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.
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
# Operator brief Make the operator understand the practical meaning of a complex technical finding and any decision it requires while preserving the technical finding as the evidence-bearing authority. ## Input Use the technical finding supplied in `$ARGUMENTS`, named by the user, or already established in the current task. Read the complete finding and any directly referenced material needed to interpret it. If the finding cannot be identified, ask for it rather than reconstructing one from hints. Do not edit the finding, its subject, or supporting artifacts unless the user separately asks for those changes. ## Write the brief Start with what happens, why it matters, or what the operator needs to decide. Keep conditions that control reachability, scope, impact, or confidence next to the claims they qualify. Keep each subject next to its verb: move a long qualifying phrase before the subject or after the object rather than between them, and put the shorter phrase first after a verb (rationale: [dependency locality supports ordering heuristics, not a reading-cost rule](../../theory/dependency-locality-supports-ordering-heuristics-not-a-reading-cost.md)).

How to install
mdr add zby/commonplace/operator-brief@sha256:6ea3f39195a97d35The line at the top of this page pins the label git:20261026.6360f0f, 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.
