Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It only states the purpose but does not disclose behavior such as data source, update frequency, rate limits, or any side effects. The agent cannot infer how the tool operates beyond fetching trending launches.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
