Pulls AWS Cost Explorer data and scans your account for the usual suspects: unattached EBS volumes, unused Elastic IPs, idle EC2 instances, old snapshots. It's read-only analysis by default, which keeps risk low, but you'll need to manually act on the recommendations or write your own deletion scripts. The workflow is sensible: baseline your spending, grab quick wins like releasing unused IPs, then tackle strategic stuff like Reserved Instance coverage. Most useful when you've got cost creep and need someone to systematically check CloudWatch metrics and usage patterns across services. It's not going to automatically fix anything, but it'll surface the waste you forgot about.
