Use when users ask about Aliyun or Tencent Cloud costs, bills, spending, charges, 账单, 费用, 成本, billing trends, month-by-month changes, category breakdowns, or resource-level attribution. Default providers are Aliyun and Tencent Cloud. Supports validating CLI auth, pulling recent monthly summaries, normalizing service categories, and drilling down into resource evidence when attribution matters.
