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 | $0.00073 | $0.01684 |
| Opus 5 | $0.00036 | $0.00842 |
| Sonnet 5 | $0.00015 | $0.00337 |
| Haiku 4.5 | $0.00007 | $0.00168 |
Grade A, and why
tutoring 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 5d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tutoring — build the model, not the procedure
Scope note
This skill governs how to teach — the modes, the grounding rule, the ten-section structure, depth scaling, and the pull-not-push discipline. It holds no domain facts of its own.
The subject matter comes from the companions and should be read there rather than recalled: mac-it-guy-pro:home-network for Wi-Fi and LAN, mac-it-guy-pro:open-internet for access and protocols, mac-it-guy-pro:macos-recipes for machine mechanics, mac-it-guy-pro:it-core for the safety principles worth teaching as principles, and mac-it-guy-pro:toolbox-contract for automation. Where those files record uncertainty, this skill requires that the uncertainty be taught too.
Assume the operational work is done for the user. They do not need to memorise commands, menus, or syntax. The goal is a mental model that lets them decide — when to worry, what to check first, what to buy, what to ignore, and what to automate next. That last one is the only part no assistant can do for them.
The asset no generic course has
The IT guy just did the thing, on this machine, with these numbers. A user who has just watched their loaded responsiveness measured at 180 RPM while a download runs is ready to understand bufferbloat in a way no textbook opening can match — they have the symptom, the measurement, and the fix in hand at the same moment.
So every lesson is grounded in the user's own evidence: values from ~/ITGuy/machine.md, events from ledger.jsonl, and what actually happened in visits.log. Quote their real numbers. Reach for a generic example only when their machine has no instance of the thing, and say that you are doing so.
Two modes, and they are not equal
Just-in-time is the one that matters for a non-technical user. Something just happened; explain why, in a paragraph, right then. No diagrams, no sections, no reading assignment. This mode is triggered by the user asking "why?", by /mac-it-guy-pro:learn why, or by a genuinely surprising finding — never by a routine one.
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.

tutoring is a skill published in the GitHub repository xiaolai/mac-it-guy-pro (5 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 1,684 once invoked, about $0.0004 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.
