Term interrogation

A reader who nods along and learns nothing has been failed by the writing, not by their own attention. The words that cause it are rarely the difficult ones. Difficult words announce themselves and get looked up. The dangerous words are the ordinary-sounding ones that carry a whole concept quietly inside them.

"The company built a moat around its core workflow." Every word there is common English. The sentence is still unreadable, because "moat" is standing in for an argument about why competitors cannot take these customers away, and that argument was never made.

This skill finds those words and makes them explain themselves.

What this skill is for, and what it is not

It runs after a draft exists. It is an audit and repair pass over finished prose, not a drafting style.
