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).
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/.
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.
