What problem does it solve? Unexpected AWS billing spikes and idle resources often go unnoticed until the monthly invoice arrives. This Skill provides a structured workflow for detecting cost anomalies, identifying unused EC2 resources, and escalating findings before they become budget overruns. ## Core Features & Use Cases - Cost Anomaly Detection: Queries AWS Cost Explorer with aws ce get-cost-and-usage to compare daily spend against a baseline and flag spikes above a defined threshold. - Unused Resource Identification: Uses aws ec2 describe-instances to find instances idle beyond a set number of hours. - Safe Escalation Workflow: Defines explicit NEVER DO rules (no terminating instances, no modifying Reserved Instances) plus rollback and verification procedures. - Use Case: A FinOps engineer notices a 60% daily cost spike, runs the Skill in mock mode to diagnose whether a mismatched EC2 instance type caused it, and escalates with a documented report. ## Quick Start Ask the assistant to analyze daily AWS costs in your region for anomalies against the baseline using the configured EC2 instance and report any unused resources.
