billing-posting-clerk skillA

billing-posting-clerk is agent-read markdown (skill) from wonsukchoi/domain-experts: Use when a task needs the judgment of a billing and posting clerk — generating an invoice against a rate/contract schedule, applying an incoming payment across multiple open invoices, processing a credit memo or adjustment, or investigating an aging-report discrepancy..

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.

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.
