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.

Security & Transparency

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

What ClawBrain Does

• ✅ Stores memories locally (SQLite by default, PostgreSQL optional)
• ✅ Encrypts sensitive data (API keys, secrets) with Fernet encryption
• ✅ Installs startup hooks to ~/.openclaw/hooks or ~/.clawdbot/hooks
• ✅ Manages encryption keys at ~/.config/clawbrain/.brain_key

What ClawBrain Does NOT Do

• ❌ No telemetry - Does not phone home or collect usage data
• ❌ No external calls - Only connects to PostgreSQL/Redis if you configure them
• ❌ No sudo required - All operations in your home directory
• ❌ No code execution - Does not download or run remote code after install

Security Features

• 🔒 Encryption Key CLI: Can display full key for backup (with warnings)
• 🔍 Auditable: All code is open source and reviewable
• 📋 Documented Permissions: See SECURITY.md for full details

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

📖 Full Security Documentation: See SECURITY.md for:

• Threat model and protections
• Key management best practices
• What install scripts do
• Permissions required
• Network access (optional PostgreSQL/Redis)

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

1. Hook triggers on gateway:startup event
2. Detects storage backend (SQLite/PostgreSQL)
3. Loads memories for the configured BRAIN_AGENT_ID
4. Injects context into agent bootstrap

On /new Command

1. Hook triggers on command:new event
2. Saves current session summary to memory
3. Clears session state for fresh start

Storage Priority

1. PostgreSQL - If available and configured
2. SQLite - Fallback, zero configuration needed

---

Encrypted Secrets

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

Security Model:

• 🔐 Encryption key stored at ~/.config/clawbrain/.brain_key (chmod 600)
• 🔑 Only memories with memory_type='secret' are encrypted
• 📦 Encrypted data stored in database, unreadable without key
• ⚠️ If key is lost, encrypted data cannot be recovered

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.

Example: Full Integration

import sys
sys.path.insert(0, "ClawBrain")

from clawbrain import Brain

class AssistantBot:
    def __init__(self):
        self.brain = Brain()
    
    def handle_message(self, message, chat_id):
        # Get context
        context = self.brain.get_full_context(

        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:

• PostgreSQL 14+
• Redis 6+
• Python packages: psycopg2-binary, redis

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"})
