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.

- 👤 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!
📖 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)
pip install clawbrain[all]
clawbrain setup
clawbrain backup-key --all
sudo systemctl restart clawdbot
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)
cd ~/.openclaw/skills
git clone https://github.com/clawcolab/clawbrain.git
cd clawbrain
cat hooks/clawbrain-startup/handler.js
pip install -e .[all]
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:
export BRAIN_AGENT_ID="your-agent-name"
Option 2: Systemd Drop-in (Requires sudo)
⚠️ Only if you use systemd services:
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:
clawbrain setup
clawbrain backup-key --all
Usage:
brain.remember(
agent_id="assistant",
memory_type="secret",
content="sk-1234567890abcdef",
key="openai_api_key"
)
secrets = brain.recall(agent_id="assistant", memory_type="secret")
api_key = secrets[0].content
Key Management CLI:
clawbrain show-key
clawbrain show-key --full
clawbrain backup-key --all
clawbrain generate-key
⚠️ Important: Backup your encryption key! Lost keys = lost encrypted data.

ClawBrain includes a command-line interface:
| Command | Description |
|---|

clawbrain generate-key | Generate new encryption key |
clawbrain show-key | Display current encryption key |

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):
context = self.brain.get_full_context(
session_key=f"telegram_{chat_id}",
user_id=str(chat_id),
agent_id="assistant",
message=message
)
response = self.generate_response(context)
self.brain.learn_user_preference(
user_id=str(chat_id),
pref_type="interest",
value="AI"
)
return response
def generate_response(self, context):
name = context["user_profile"].name or "there"
mood = context["mood"]["mood"]
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()
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'
sys.path.insert(0, "ClawBrain")
PostgreSQL connection failed
echo $POSTGRES_HOST
echo $POSTGRES_PORT
pg_isready -h $POSTGRES_HOST -p $POSTGRES_PORT

Using SQLite (fallback)
If PostgreSQL/Redis are unavailable, Claw Brain automatically falls back to SQLite:
brain = Brain({"storage_backend": "sqlite"})
