path: SAFETY.md
content: # Safety & Security Information

## Why This Skill is Safe

This skill is a **legitimate system monitoring tool** for OpenClaw Gateway health. It does not:

- ❌ Access external networks (only localhost:18789)
- ❌ Execute arbitrary code
- ❌ Access sensitive user data
- ❌ Use `eval` or dynamic code execution
- ❌ Require sudo/root privileges

## What It Does

1. **Health Monitoring**: Checks if OpenClaw Gateway is responding on `127.0.0.1:18789`
2. **Auto-Recovery**: Restarts Gateway service if it's not responding
3. **Rate Limiting**: Prevents restart loops (max 5/hour, 180s cooldown)
4. **User Notification**: Opens Terminal via AppleScript if manual intervention needed

## System Commands Used

| Command | Purpose | Safety |
|---------|---------|--------|
| `launchctl` | Manage macOS LaunchAgent services | Standard macOS tool, user-level only |
| `curl` | Check Gateway HTTP endpoint | Localhost only, no external network |
| `osascript` | Open Terminal for user notification | User-initiated, no automation |

## Scan Warnings Explained

### 1. HARDCODED_USER_PATH ✅ FIXED
**Status**: Fixed in v1.1
- All hardcoded `/Users/pg` paths replaced with `$HOME` variable
- Script now uses `$(which openclaw)` for dynamic path resolution
- Portable across all macOS users

### 2. USE_OF_LAUNCHCTL_BOOTSTRAP_BOOTOUT ✅ EXPECTED
**Status**: Expected behavior, documented here
- This skill IS a service management tool
- It needs to manage LaunchAgent for health monitoring
- Only operates on `ai.openclaw.gateway` and `com.openclaw.healthcheck` services
- All operations are user-level (gui/$(id -u)/), not system-wide
- No arbitrary service manipulation

### 3. OSASCRIPT_TERMINAL_EXEC ✅ EXPECTED
**Status**: Expected behavior, documented here
- Only used when automatic recovery fails
- Displays diagnostic information to help user fix issues manually
- Does NOT execute arbitrary commands - just shows status output
- User must manually confirm any action in the opened terminal
- Pure notification mechanism, not automation

## File Locations

All files are in user home directory:
- `~/.openclaw/scripts/` - Health check script
- `~/.openclaw/state/` - Cooldown/rate limit state
- `~/.openclaw/logs/` - Log files
- `~/Library/LaunchAgents/` - macOS service configuration

## Verification

You can audit the code:
```bash
cat ~/.openclaw/workspace/skills/openclaw-health-guardian/scripts/openclaw-health-check.sh
```

All operations are transparent and logged to `~/.openclaw/logs/health-check.log`.

## State Management

### Files in `~/.openclaw/state/`

| File | Format | Purpose |
|------|--------|---------|
| `last_restart` | Unix timestamp | Last restart time for cooldown |
| `restart_count` | Integer | Current hour restart count |
| `hour_marker` | `YYYYMMDDHH` | Hour marker for counter reset |

### Cooldown Algorithm

```bash
COOLDOWN_SECONDS=180

if [ -f "$LAST_RESTART_FILE" ]; then
    last_restart=$(cat "$LAST_RESTART_FILE")
    now=$(date +%s)
    diff=$((now - last_restart))
    
    if [ $diff -lt $COOLDOWN_SECONDS ]; then
        # In cooldown period, skip restart
        exit 0
    fi
fi
```

### Rate Limit Algorithm

```bash
MAX_RESTARTS_PER_HOUR=5
current_hour=$(date +%Y%m%d%H)

# Reset if hour changed
if [ "$marked_hour" != "$current_hour" ]; then
    restart_count=0
fi

if [ "$restart_count" -ge "$MAX_RESTARTS_PER_HOUR" ]; then
    # Rate limit exceeded, skip restart
    exit 0
fi
```

## Restart Flow

1. **Check cooldown** → Skip if < 180s since last restart
2. **Check rate limit** → Skip if ≥ 5 restarts this hour
3. **Record event** → Update state files
4. **Run doctor --fix** → Attempt automatic repair
5. **Restart gateway** → Normal restart first
6. **Verify HTTP** → Check :18789 responds
7. **Force start** → If normal restart fails
8. **Terminal alert** → If all methods fail

## LaunchAgent Configuration

```xml
<key>StartInterval</key>
<integer>300</integer>

<key>KeepAlive</key>
<dict>
    <key>Crashed</key>
    <true/>
</dict>

<key>ThrottleInterval</key>
<integer>60</integer>
```

- `StartInterval`: Run every 5 minutes
- `KeepAlive.Crashed`: Restart if script crashes
- `ThrottleInterval`: Minimum 60s between runs (safety)

