Analyze resource utilization patterns to identify waste and produce rightsizing recommendations. Use this skill whenever the user mentions cost optimization, rightsizing, idle resources, reserved instance, savings plan, waste, utilization, or is working with AWS Cost Explorer, Kubecost, FinOps, even if they never say "infrastructure cost optimization" explicitly. Routes live lookups through the Infrastructure-Cost-Optimizer-Plugin endpoint. Do not use it for unrelated application feature work or general coding questions.
