+# 🦞 openclaw-watchdog
+
+A standalone watchdog service for [OpenClaw](https://openclaw.dev) that monitors the gateway, auto-recovers from crashes, and sends Discord alerts when things go sideways.
+
+## What It Does
+
+- **Health monitoring** — Polls the gateway health endpoint at a configurable interval
+- **Auto-restart** — Restarts the gateway on first failure detection
+- **Config rollback** — Reverts to last-known-good config if a simple restart doesn't work
+- **Discord SOS alerts** — Sends a detailed alert with SSH instructions when all recovery fails
+- **Recovery notifications** — Lets you know when the gateway comes back online
+- **No spam** — Only alerts once per incident
+
+## Recovery Flow
+
+```
+Health check fails
+       │
+       ▼
+  ┌─────────────┐
+  │ Stage 1:    │──→ Simple restart
+  │ Restart     │
+  └──────┬──────┘
+         │ still failing
+         ▼
+  ┌─────────────┐
+  │ Stage 2:    │──→ Revert config to last-known-good + restart
+  │ Rollback    │
+  └──────┬──────┘
+         │ still failing
+         ▼
+  ┌─────────────┐
+  │ Stage 3:    │──→ Discord SOS with hostname & SSH instructions
+  │ SOS Alert   │
+  └─────────────┘
+```
+
+When the gateway recovers at any point, a ✅ recovery message is sent.
+
+## Prerequisites
+
+- [OpenClaw](https://openclaw.dev) installed with `openclaw` CLI available
+- Linux with systemd
+- `curl` and `jq`
+- Discord bot token (optional, for alerts)
+
+## Quick Install
+
+```bash
+git clone https://github.com/jlgrimes/openclaw-watchdog.git
+cd openclaw-watchdog
+chmod +x setup.sh watchdog.sh
+./setup.sh
+```
+
+The installer will:
+1. Copy `watchdog.sh` to `~/.openclaw/`
+2. Create a config file at `~/.openclaw/watchdog.env`
+3. Set up and start a systemd service
+
+## Configuration
+
+All settings live in `~/.openclaw/watchdog.env` (created by the installer):
+
+| Variable | Default | Description |
+|---|---|---|
+| `HEALTH_URL` | `http://localhost:3000/health` | Gateway health endpoint |
+| `CHECK_INTERVAL` | `30` | Seconds between health checks |
+| `FAIL_THRESHOLD` | `3` | Consecutive failures before SOS |
+| `OPENCLAW_CONFIG_PATH` | `~/.openclaw/config.yaml` | Path to OpenClaw config |
+| `DISCORD_CHANNEL_ID` | *(none)* | Discord channel for alerts |
+| `DISCORD_BOT_TOKEN` | *(none)* | Discord bot token for alerts |
+
+After editing, restart the service:
+
+```bash
+sudo systemctl restart openclaw-watchdog
+```
+
+## Manual Usage
+
+You can also run the watchdog directly:
+
+```bash
+export DISCORD_BOT_TOKEN="your-token"
+export DISCORD_CHANNEL_ID="your-channel-id"
+./watchdog.sh
+```
+
+## Managing the Service
+
+```bash
+sudo systemctl status openclaw-watchdog    # Check status
+sudo systemctl restart openclaw-watchdog   # Restart
+sudo systemctl stop openclaw-watchdog      # Stop
+tail -f ~/.openclaw/watchdog.log           # View logs
+```
