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

🎭 Soul/Personality - 6 evolving traits (humor, empathy, curiosity, creativity, helpfulness, honesty)
👤 User Profile - Learns user preferences, interests, communication style
💭 Conversation State - Real-time mood detection and context tracking
📚 Learning Insights - Continuously learns from interactions and corrections
🧠 get_full_context() - Everything for personalized responses
🔄 Auto-Refresh - Automatically refreshes memory on service restart
🔐 Encrypted Secrets - Store API keys and credentials securely

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!

Quick Install

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

From PyPI (Recommended - Most Secure)

bash

# 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:

Detect your platform (ClawdBot or OpenClaw)
Generate a secure encryption key
Install the startup hook automatically
Test the installation

Alternative: From Source (Auditable)

bash

# 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:

bash

# 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:

bash

# 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

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

On `/new` Command

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

Storage Priority

PostgreSQL - If available and configured
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:

bash

# Run setup to generate encryption key
clawbrain setup

# Backup your key (IMPORTANT!)
clawbrain backup-key --all

Usage:

python

# 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:

bash

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.

Storage Backends

SQLite (Default - Zero Setup)

No configuration needed. Data stored in local SQLite database.

python

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

Best for: Development, testing, single-user deployments

PostgreSQL + Redis (Production)

Requires PostgreSQL and Redis servers.

python

brain = Brain()  # Auto-detects

Requirements:

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

bash

pip install psycopg2-binary redis

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

Troubleshooting

ImportError: No module named 'clawbrain'

bash

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

PostgreSQL connection failed

bash

# Check environment variables
echo $POSTGRES_HOST
echo $POSTGRES_PORT

# Verify PostgreSQL is running
pg_isready -h $POSTGRES_HOST -p $POSTGRES_PORT

Redis connection failed

bash

# Check Redis is running
redis-cli ping

Using SQLite (fallback)

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

python

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