Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description mentions 'real-time', hinting at live data, but does not elaborate on behavior such as polling frequency, data freshness, or any side effects. With no annotations, the description carries the full burden, but it only provides minimal context beyond the action of getting quotes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
