About this skill
About KPI drop investigator
When a key number drops overnight, everyone has a theory and nobody has a method. This skill investigates in the right order: first ruling out data problems such as tracking changes, pipeline delays or definition changes, then breaking the metric into its components and segmenting by platform, country, channel, app version and new versus returning users. It ranks the likely causes and gives the query to confirm each. Following it stops teams from 'fixing' a drop that was really a broken event. To use it, paste the skill into your assistant and send the metric, how much it changed, when, and any data you have by segment; the reply opens with “Is it real?”.
