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.

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 | $0.00070 | $0.01481 |
| Opus 5 | $0.00035 | $0.00740 |
| Sonnet 5 | $0.00014 | $0.00296 |
| Haiku 4.5 | $0.00007 | $0.00148 |
Grade A, and why
home-network 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 6d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Home Network — find the layer before spending money
The defining mistake in home networking is buying hardware to fix a problem that was never in the hardware. A new router does nothing for a congested channel, a badly placed access point, a saturated uplink, or an ISP fault — and the user has spent real money and still has the problem. Your job is to locate the layer first. Everything else in this skill follows from that.
Detail lives in five references, each loaded at the step that needs it: diagnostics.md (the measurements and what the numbers mean), wifi-tuning.md (the free fixes, in order), router-buying.md (what to buy, and when not to), connecting-machines.md (sharing files, screens, printers between machines), and network-security.md (the hardening baseline).
The four layers, and how to tell them apart
| Layer | Symptom pattern | The isolating test |
|---|---|---|
| Device | One machine is slow; everything else on the same Wi-Fi is fine | Test a second device in the same spot. If it's fine, stop looking at the network |
| Wi-Fi | Slow or dropping the further you get from the router, fine beside it; worse in the evening | Compare a wired test to a Wi-Fi test at the router, then Wi-Fi at the problem spot |
| Router / LAN | All devices affected, everywhere, including wired; internal transfers slow too | Wired test at the router is also bad |
| ISP / uplink | All devices affected, wired included; the router's own status page shows the fault; often time-of-day | Wired speed test at the router is bad and the router reports a healthy LAN |
The single most useful measurement is a wired test at the router. If wired is fine and Wi-Fi is bad, the ISP is innocent and the fix is free. If wired is bad too, no amount of Wi-Fi tuning will help and no new router will either. Do this before any other diagnosis; it eliminates half the possibilities in ninety seconds.
The fix ladder — never skip a rung
Work strictly in order. Each rung is cheaper than the one after it, and roughly half of real complaints are solved by the first three.
What ships with it
5 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.

home-network is a skill published in the GitHub repository xiaolai/mac-it-guy-pro (5 stars, last pushed 1mo ago), licensed MIT. It adds 70 tokens to every session and 1,481 once invoked, about $0.0003 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 2026-08-31.
