UserYour personal IT guy for macOS — remembers your machine, guards every action, explains what it did, and leaves reusable tools behind. A plugin for Claude Code and Codex, for people who are not programmers.

mac-it-guy
Use when the user wants help looking after their Mac — a health checkup, reclaiming disk space, organising files, diagnosing a problem in plain language, setting up backups, fixing Wi-Fi or a home network, automating a repetitive chore, or understanding what just happened. Also the entry point when the user types _it or the IT guy's name with a leading underscore. Routes to the right workflow, loads the binding safety contract first, and never treats a diagnosis as permission to act.
home-network
Decision logic for home network work — isolating whether a problem is the device, the Wi-Fi, the router, or the ISP before spending money; the fix ladder from free to hardware; router and mesh buying judgement; and the boundaries of whose network may be touched. Load before any /mac-it-guy-pro:network work.
it-core
Core conventions for all mac-it-guy-pro commands and agents — the safety contract, plain-language rules, report formats, and state file layout. Load before any IT task (checkup, cleanup, organize, fix, automate, backup, onboard).
machine-profile
How the IT guy remembers, refreshes, and retires what it knows about this machine — the profile schema, provenance classes, expiry by evidence, the belief ledger, demotion to history, the visit log, and undo manifests. Load when reading, writing, reviewing, or pruning anything in ~/ITGuy/.
macos-recipes
Exact macOS commands for IT diagnostics and safe actions — disk, memory, startup items, updates, Time Machine, battery, SMART, duplicate detection, Trash-based deletion, HEIC conversion, photo dates, launchd scheduling. Load before running any diagnostic or maintenance command on a Mac.
open-internet
Decision logic for building a personal unrestricted-internet connection from a censored network — which architecture to use (CDN-fronted vs direct), which protocols work and which are detectable, and the boundaries of what to help with. Load before any /mac-it-guy-pro:open-internet work.
toolbox-contract
The micro-product contract for the IT Guy toolbox — acceptance criteria, directory layout, README template, registry schema, dry-run requirement, double-clickable wrappers, the evolution ladder, and the pattern catalogue used to offer a user automations they did not know to ask for. Load when building, listing, running, evolving, or removing tools in ~/ITGuy/toolbox/, or when deciding whether to suggest one.
tutoring
How the IT guy explains rather than just fixes — the two teaching modes (just-in-time and deliberate study), the learning-map structure, grounding lessons in the user's own measurements, depth scaling, and the pull-not-push rule. Load before any /mac-it-guy-pro:learn work or when a user asks why something was the fix.
