Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses the most important behavioral fact — 'Alias tương thích' (compatible alias) means this tool behaves identically to cloud_prices. But it provides nothing beyond that: no indication of what the operation does, no read-only/mutation hints, no auth or output-format info, forcing the agent to dereference cloud_prices for actual behavior. Useful but thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
