Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says the endpoint returns grass seasons; it does not mention output format, whether the countryId filters results, or any edge cases. The GET method implies read-only, but the description adds almost no behavioral depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
