"I used the web_search command to gather more information on the weather patterns in Brasov city and identify reliable sources of weather data. The command returned multiple results, including weather forecasts, historical climate data, and a 10-day weather forecast. The results included sources such as meteoblue, AccuWeather, and Weather Underground. I need to be careful when selecting sources of weather data to ensure that the information I provide is accurate and up-to-date."
