OpenViking Setup

Set up OpenViking context database for OpenClaw agents. OpenViking is an open-source context database designed specifically for AI agents with filesystem-based memory management, tiered context loading (L0/L1/L2), and self-evolving memory. Use when asked to set up OpenViking, configure context database for agents, implement persistent memory, or when memory management optimization is needed. Triggers on "install openviking", "setup openviking", "context database", "tiered memory", "L0 L1 L2 context".

OpenViking Setup for OpenClaw

OpenViking brings filesystem-based memory management to AI agents with tiered context loading and self-evolving memory. This skill guides you through installation and configuration.

What OpenViking Provides

• Filesystem paradigm: Unified context management (memories, resources, skills)
• Tiered loading (L0/L1/L2): Load only what's needed, save tokens
• Self-evolving memory: Gets smarter with use
• OpenClaw plugin: Native integration available

Prerequisites

• Python 3.10+
• Go 1.22+ (for AGFS components)
• GCC 9+ or Clang 11+ (for core extensions)
• VLM model access (for image/content understanding)
• Embedding model access (for vectorization)

Quick Start

Step 1: Install OpenViking

# Python package
pip install openviking --upgrade --force-reinstall

# CLI tool
curl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/crates/ov_cli/install.sh | bash

Step 2: Create Configuration

Create ~/.openviking/ov.conf:

{
  "storage": {
    "workspace": "/home/your-name/openviking_workspace"
  },
  "log": {
    "level": "INFO",
    "output": "stdout"
  },
  "embedding": {
    "dense": {
      "api_base": "https://api.openai.com/v1",
      "api_key": "your-openai-api-key",
      "provider": "openai",
      "dimension": 1536,
      "model": "text-embedding-3-small"
    },
    "max_concurrent": 10
  },
  "vlm": {
    "api_base": "https://api.openai.com/v1",
    "api_key": "your-openai-api-key",
    "provider": "openai",
    "model": "gpt-4o",
    "max_concurrent": 100
  }
}

Step 3: Configure Provider

OpenViking supports multiple VLM providers:

Provider	Model Example	Notes
openai	gpt-4o	Official OpenAI API
volcengine	doubao-seed-2-0-pro	Volcengine Doubao
litellm	claude-3-5-sonnet	Unified access (Anthropic, DeepSeek, Gemini, etc.)

For LiteLLM (recommended for flexibility):

{
  "vlm": {
    "provider": "litellm",
    "model": "claude-3-5-sonnet-20241022",
    "api_key": "your-anthropic-key"
  }
}

For Ollama (local models):

{
  "vlm": {
    "provider": "litellm",
    "model": "ollama/llama3.1",
    "api_base": "http://localhost:11434"
  }
}

OpenClaw Integration

Plugin Installation

OpenViking has a native OpenClaw plugin for seamless integration:

# Install OpenClaw plugin
pip install openviking-openclaw

# Or from source
git clone https://github.com/volcengine/OpenViking
cd OpenViking/plugins/openclaw
pip install -e .

Configuration for OpenClaw

Add to your OpenClaw config:

# ~/.openclaw/config.yaml
memory:
  provider: openviking
  config:
    workspace: ~/.openviking/workspace
    tiers:
      l0:
        max_tokens: 4000
        auto_flush: true
      l1:
        max_tokens: 16000
        compression: true
      l2:
        max_tokens: 100000
        archive: true

Memory Tiers Explained

Tier	Purpose	Token Budget	Behavior
L0	Active working memory	4K tokens	Always loaded, fast access
L1	Frequently accessed	16K tokens	Compressed, on-demand
L2	Archive/cold storage	100K+ tokens	Semantic search only

How Tiers Work

1. New context goes to L0
2. L0 fills → oldest items compressed to L1
3. L1 fills → oldest items archived to L2
4. Retrieval searches all tiers, returns relevant context

Directory Structure

~/.openviking/
├── ov.conf                 # Configuration
└── workspace/
    ├── memories/
    │   ├── sessions/        # L0: Active session memory
    │   ├── compressed/     # L1: Compressed memories
    │   └── archive/        # L2: Long-term storage
    ├── resources/          # Files, documents, assets
    └── skills/             # Skill-specific context

Usage Patterns

Adding Memory

from openviking import MemoryStore

store = MemoryStore()

# Add to L0
store.add_memory(
    content="User prefers Portuguese language responses",
    metadata={"tier": "l0", "category": "preference"}
)

# Add resource
store.add_resource(
    path="project_spec.md",
    content=open("project_spec.md").read()
)

Retrieving Context

# Semantic search across all tiers
results = store.search(
    query="user preferences",
    tiers=["l0", "l1", "l2"],
    limit=10
)

# Directory-based retrieval (more precise)
results = store.retrieve(
    path="memories/sessions/2026-03-16/",
    recursive=True
)

Compaction

# Trigger manual compaction
store.compact()

# View compaction status
status = store.status()
print(f"L0: {status.l0_tokens}/{status.l0_max}")
print(f"L1: {status.l1_tokens}/{status.l1_max}")

Best Practices

Memory Hygiene

1. Categorize entries: Use metadata tags for better retrieval
2. Flush L0 regularly: Let compaction run, don't hoard
3. Use directory structure: Organize by project/topic
4. Review L2 periodically: Archive stale memories

Token Efficiency

1. Let OpenViking manage tiers automatically
2. Use semantic search for L2 (don't load entire archive)
3. Compress verbose content before adding to L1
4. Keep L0 under 50% capacity for best performance

OpenClaw Workflow

1. Session starts → OpenViking loads L0
2. Conversation proceeds → context auto-promoted to L1/L2
3. Long gaps → L2 provides relevant historical context
4. Sessions compound → agent gets smarter over time

Troubleshooting

Common Issues

"No module named 'openviking'"

• Ensure Python 3.10+ is active
• Try pip install --user openviking

"Embedding model not found"

• Check ov.conf has correct provider and model
• Verify API key is valid

"L0 overflow"

• Reduce l0.max_tokens in config
• Manually call store.compact()

"Slow retrieval from L2"

• Consider pre-loading frequently accessed resources to L1
• Use directory-based retrieval for better precision

What Gets Better

After setup, your agent gains:

1. Persistent memory across sessions
2. Smarter retrieval with semantic + directory search
3. Token efficiency with tiered loading
4. Self-improvement as context accumulates
5. Observable context with retrieval trajectories

The more your agent works, the more context it retains—without token bloat.
