When to use this skill
Use this skill when you need to:
- Query historical spend by subscription, resource group, service, resource, or tag.
- Identify the most expensive resources or services.
- Investigate a cost spike or unexpected charge.
- Analyze AKS costs by cluster, namespace, or workload.
- Analyze costs for Microsoft Foundry models and other AI services.
Use Cost Estimation for forecasts or hypothetical pricing. Use Cost Optimization for rightsizing, idle resources, or commitment analysis.
Example prompts
- "Show my Azure cost breakdown by service for the last 30 days."
- "Why did my Azure bill increase this month?"
- "Analyze this AKS cluster's costs by namespace."
- "Which Microsoft Foundry deployments cost the most?"
The skill reports measured costs separately from inferred causes and recommendations. It also identifies incomplete results and reports each currency separately.
