About the project

OpenClaw is an AI assistant that runs on a user's own devices and connects to chat services such as Discord, Slack, Telegram, and WhatsApp. Individuals or teams use it for assistant tasks while keeping its state, memory, and credentials on their hardware and choosing the models or agent harnesses it uses. The catalogue entries are skills, agents, instructions, hooks, and settings that define or extend OpenClaw's workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

healthcheck scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenClaw host healthcheck

Goal: assess host risk, run read-only checks, then propose staged hardening without breaking access.

Rules

  • Ask before state-changing actions.
  • Do not change SSH/firewall/remote access until access path is confirmed.
  • Prefer reversible steps and rollback notes.
  • Never claim OpenClaw manages OS firewall, SSH, or updates.
  • If identity/role unknown, recommend only.
  • User choices: numbered list.
  • Never print secrets.

Context to infer first

  • OS/version, container vs host.
  • Privilege level.
  • Access path: local, SSH, RDP, tailnet.
  • Network exposure: public IP, reverse proxy, tunnel, LAN only.
  • OpenClaw gateway status, bind, auth.
  • Backup status.
  • Disk encryption.
  • Automatic security updates.
  • Usage mode: personal workstation, local assistant box, remote server, other.

Ask only for missing facts. Simple phrasing preferred.

Read-only checks

Ask once for permission to run read-only checks. Then run relevant commands.

Common:

openclaw security audit --deep
openclaw gateway status --deep
openclaw doctor --lint

doctor --lint can exit 1 for findings: read the report and continue the remaining checks. Ordinary doctor and doctor --non-interactive can copy legacy config and migrate state without --fix; reserve repairs for explicit approval. Read-only checks exclude config/service repairs and state migrations, but may produce incidental logs or cache bookkeeping.

macOS:

sw_vers
lsof -nP -iTCP -sTCP:LISTEN
/usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate
pfctl -s info
tmutil status
fdesetup status
softwareupdate --schedule

Linux:

cat /etc/os-release
ss -ltnup || ss -ltnp
ufw status || firewall-cmd --state || nft list ruleset
systemctl status ssh sshd
lsblk -f

Windows:

systeminfo
Get-NetFirewallProfile
Get-BitLockerVolume

Risk profile

After context is known, ask desired posture:

  1. Convenience: local/private, minimal prompts.
  2. Balanced: secure defaults, low friction.
  3. Strict: remote/public/sensitive data, more lock-down.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
