SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill centralizes Azure cost management tasks so users can query historical spending, forecast future bills, and identify savings opportunities without manually assembling Cost Management API calls or cross-referencing multiple data sources.

Core Features & Use Cases

  • Cost Querying & Reporting: Retrieve historical costs and break down spend by subscription, resource group, service, tag, or resource to produce detailed billing reports.
  • Forecasting & Trends: Project end-of-month and future spending using Cost Management forecast APIs and surface trend analysis and anomalies.
  • Optimization & Rightsizing: Detect orphaned or underutilized resources, run AKS/Redis-specific checks, and produce actionable rightsizing and cost-reduction recommendations; for example, generate a report that highlights top cost drivers and suggested VM size changes to save monthly costs.

Quick Start

Show me the last 30 days of Azure costs for subscription 12345678-1234-1234-1234-123456789012 broken down by service and resource group.
