name: healthcheck description: Host security hardening and risk-tolerance configuration for OpenClaw deployments. Use when a user asks for security audits, firewall/SSH/update hardening, risk posture, exposure review, OpenClaw cron scheduling for periodic checks, or version status checks on a machine running OpenClaw (laptop, workstation, Pi, VPS).

OpenClaw Host Hardening

Overview

Assess and harden the host running OpenClaw, then align it to a user-defined risk tolerance without breaking access. Use OpenClaw security tooling as a first-class signal, but treat OS hardening as a separate, explicit set of steps.

Core rules

• Recommend running this skill with a state-of-the-art model (e.g., Opus 4.5, GPT 5.2+). The agent should self-check the current model and suggest switching if below that level; do not block execution.
• Require explicit approval before any state-changing action.
• Do not modify remote access settings without confirming how the user connects.
• Prefer reversible, staged changes with a rollback plan.
• Never claim OpenClaw changes the host firewall, SSH, or OS updates; it does not.
• If role/identity is unknown, provide recommendations only.
• Formatting: every set of user choices must be numbered so the user can reply with a single digit.
• System-level backups are recommended; try to verify status.

Workflow (follow in order)

0) Model self-check (non-blocking)

Before starting, check the current model. If it is below state-of-the-art (e.g., Opus 4.5, GPT 5.2+), recommend switching. Do not block execution.

1) Establish context (read-only)

Try to infer 1–5 from the environment before asking. Prefer simple, non-technical questions if you need confirmation.

Determine (in order):

1. OS and version (Linux/macOS/Windows), container vs host.
2. Privilege level (root/admin vs user).
3. Access path (local console, SSH, RDP, tailnet).
4. Network exposure (public IP, reverse proxy, tunnel).
5. OpenClaw gateway status and bind address.
6. Backup system and status (e.g., Time Machine, system images, snapshots).
7. Deployment context (local mac app, headless gateway host, remote gateway, container/CI).
8. Disk encryption status (FileVault/LUKS/BitLocker).
9. OS automatic security updates status. Note: these are not blocking items, but are highly recommended, especially if OpenClaw can access sensitive data.
10. Usage mode for a personal assistant with full access (local workstation vs headless/remote vs other).

First ask once for permission to run read-only checks. If granted, run them by default and only ask questions for items you cannot infer or verify. Do not ask for information already visible in runtime or command output. Keep the permission ask as a single sentence, and list follow-up info needed as an unordered list (not numbered) unless you are presenting selectable choices.

If you must ask, use non-technical prompts:

• “Are you using a Mac, Windows PC, or Linux?”
• “Are you logged in directly on the machine, or connecting from another computer?”
• “Is this machine reachable from the public internet, or only on your home/network?”
• “Do you have backups enabled (e.g., Time Machine), and are they current?”
• “Is disk encryption turned on (FileVault/BitLocker/LUKS)?”
• “Are automatic security updates enabled?”
• “How do you use this machine?” Examples:
  • Personal machine shared with the assistant
  • Dedicated local machine for the assistant
  • Dedicated remote machine/server accessed remotely (always on)
  • Something else?

Only ask for the risk profile after system context is known.

If the user grants read-only permission, run the OS-appropriate checks by default. If not, offer them (numbered). Examples:

1. OS: uname -a, sw_vers, cat /etc/os-release.
2. Listening ports:
   • Linux: ss -ltnup (or ss -ltnp if -u unsupported).
   • macOS: lsof -nP -iTCP -sTCP:LISTEN.
3. Firewall status:
   • Linux: ufw status, firewall-cmd --state, nft list ruleset (pick what is installed).
   • macOS: /usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate and pfctl -s info.
4. Backups (macOS): tmutil status (if Time Machine is used).

2) Run OpenClaw security audits (read-only)

As part of the default read-only checks, run openclaw security audit --deep. Only offer alternatives if the user requests them:

1. openclaw security audit (faster, non-probing)
2. openclaw security audit --json (structured output)

Offer to apply OpenClaw safe defaults (numbered):

1. openclaw security audit --fix

Be explicit that --fix only tightens OpenClaw defaults and file permissions. It does not change host firewall, SSH, or OS update policies.

If browser control is enabled, recommend that 2FA be enabled on all important accounts, with hardware keys preferred and SMS not sufficient.

3) Check OpenClaw version/update status (read-only)

As part of the default read-only checks, run openclaw update status.
