operator-brief skillA

operator-brief is agent-read markdown (skill) from zby/commonplace: Explain an existing complex technical finding to an operator when its practical meaning is obscured by implementation detail, task-local terminology, or a long causal chain. Do not use for routine updates or simple answers..

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 zby/commonplace/operator-brief@git:20260829.73f530b

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.
