# Cost Anomaly Detector

Monitor cloud spending in near real time, detect abnormal spikes, and trigger alerts or safe remediation workflows before monthly bills explode.

## Problem
Cloud spend surprises are usually discovered days later in billing dashboards, after the costly behavior has already continued.

## Core capabilities
- Ingest billing and usage metrics from cloud providers.
- Learn baseline cost patterns by service, account, and environment.
- Detect anomalies using thresholds plus statistical deviation.
- Trigger response playbooks: alert only, scale-down, or shutdown non-critical resources.

## MVP scope
- AWS Cost Explorer integration first, then Azure/GCP.
- Daily anomaly scoring with high-priority instant alerts.
- Human approval required for any destructive remediation.

## Success criteria
- Faster detection of abnormal cost events.
- Measurable reduction in unplanned monthly overspend.

## Stretch ideas
- Forecast end-of-month bill scenarios with confidence ranges.
- Recommend reserved instances or savings plans automatically.
