What it does

This workflow watches for fresh billing data loads and, on each one, evaluates the most recent hour of cloud spend against a statistical baseline using a Z-score. When the latest hour is a clear statistical outlier, it fires an urgent narrated alert to Discord within minutes rather than waiting for a daily report.

When to use it

Use it for runaway-cost protection: a misconfigured autoscaler, a forgotten large query job, or a leaked credential mining compute. Daily digests catch slow drift; this catches the fast, expensive incidents while you can still stop them.

How it works

  1. 1A webhook trigger fires when a new BigQuery billing-export load completes.
  2. 2A BigQuery query computes the latest hour's spend plus the mean and standard deviation over the prior 7 days of the same hour.
  3. 3A logic step calculates the Z-score and continues only if it exceeds the alert threshold.
  4. 4OpenAI drafts a tight incident message naming the spiking service, the dollar figure, and the deviation magnitude.
  5. 5The alert posts to the finance Discord channel with an at-here mention so it surfaces immediately.
