Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It simply states 'List withholding tax rates' without indicating pagination, result format, read-only nature, or any side effects. While listing implies a read operation, the description does not explicitly confirm safety or explain behavior beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
