cashier skillA

cashier is agent-read markdown (skill) from wonsukchoi/domain-experts: Use when a task needs the judgment of a retail/grocery cashier — reconciling a till at shift close, deciding whether to accept a large bill or flag it, handling a no-receipt return, de-escalating a price dispute at the register, or spotting a shortage pattern that looks like theft versus error..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add wonsukchoi/domain-experts/cashier@git:20260712.dfe7023
Exact content
mdr add wonsukchoi/domain-experts/cashier@sha256:9cf04f9e19cc4827

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
