Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the transparency burden. 'VeChain is carbon-neutral!' adds a meaningful behavioral hint (likely returns zero or a neutrality status), but it does not disclose the output format, units, or data source. This is adequate for a simple read-only getter but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
