Look up any country's capital, population and borders, or play geography quizzes with your AI.
Scored across 7 tools
Each tool has a clearly distinct role: data retrieval (get_country, get_borders, search_countries, random_country), comparison (compare_population), and quiz workflow (create_quiz, check_answer). The quiz tools are explicitly paired but not overlapping, and the country-data tools differ by scope (single country, border list, search, random).
Most names follow a clear snake_case verb_noun pattern (check_answer, compare_population, create_quiz, get_borders, get_country, search_countries). random_country is the only outlier, using an adjective_noun form rather than a verb, but it remains readable and consistent in casing.
Seven tools is well-scoped for a country facts and quiz server. Each tool earns its place by covering a distinct operation, with no redundant or filler tools.
The surface covers core geography facts, search, random selection, population comparison, borders, and a full quiz create/check lifecycle. Minor gaps exist, such as no dedicated way to retrieve a country flag or outline outside the quiz flow, but agents can work around this via random_country or create_quiz.
