaw gateway

---

Step 5: Verify (Optional)

openclaw status

The Memory line should show: enabled (plugin memory-openviking)

Troubleshooting Quick Reference

Symptom	Cause	Fix
cmake not found during npm install	Missing build tools	sudo dnf install -y gcc gcc-c++ cmake make
Python.h: No such file or directory	Missing Python dev headers	sudo dnf install -y python3-devel (or python3.11-devel)
Go compiler not found	Go not installed	Install Go >= 1.19 from https://go.dev/dl/
dial tcp: i/o timeout (Go modules)	Network issue	go env -w GOPROXY=https://goproxy.cn,direct
ERR_INVALID_URL (npm)	Proxy missing http:// prefix	export https_proxy=http://host:port
extracted 0 memories	Wrong API key or model name	Check api_key and model in ~/.openviking/ov.conf
health check timeout	Stale process on port	Kill with lsof -ti tcp:1933 tcp:1833 | xargs kill -9
Plugin not loaded	Env file not sourced	Run source ~/.openclaw/openviking.env before gateway

---

Daily Usage

Each time the user wants to start OpenClaw with memory:

Linux / macOS:

source ~/.openclaw/openviking.env && openclaw gateway

Windows (cmd):

call "%USERPROFILE%\.openclaw\openviking.env.bat" && openclaw gateway

Suggest adding an alias for convenience:

echo 'alias openclaw-start="source ~/.openclaw/openviking.env && openclaw gateway"' >> ~/.bashrc

Enable/Disable the Memory Plugin Slot

Disable the memory plugin:

openclaw config set plugins.slots.memory none

Enable the OpenViking memory plugin:

openclaw config set plugins.slots.memory memory-openviking

If the gateway is already running, restart it after changing the slot.

---

Uninstall

Linux / macOS:

lsof -ti tcp:1933 tcp:1833 tcp:18789 | xargs kill -9
npm uninstall -g openclaw
rm -rf ~/.openclaw
python3 -m pip uninstall openviking -y
rm -rf ~/.openviking

Windows (cmd):

for /f "tokens=5" %a in ('netstat -ano ^| findstr "LISTENING" ^| findstr ":1933 :1833 :18789"') do taskkill /PID %a /F
npm uninstall -g openclaw
rmdir /s /q "%USERPROFILE%\.openclaw"
python -m pip uninstall openviking -y
rmdir /s /q "%USERPROFILE%\.openviking"
