Diagnose whether the most important idea in an article, essay, post, memo, section, paragraph, or sentence appears where it best serves the reader. Use for BLUF checks, buried or misplaced ledes, slow or misleading openings, intro drift, competing main ideas, and requests to get to the point or find the real opening. Compare what the opening foregrounds with what the artifact actually delivers, judge whether any delay is earned, and recommend the smallest structural move. Diagnose by default; rewrite only when asked.
