Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01941 |
| Opus 5 | $0.00046 | $0.00971 |
| Sonnet 5 | $0.00018 | $0.00388 |
| Haiku 4.5 | $0.00009 | $0.00194 |
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.
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 — 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:
- Change defaults immediately — both the admin/login password and the WiFi password.
- Disable WPS — it's a brute-force surface.
- Disable UPnP unless an app genuinely needs it (it creates unpredictable port forwards).
- Use explicit port forwarding, never DMZ — DMZ exposes the entire device.
- Disable remote WAN admin access — use a VPN to manage remotely instead.
- Enable AiProtection (two-way IPS + malicious-site blocking) where available.
- Set up a guest network with intranet access disabled (proper isolation).
- Enable firewall logging for security monitoring; forward to syslog if you have a collector.
- Apply ingress filtering (BCP38/84 anti-spoofing) where supported.
- Keep firmware current — security fixes land in point releases.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

asus-router-ops is a skill published in the GitHub repository 0xDarkMatter/claude-mods (35 stars, last pushed 18d ago), licensed MIT. It adds 91 tokens to every session and 1,941 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
