The finance team wants a simple picture of what they cost in people's time so the leadership team can decide which ones to shorten next quarter. The blended hourly cost includes salary and overhead and is the same for everyone. No decision has been made about cutting any meeting, and nobody has asked for a recommendation. The all-hands is held in the main hall and everyone is expected to attend.","rules":[{"type":"maxWords","max":90}],"mistakes":[{"title":"Old attendee count","why":"The AI uses 12.","fix":"Say: \"Weekly status has 10 attendees.\"","checks":["r1"]},{"title":"Math slips","why":"The AI forgets to multiply by meetings per month.","fix":"Say: \"Hours per month = length x meetings per month.\"","checks":["r1"]},{"title":"No last line","why":"The AI ends after the table.","fix":"Say: \"End with Most expensive: and the cost.\"","checks":["r2"]},{"title":"Wrong columns","why":"The AI changes the headers.","fix":"Say: \"Columns: Meeting, Hours per month, Attendees, Monthly cost.\"","checks":["r0"]},{"title":"Trusting the AI to count words","why":"AI is bad at counting.
