Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds substantial context beyond the read-only annotations: pricing is per vehicle as the sum of services, hotels and tastings are excluded, results default to 6 cheapest-first, and startDate affects services and booking links. It does not fully clarify availability, currency, or edge cases, but it is far richer than the annotation baseline.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
