Securing Your AI: A Comprehensive Guide to the OpenClaw Healthcheck Skill

With great power comes great responsibility. OpenClaw agents often have unrestricted access to your file system, shell, and personal data. Ensuring the host machine is secure is not just optional—it's critical.

Enter the Healthcheck skill.

Designed by security experts, the Healthcheck skill provides a comprehensive audit of your OpenClaw host environment, identifying risks and recommending hardening measures.

What Does Healthcheck Audit?

When you run a healthcheck, the agent scans several key vectors:

1. SSH Configuration: Checks if root login is disabled, if password authentication is off, and if SSH keys are being used securely.
2. Firewall Status: Verifies if a firewall (like UFW or pf) is active and configured.
3. System Updates: Scans for pending security updates or outdated packages.
4. Open Ports: Identifies potentially dangerous exposed ports.
5. Risk Posture: Calculates an overall risk score based on your configuration.

How to Run a Healthcheck

Using the skill is simple. In your OpenClaw session, just ask:

"Run a healthcheck."

Or be more specific:

"Audit my system security and tell me the risks."

The agent will execute the audit script and return a summarized report with a pass/fail status for each check.

Automating Security with Cron

Security isn't a one-time task. To stay secure, you should run these checks regularly. You can use OpenClaw's Cron feature to schedule this.

Setting up a Weekly Audit

You can ask OpenClaw to set this up for you:

"Schedule a weekly security healthcheck for Monday morning at 9 AM."

Under the hood, this creates a cron job:

{
  "name": "weekly-healthcheck",
  "schedule": { "kind": "cron", "expr": "0 9 * * 1" },
  "payload": {
    "kind": "agentTurn",
    "message": "Run a full system healthcheck and report any new vulnerabilities."
  }
}

Interpreting the Results

The report uses a simple traffic light system:

• 🟢 PASS: Configuration meets security best practices.
• 🟡 WARN: Non-critical issue (e.g., uptime is high, verify patches).
• 🔴 FAIL: Critical risk (e.g., SSH root login enabled).

If you see a FAIL, the agent will often provide the exact command needed to fix it. Always review these commands before asking the agent to execute them.

Conclusion

Your AI assistant is part of your infrastructure. Treat it with the same security rigor as a production server. By using the Healthcheck skill, you ensure that OpenClaw remains a helpful assistant, not a security liability.

Stay safe, and happy coding!
