🛡️ OpenClaw Guardian

A battle-hardened watchdog that keeps your OpenClaw gateway running — and tells you when it can't.

What It Does

OpenClaw Guardian runs as a background service and continuously monitors the OpenClaw gateway using two independent health signals. When the gateway goes down, it works through an escalating repair sequence before entering a cooldown and waiting for manual help. Every significant event is logged and sent to your configured alert channel(s).

Health Check Strategy (graduated)

1. CLI check — openclaw gateway status (the authoritative signal)
2. HTTP fallback — curl http://localhost:${OPENCLAW_PORT}/health (5s timeout)
3. Both must fail before the guardian considers the gateway truly down

Repair Strategy (escalating)

Note: Level 3 rollback is off by default and requires explicit opt-in via GUARDIAN_ENABLE_ROLLBACK=true. Even then, it always stashes uncommitted work before resetting — your changes are never silently discarded.

Alerting

Guardian supports both Telegram and Discord simultaneously. If neither is configured, it runs in log-only mode.

Alert events:

• Guardian started / stopped
• Gateway down detected
• Each repair attempt (with level)
• Repair success / failure
• Rollback triggered
• All repairs exhausted (cooldown entered)

Daily Snapshots

Once per calendar day, guardian runs git add -A && git commit in your workspace. It respects .gitignore, so secrets you've excluded stay excluded. Commit message format: guardian: daily snapshot YYYY-MM-DD.

Quick Start

1. Configure environment variables

Create ~/.openclaw/guardian.env (or export in your shell profile):

# Required for alerts — set at least one
export GUARDIAN_TELEGRAM_BOT_TOKEN="bot123456:ABC..."
export GUARDIAN_TELEGRAM_CHAT_ID="-1001234567890"
# OR
export GUARDIAN_DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/..."

# Optional tuning
export GUARDIAN_CHECK_INTERVAL=30
export GUARDIAN_MAX_REPAIR=3
export GUARDIAN_COOLDOWN=600
export GUARDIAN_ENABLE_ROLLBACK=false  # set true to enable git rollback
export GUARDIAN_WORKSPACE="$HOME/.openclaw/workspace"
export GUARDIAN_LOG="/tmp/openclaw-guardian.log"
export OPENCLAW_PORT=3578

2. Install as a system service

# macOS or Linux — auto-detects
./scripts/install-guardian.sh

# With a custom log path
GUARDIAN_LOG=/var/log/openclaw-guardian.log ./scripts/install-guardian.sh

3. Verify it's running

# macOS
launchctl list | grep openclaw

# Linux
systemctl --user status openclaw-guardian

# Both
tail -f /tmp/openclaw-guardian.log

4. Run manually (testing / foreground)

# Source your config first
source ~/.openclaw/guardian.env

# Run guardian in the foreground (Ctrl-C to stop)
./scripts/guardian.sh

5. Uninstall

./scripts/uninstall-guardian.sh

Logging

Logs are timestamped and structured:

[2026-03-05 11:30:00] [INFO] OpenClaw Guardian started (PID 12345)
[2026-03-05 11:30:30] [INFO] Gateway healthy
[2026-03-05 11:31:00] [WARN] CLI status check failed — trying HTTP health endpoint
[2026-03-05 11:31:05] [WARN] Gateway health check FAILED
[2026-03-05 11:31:05] [INFO] ALERT: 🔴 Gateway is DOWN — beginning repair sequence
[2026-03-05 11:31:05] [INFO] Repair Level 1: restarting gateway
[2026-03-05 11:31:35] [INFO] Level 1 repair succeeded

Log rotates automatically when it exceeds 1 MB (one backup: .log.1).

Security Notes

• No secrets in git — daily snapshots use git add -A which respects .gitignore. Ensure your .gitignore excludes .env, *.key, etc.
• Level 3 rollback is destructive by nature — only enable it if you understand git reset semantics and have tested your .gitignore coverage.
• Alert tokens in env only — never put GUARDIAN_TELEGRAM_BOT_TOKEN or webhook URLs in files that get committed.