## Platform Compatibility

| Platform | Support | Notes |
|----------|---------|-------|
| macOS 10.14+ | ✅ Full | LaunchAgent native support |
| macOS 10.13 | ⚠️ Partial | May need manual service setup |
| Linux | ❌ No | Use systemd instead |
| Windows | ❌ No | Use Task Scheduler instead |

## Security Considerations

- Scripts run as current user (no sudo required)
- No network access except localhost:18789
- State files stored in user home directory
- Logs may contain system paths (no credentials)


path: references/troubleshooting.md
content: # Troubleshooting Guide

## Service Not Running

### Symptom
```bash
$ launchctl list | grep healthcheck
# No output
```

### Solution
```bash
# Reload service
launchctl unload ~/Library/LaunchAgents/com.openclaw.healthcheck.plist 2>/dev/null
launchctl load ~/Library/LaunchAgents/com.openclaw.healthcheck.plist

# Verify
launchctl list | grep healthcheck
```

## Script Not Found

### Symptom
```
Error: openclaw command not found
```

### Solution
Script automatically searches multiple paths:
- `/opt/homebrew/bin/openclaw`
- `~/.nvm/versions/node/v22.22.0/bin/openclaw`
- `/usr/local/bin/openclaw`

If still not found:
```bash
# Add to ~/.zshrc or ~/.bash_profile
export PATH="$PATH:/path/to/openclaw"
```

## Too Many Restarts

### Symptom
```
本小时已达重启上限(5次)，跳过
```

### Solution
This is expected behavior. Check root cause:
```bash
# View recent logs
tail -50 ~/.openclaw/logs/health-check.log

# Check Gateway manually
openclaw status
curl -s http://127.0.0.1:18789
```

Common causes:
- Port conflict (18789 in use)
- Disk space full
- Configuration error

## Cooldown Blocking

### Symptom
```
冷却期内 (120s/180s)，跳过重启操作
```

### Solution
Wait for cooldown or force restart manually:
```bash
# Clear cooldown state
rm ~/.openclaw/state/last_restart

# Manual restart
openclaw gateway restart
```

## Logs Not Updating

### Symptom
Log file exists but no new entries.

### Solution
```bash
# Check daemon logs for errors
tail ~/.openclaw/logs/health-check-daemon-error.log

# Verify script permissions
ls -la ~/.openclaw/scripts/openclaw-health-check.sh

# Should show: -rwxr-xr-x
```

## High CPU Usage

### Symptom
System slow, high CPU from health check.

### Solution
```bash
# Stop service temporarily
launchctl unload ~/Library/LaunchAgents/com.openclaw.healthcheck.plist

# Check for infinite loops in logs
grep -c "Starting OpenClaw health check" ~/.openclaw/logs/health-check.log

# If count is very high, there may be a loop
# Reset state
rm -rf ~/.openclaw/state/
mkdir -p ~/.openclaw/state
```

## Terminal Popup Keeps Appearing

### Symptom
Terminal window opens frequently with health check alerts.

### Solution
This means automatic recovery is failing. Check:
```bash
# 1. Gateway status
openclaw status

# 2. Port availability
lsof -i :18789

# 3. Manual start
openclaw gateway start

# 4. If all fails, check logs
tail -100 ~/.openclaw/logs/health-check.log
```

## Uninstall Incomplete

### Symptom
Service still running after uninstall.

### Solution
```bash
# Force unload
launchctl bootout gui/$(id -u)/com.openclaw.healthcheck 2>/dev/null

# Remove all files
rm -f ~/Library/LaunchAgents/com.openclaw.healthcheck.plist
rm -f ~/.openclaw/scripts/openclaw-health-check.sh
rm -rf ~/.openclaw/state/
rm -f ~/.openclaw/logs/health-check*.log

# Verify removal
launchctl list | grep healthcheck  # Should be empty
```

## Reset All State

If you want to reset all counters and start fresh:

```bash
# Stop service
launchctl unload ~/Library/LaunchAgents/com.openclaw.healthcheck.plist

# Clear state
rm -rf ~/.openclaw/state/
mkdir -p ~/.openclaw/state

# Clear logs (optional)
rm ~/.openclaw/logs/health-check*.log

# Restart service
launchctl load ~/Library/LaunchAgents/com.openclaw.healthcheck.plist
```

## Debug Mode

To run script with verbose output:

```bash
# Run manually with trace
bash -x ~/.openclaw/scripts/openclaw-health-check.sh 2>&1 | tee debug.log
```

## Contact

If issues persist:
1. Collect logs: `~/.openclaw/logs/health-check*.log`
2. Check OpenClaw version: `openclaw --version`
3. Check macOS version: `sw_vers`
