# OpenClaw Self-Healing System

> **"The system that heals itself — or calls for help when it can't."**

A production-ready, 4-tier autonomous recovery system for [OpenClaw](https://github.com/openclaw/openclaw) Gateway, featuring AI-powered diagnosis and repair via Claude Code.

*The 4-tier recovery in action: Watchdog → Health Check → Claude Doctor → Alert*

---

## 🌟 Why This Exists

OpenClaw Gateway crashes happen. Health checks fail. Developers wake up to dead agents.

**This system watches your watcher.** When OpenClaw goes down, it:

1. **Restarts it** (Level 1-2, seconds)
2. **Diagnoses the problem** (Level 3, AI-powered)
3. **Fixes the root cause** (Level 3, autonomous)
4. **Alerts you** (Level 4, only if all else fails)

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)                     │
│ └─ SIGUSR1 graceful restart or launchctl kickstart      │
└─────────────────────────────────────────────────────────┘
                         ↓ (if Watchdog hangs/crashes)
┌─────────────────────────────────────────────────────────┐
│ Level 3: LaunchAgent Guardian (180s cron) 🛡️           │
│ ├─ Cron-based (independent from launchd)                │
│ ├─ Detects "loaded but not running" state (PID -)       │
│ ├─ Auto-kickstart hung services                         │
│ └─ Discord alert on recovery                            │
└─────────────────────────────────────────────────────────┘
                         ↓ (monitoring for escalation)
┌─────────────────────────────────────────────────────────┐
│ Level 4: Discord Notification 🚨                        │
│ ├─ 3 consecutive failures → alert                       │
│ ├─ 15-minute cooldown between alerts                    │
│ └─ Detailed failure context + logs                      │
└─────────────────────────────────────────────────────────┘

launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/ai.openclaw.watchdog.plist

# 7. Add Guardian cron (watches the watchdog)

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

## 🧪 Testing

### Level 1: Watchdog

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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.**

```bash
# ✅ 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:**
1. StartInterval services don't auto-restart without KeepAlive
2. 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](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)

---

## 🗺️ Roadmap
