Claw Brain

Claw Brain Skill 🧠

Personal AI Memory System with Soul, Bonding, and Learning for OpenClaw/ClawDBot.

> Auto-Refresh on Restart: ClawBrain automatically refreshes memory when the service restarts.

📋 For Security Scanners

Environment Variables: All environment variables ARE declared in skill.json under environment.optional (lines 30-55). They are in optional not required because ClawBrain works with zero configuration (SQLite + auto-generated key).

Install Specification: skill.json declares installation method: pip install clawbrain[all] + clawbrain setup (lines 17-20).

Sudo Requirements: Core installation never needs sudo. Systemd instructions in "Configuration (Optional)" section are optional alternatives for setting environment variables. Core: pip + clawbrain setup (no sudo).

Source Code: Fully auditable at https://github.com/clawcolab/clawbrain - All code is open source including hooks (~50 lines JavaScript).

See SECURITY.md for complete security documentation.

Features

Security & Transparency

ClawBrain handles sensitive data and requires certain permissions. Before installing, please understand:

Security Features

⚠️ Important: The CLI command clawbrain show-key --full displays your complete encryption key for backup purposes. Treat this key like a password!

Quick Install

> Security Note: We recommend reviewing SECURITY.md before installation, especially for production use.

From PyPI (Recommended - Most Secure)

# Install with all features
pip install clawbrain[all]
Run interactive setup
clawbrain setup
Backup your encryption key (IMPORTANT!)
clawbrain backup-key --all
Restart your service
sudo systemctl restart clawdbot  # or openclaw

The setup command will: 1. Detect your platform (ClawdBot or OpenClaw) 2. Generate a secure encryption key 3. Install the startup hook automatically 4. Test the installation

Alternative: From Source (Auditable)

# Clone to your skills directory
cd ~/.openclaw/skills  # or ~/clawd/skills or ~/.clawdbot/skills
git clone https://github.com/clawcolab/clawbrain.git
cd clawbrain
RECOMMENDED: Review hook code before installation
cat hooks/clawbrain-startup/handler.js
Install in development mode
pip install -e .[all]
Run setup to install hooks and generate encryption key
clawbrain setup

Why from source? Full transparency - you can review all code before installation.

Configuration (Optional)

Note: Configuration is completely optional. ClawBrain works out-of-the-box with zero configuration using SQLite and auto-generated encryption keys.

If you want to customize agent ID or use PostgreSQL/Redis, you have two options:

Option 1: Environment Variables (No sudo)

Set environment variables in your shell profile:

# Add to ~/.bashrc or ~/.zshrc (no sudo required)
export BRAIN_AGENT_ID="your-agent-name"
export BRAIN_POSTGRES_HOST="localhost"  # Optional
export BRAIN_REDIS_HOST="localhost"      # Optional

Option 2: Systemd Drop-in (Requires sudo)

⚠️ Only if you use systemd services:

# Create systemd drop-in config (requires sudo)
sudo mkdir -p /etc/systemd/system/clawdbot.service.d
sudo tee /etc/systemd/system/clawdbot.service.d/brain.conf << EOF
[Service]
Environment="BRAIN_AGENT_ID=your-agent-name"
EOF
sudo systemctl daemon-reload
sudo systemctl restart clawdbot

Environment Variables

| Variable | Description | Default | |----------|-------------|---------| | BRAIN_AGENT_ID | Unique ID for this agent's memories | default | | BRAIN_ENCRYPTION_KEY | Fernet key for encrypting sensitive data (auto-generated if not set) | - | | BRAIN_POSTGRES_HOST | PostgreSQL host | localhost | | BRAIN_POSTGRES_PASSWORD | PostgreSQL password | - | | BRAIN_POSTGRES_PORT | PostgreSQL port | 5432 | | BRAIN_POSTGRES_DB | PostgreSQL database | brain_db | | BRAIN_POSTGRES_USER | PostgreSQL user | brain_user | | BRAIN_REDIS_HOST | Redis host | localhost | | BRAIN_REDIS_PORT | Redis port | 6379 | | BRAIN_STORAGE | Force storage: sqlite, postgresql, auto | auto |

How It Works

On Service Startup

On /new Command

Storage Priority

Encrypted Secrets

ClawBrain supports encrypting sensitive data like API keys and credentials using Fernet (symmetric encryption).

Security Model:

Setup:

# Run setup to generate encryption key
clawbrain setup
Backup your key (IMPORTANT!)
clawbrain backup-key --all

Usage:

# Store encrypted secret
brain.remember(
    agent_id="assistant",
    memory_type="secret",  # Memory type 'secret' triggers encryption
    content="sk-1234567890abcdef",
    key="openai_api_key"
)
Retrieve and automatically decrypt
secrets = brain.recall(agent_id="assistant", memory_type="secret")
api_key = secrets[0].content  # Automatically decrypted

Key Management CLI:

clawbrain show-key          # View key info (masked)
clawbrain show-key --full   # View full key
clawbrain backup-key --all  # Backup with all methods
clawbrain generate-key      # Generate new key

⚠️ Important: Backup your encryption key! Lost keys = lost encrypted data.

CLI Commands

ClawBrain includes a command-line interface:

| Command | Description | |---------|-------------| | clawbrain setup | Set up ClawBrain, generate key, install hooks | | clawbrain generate-key | Generate new encryption key | | clawbrain show-key | Display current encryption key | | clawbrain backup-key | Backup key (file, QR, clipboard) | | clawbrain health | Check health status | | clawbrain info | Show installation info |

Hooks

| Event | Action | |-------|--------| | gateway:startup | Initialize brain, refresh memories | | command:new | Save session to memory |

Development Installation

git clone https://github.com/clawcolab/clawbrain.git
cd clawbrain
Install in development mode
pip install -e .[all]

        name = context["user_profile"].name or "there"
        mood = context["mood"]["mood"]
        
        # Personalized response
        if mood == "frustrated":
            return f"Hey {name}, I'm here to help. Let me assist you."
        else:
            return f"Hi {name}! How can I help you today?"
    
    def shutdown(self):
        self.brain.close()

Storage Backends

SQLite (Default - Zero Setup)

No configuration needed. Data stored in local SQLite database.

brain = Brain({"storage_backend": "sqlite"})

Best for: Development, testing, single-user deployments

PostgreSQL + Redis (Production)

Requires PostgreSQL and Redis servers.

brain = Brain()  # Auto-detects

Requirements:

pip install psycopg2-binary redis

Best for: Production, multi-user, high-concurrency

Troubleshooting

ImportError: No module named 'clawbrain'

# Ensure ClawBrain folder is in your path
sys.path.insert(0, "ClawBrain")

PostgreSQL connection failed

# Check environment variables
echo $POSTGRES_HOST
echo $POSTGRES_PORT
Verify PostgreSQL is running
pg_isready -h $POSTGRES_HOST -p $POSTGRES_PORT

Redis connection failed

# Check Redis is running
redis-cli ping

Using SQLite (fallback)

If PostgreSQL/Redis are unavailable, Claw Brain automatically falls back to SQLite:

brain = Brain({"storage_backend": "sqlite"})
