+## OpenClaw Automated Self-Healing Engine
+
+Included in this repository is `openclaw-healer.sh`, a robust background daemon script designed to mitigate headless browser crashes and port deadlocks commonly encountered when automating OpenClaw or Puppeteer.
+
+### What it does:
+1. **Zombie Reaping:** Continuously scans for and aggressively reaps `[Z] Defunct` instances of Chrome, Chromium, and Puppeteer by terminating their deadlocked parent processes.
+2. **Port Mitigation:** Monitors target ports (default `18800`) for stalled processes. If a process holds the port for longer than 120 seconds, the healer executes a forced termination (`kill -15` then `kill -9`) to guarantee the port is released for the next automation task.
+
+### How to run it:
+```bash
+chmod +x openclaw-healer.sh
+nohup bash -c "while true; do ./openclaw-healer.sh; sleep 60; done" > /var/log/openclaw-healer.log 2>&1 &
+```
