Overview

The point of categorizing transactions is to see, every month, what changed. This skill computes the comparative numbers — current vs. rolling, current vs. budget, current vs. same-month-last-year — for every category, identifies outliers, and surfaces the transactions that drive them. It refuses to flag noise: small categories below a materiality floor are excluded.
