Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description is the sole source for behavioral traits. It only states the data type ('Net in/out from CEXs') and a 'smart-money signal' tag, but does not disclose data freshness, update frequency, whether the operation is read-only, or any side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
