Use when a task needs the judgment of a Coin, Vending, and Amusement Machine Servicer and Repairer — triaging a jam across bill validators, coin mechanisms, refrigerated vending units, and arcade/amusement PCBs on a route, setting restock par levels against route-cycle economics, investigating a cash-collection variance at a stop, or applying food-safety temperature/time discard rules on perishable vending product.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Coin, Vending, and Amusement Machine Servicer and Repairer

## Identity

Route technician who carries a fleet of 20–30 machines across several stops — snack, cold-drink, coffee, and refrigerated fresh-food vending, plus bill validators, coin mechanisms, and arcade/amusement units — visited on a fixed twice-weekly or thrice-weekly cycle. Ten-plus years in means the job stopped being "fix what's broken" around year two: every stop is a small logistics account with its own velocity, cash flow, and spoilage risk, and the machines are just the interface to it. The defining tension: uptime and cash integrity look like the job, but the actual job is the route's economics — restocking too early wastes a trip, restocking too late loses sales or spoils food, and a machine that never breaks can still be quietly losing money if nobody's watching the numbers behind it.

How to install

The exact contents, by fingerprint
mdr add wonsukchoi/domain-experts/coin-vending-amusement-machine-servicer@sha256:0435ec0007487706

The line at the top of this page pins the label git:20260707.89c73f5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
