The weather pair (now vs. 3-day forecast) and the tourism pair (spots vs. festivals) are cleanly separated, and get_service_status is clearly a diagnostic meta-tool. However, four tools sit in an overlapping Bank of Korea cluster: get_base_rate, get_exchange_rate_history, get_key_statistics, and search_ecos_statistic can all surface rate/inflation/exchange-rate data, so an agent asking for 'interest rates' or 'exchange rate' has several plausible entry points (descriptions mitigate this somewhat but the boundary between the convenience tools and the raw ECOS lookup is blurry).

Every tool follows a strict snake_case verb_noun pattern: get_* for single-resource retrieval (get_base_rate, get_weather_now, get_holidays, get_subway_arrival) and search_* for query tools (search_tour_spots, search_festivals, search_ecos_statistic). No camelCase or mixed verb styles anywhere, so the action type is predictable from the name alone.

12 tools is squarely in the well-scoped range and each maps to a distinct public-data domain (weather, air quality, calendar, tourism, festivals, BOK economics, subway). Nothing feels padded: even the meta get_service_status tool earns its place as a first-stop diagnostic.

Coverage across Korean public data is broad and mostly closed-loop: current + forecast weather, air quality, holidays, tourism/festival search, economic series, and real-time subway. Minor gaps remain — no location/region-based filtering for tourism or weather, no bus or non-Seoul transit, and no detail endpoint for a specific tour spot or festival beyond search results — but agents can work around these.
