Unlike simple watchdogs that just restart processes, this system understands why things broke and how to fix them — thanks to Claude Code acting as an emergency doctor.

🏗️ Architecture

┌─────────────────────────────────────────────────────────┐
│ Level 1: Gateway KeepAlive (instant)                    │
│ ├─ LaunchAgent: ai.openclaw.gateway                     │
│ └─ launchd auto-restart on crash                        │
└─────────────────────────────────────────────────────────┘
                         ↓ (if Gateway needs monitoring)
┌─────────────────────────────────────────────────────────┐
│ Level 2: Watchdog (180s interval) 🔍                    │
│ ├─ LaunchAgent: ai.openclaw.watchdog + KeepAlive       │
│ ├─ PID check + HTTP health check                        │
│ ├─ Memory monitoring (1.5GB warning, 2GB critical)      │
│ ├─ Exponential backoff (10s → 600s)                     │

┌─────────────────────────────────────────────────────────┐

│ ├─ Cron-based (independent from launchd)                │
│ ├─ Detects "loaded but not running" state (PID -)       │
│ ├─ Auto-kickstart hung services                         │
│ └─ Discord alert on recovery                            │
└─────────────────────────────────────────────────────────┘
                         ↓ (monitoring for escalation)

Installation

# 1. Clone this repository (or copy scripts to your workspace)
cd ~/openclaw
git clone https://github.com/ramsbaby/openclaw-self-healing.git
cd openclaw-self-healing

# 2. Install dependencies
brew install tmux
npm install -g @anthropic-ai/claude-code

# 3. Copy environment template
cp .env.example ~/.openclaw/.env

# 4. Edit .env with your Discord webhook (optional)
nano ~/.openclaw/.env
# Set DISCORD_WEBHOOK_URL to your webhook URL

# 5. Copy scripts to OpenClaw workspace
cp scripts/*.sh ~/openclaw/scripts/
cp scripts/launchd-guardian.sh ~/.openclaw/scripts/
chmod +x ~/openclaw/scripts/*.sh ~/.openclaw/scripts/*.sh

# 6. Load Watchdog LaunchAgent (v1.1.0+ with KeepAlive)
cp launchagent/ai.openclaw.watchdog.plist ~/Library/LaunchAgents/
launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/ai.openclaw.watchdog.plist

# 7. Add Guardian cron (watches the watchdog)
(crontab -l 2>/dev/null; echo "*/3 * * * * /bin/bash ~/.openclaw/scripts/launchd-guardian.sh 2>/dev/null") | crontab -

# 8. Verify installation
launchctl list | grep openclaw.watchdog
# Expected: PID (running) or - (waiting for next interval)

Verification

# Check Health Check is running
launchctl list | grep openclaw.healthcheck

# View Health Check logs
tail -f ~/openclaw/memory/healthcheck-$(date +%Y-%m-%d).log

# Simulate a crash (optional)
kill -9 $(pgrep -f openclaw-gateway)
# Wait 3 minutes, then check if it auto-recovered
curl http://localhost:18789/

⚙️ Configuration

All settings via environment variables in ~/.openclaw/.env:

Variable	Default	Description

See .env.example for full configuration options.

🧪 Testing

Level 1: Watchdog

# Kill Gateway process
kill -9 $(pgrep -f openclaw-gateway)

# Wait 3 minutes (180s)
sleep 180

# Verify recovery
curl http://localhost:18789/
# Expected: HTTP 200

Level 2: Health Check

# View Health Check logs
tail -f ~/openclaw/memory/healthcheck-$(date +%Y-%m-%d).log

# Health Check runs every 5 minutes
# Look for "✅ Gateway healthy" or retry attempts

Level 3: Claude Recovery

# Inject a config error (backup first!)
cp ~/.openclaw/openclaw.json ~/.openclaw/openclaw.json.bak

# Edit config to break Gateway (e.g., invalid port)
# Then restart Gateway
openclaw gateway restart

# Wait ~8 minutes (Health Check detects + escalates)
# Watch for Level 3 trigger
tail -f ~/openclaw/memory/emergency-recovery-*.log

Level 4: Discord Notification

# Simulate Level 3 failure
cat > ~/openclaw/memory/emergency-recovery-test-$(date +%Y-%m-%d-%H%M).log << 'EOF'
[2026-02-06 20:00:00] === Emergency Recovery Started ===
[2026-02-06 20:30:00] Gateway still unhealthy (HTTP 500)

=== MANUAL INTERVENTION REQUIRED ===
Level 1 (Watchdog) ❌
Level 2 (Health Check) ❌
Level 3 (Claude Recovery) ❌
EOF

# Run monitor script
~/openclaw/scripts/emergency-recovery-monitor.sh

# Check Discord for alert (or console output if webhook not set)

🔒 Security

Discord Webhook Protection

Never commit your webhook URL to Git.

# ✅ CORRECT: Use .env
echo 'DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/..."' >> ~/.openclaw/.env

# ❌ WRONG: Hardcode in scripts
# This will leak your webhook to anyone who clones your repo

Log File Permissions

Claude session logs may contain sensitive data (API keys, tokens). Scripts set chmod 600 on logs by default.

Claude Code Permissions

Level 3 grants Claude Code access to:

OpenClaw config (~/.openclaw/openclaw.json)
Gateway restart (openclaw gateway restart)
Log files (~/.openclaw/logs/*.log)

This is intentional for autonomous recovery, but review emergency-recovery.sh if concerned.

🐛 Known Issues & Fixes

⚠️ v1.0.0 Critical Bug (Fixed in v1.1.0)

Issue: Self-healing system failed to recover from Watchdog hang (discovered 2026-02-07)

Symptoms:

Watchdog hung after sending SIGUSR1
launchd didn't restart Watchdog (no KeepAlive)
Guardian only checked "loaded" status, missed "loaded but PID=-"
System down for 13+ hours

Root Cause:

StartInterval services don't auto-restart without KeepAlive
Guardian's detection logic was incomplete

Fix (v1.1.0):

✅ Added KeepAlive to ai.openclaw.watchdog.plist
✅ Guardian now detects PID=- and kickstarts hung services
✅ All timeouts verified (HTTP: 5s, no infinite hangs)

Upgrade: See v1.1.0 Release Notes for migration guide.

🚧 Current Limitations

1. macOS Only

LaunchAgent is macOS-specific
Linux users: See docs/LINUX_SETUP.md for systemd equivalents

2. Claude CLI Dependency

Level 3 fails if Claude API quota is exhausted
Fallback: System escalates to Level 4 (human alert)

3. Network Dependency

Level 3 requires Claude API access
Level 4 requires Discord API access
Offline recovery: Only Level 1-3 work

4. No Multi-Node Support (yet)

Designed for single Gateway
Cluster support: Roadmap Phase 3

🗺️ Roadmap

Phase 1: ✅ Core System (Complete)

4-tier escalation architecture
Claude Code integration
Production testing
Documentation

Phase 2: 🚧 Community Refinement (Current)

Linux (systemd) support
GPT-4/Gemini alternative LLMs
Prometheus metrics export
Grafana dashboard template

Phase 3: 🔮 Future (3+ months)

Multi-node cluster support
Self-learning failure patterns
GitHub Issues auto-creation
Slack/Telegram notification channels
