Example 1: Build the thermostat status shortcut
User: "build the thermostat status shortcut"
→ BuildShortcut, authored through Skill("ComputerUse", "Drive") --app Shortcuts
→ "<prefix> Thermostat Status" exists, reads every thermostat through Home actions,
and `bun Tools/Shortcuts.ts run "<prefix> Thermostat Status"` returns
"Zone 1 21 heating, Zone 2 20 idle"
Example 2: A consumer runs a built shortcut
A home-control skill's thermostat script calls `shortcuts run "<prefix> Set Zone 1 Temp"`
with "21" on stdin → RunShortcut path → deterministic, no computer use
Example 3: Check what's there
User: "do my <prefix> shortcuts exist yet?"
→ ListShortcuts: bun Tools/Shortcuts.ts list | rg "<prefix>"
→ the matching names, or a plain "not built yet"
