# Azure Cost Optimization

## Quick Reference

| Intent | Workflow | Primary tools |
|--------|----------|---------------|
| 減少浪費或 rightsize | [Optimization](references/optimization.md) | Cost and Resource Graph tools |
| 檢視 commitment | [Commitments](references/commitments.md) | `list_benefit_utilization`, `list_reservation_transactions`, `get_benefit_recommendations` |

## When to Use This Skill

用在浪費、rightsizing 和 commitment。

## MCP Tools

最佳化用成本工具和 Resource Graph 工具，commitment 用 benefit 工具。
查詢要先驗證。Fallback：[API mappings](references/tool-fallback.md)。

## Workflow

1. 確認 scope、期間、幣別和 commitment 的意圖。
2. 只載入上面對應的那個 workflow。
3. 絕對不要在 shell 或 interpreter 裡轉換 MCP 的結果；要經過驗證的
   伺服器端投影、聚合或有範圍限制的後續查詢，請在工具那邊做。
4. 把實測成本、回報的節省金額和定性的改善機會分開講。
5. 只提出建議；不要刪除、調整大小、購買或部署任何資源。

## Error Handling

| Error | Action |
|-------|--------|
| Access denied | 說出 scope 和權限。 |
| Multiple currencies | 依幣別分組，每種幣別分開回報。 |
| Missing evidence | 說明缺口；不要編造數值。 |
| Server error | 重試一次；還是失敗就回報 trace ID。 |

# Azure Cost Optimization

## Quick Reference

| Intent | Workflow | Primary tools |
|--------|----------|---------------|
| Reduce waste or rightsize | [Optimization](references/optimization.md) | Cost and Resource Graph tools |
| Review commitments | [Commitments](references/commitments.md) | `list_benefit_utilization`, `list_reservation_transactions`, `get_benefit_recommendations` |

## When to Use This Skill

Use for waste, rightsizing, and commitments.

## MCP Tools

Use cost and Resource Graph tools for optimization and benefit tools for
commitments. Validate queries. Fallback: [API mappings](references/tool-fallback.md).

## Workflow

1. Confirm scope, period, currency, and commitment intent.
2. Load only the matching workflow above.
3. Never transform MCP results in a shell or interpreter; request validated
   server-side projection, aggregation, or bounded follow-up queries.
4. Separate measured cost, reported savings, and qualitative opportunities.
5. Recommend changes only; do not delete, resize, purchase, or deploy resources.

## Error Handling

| Error | Action |
|-------|--------|
| Access denied | Name the scope and permission. |
| Multiple currencies | Group and report each currency separately. |
| Missing evidence | State the gap; do not invent values. |
| Server error | Retry once; then report the trace ID. |
