asus-router-ops

asus-router-ops is a skill for Claude Code from 0xDarkMatter/claude-mods. It costs 91 tokens per session (1,941 once invoked), scanned A, original, MIT.

An operations guide for configuring and securing ASUS routers, including standard Asuswrt firmware and the community Asuswrt-Merlin version. It covers network access, DNS, VPNs, mesh systems, and separating smart-home devices from other devices.

In plain words
What is it for?
Use it to configure encrypted DNS, WireGuard or OpenVPN, guest and IoT isolation, AiMesh, AiProtection, Merlin scripts, and related router settings.
Why use it?
It helps reduce security and connectivity mistakes when changing router settings that could expose devices or lock you out of the network.

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

asus-router-ops 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (assets/firewall-start.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ASUS Router Operations

Facts verified as of 2026-07.

Authoritative guidance for configuring and hardening ASUS routers — stock Asuswrt and Asuswrt-Merlin firmware — via the web UI and SSH/nvram. Covers security hardening, encrypted DNS, VPN, network segmentation, AiMesh, AiProtection, and JFFS scripting.

Safety first. Changes here can lock you out or drop the network. Test during low-usage windows, document the before value, and know how to undo. Cite official docs, not folklore.


Stock Asuswrt vs Asuswrt-Merlin

Stock Asuswrt Asuswrt-Merlin
Base ASUS official Community fork of ASUS source (same core, more control)
Scripting Limited JFFS custom scripts, cron, services-start, firewall-start, nat-start
DNS control Basic DNS Director (per-client/global DNS redirection, DoT)
VPN OpenVPN/WireGuard server+client + VPN Director (policy/split-tunnel routing)
Best for Most users Power users wanting scripts, fine-grained DNS/VPN routing

Never mix stock and Merlin nodes in the same AiMesh network. Keep the firmware family consistent across mesh nodes.


Security hardening checklist

Do these on every new router, in order:

  1. Change defaults immediately — both the admin/login password and the WiFi password.
  2. Disable WPS — it's a brute-force surface.
  3. Disable UPnP unless an app genuinely needs it (it creates unpredictable port forwards).
  4. Use explicit port forwarding, never DMZ — DMZ exposes the entire device.
  5. Disable remote WAN admin access — use a VPN to manage remotely instead.
  6. Enable AiProtection (two-way IPS + malicious-site blocking) where available.
  7. Set up a guest network with intranet access disabled (proper isolation).
  8. Enable firewall logging for security monitoring; forward to syslog if you have a collector.
  9. Apply ingress filtering (BCP38/84 anti-spoofing) where supported.
  10. Keep firmware current — security fixes land in point releases.

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.
