Scored across 5 tools
Each tool serves a distinct weather data purpose: historical, hourly forecast, realtime, alerts, and weekly forecast. There is no overlap in functionality.
All tools follow the consistent 'get_<descriptor>_weather' or 'get_<forecast_type>' pattern, providing a clear and predictable naming convention.
5 tools is an appropriate number for a weather API, covering the most common weather data needs without being excessive or insufficient.
The tool set covers realtime, historical, hourly forecast, weekly forecast, and alerts. Missing extended forecasts or additional weather parameters, but the core domain is well-covered.
