Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, and the description does not disclose what constitutes validity (e.g., lat range -90 to 90, lon -180 to 180), return type (likely boolean), or edge cases. The description carries the full burden but fails to provide sufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
