Open every explanation with what the operator needs to do, and offer the answers

The operator could not tell from a notification whether to act, and was told to
have an agent do it. Each condition now says "Nothing for you to do." or
"Needs you:" with one thing they can do themselves, and carries the actions the
operator channel performs when chosen (hq ADR 0253).
