Prompt
Create a flow called "MultiCityWeather". Loop over Seattle, Phoenix, and New York — for each city, fetch the current temperature from open-meteo (fahrenheit) and classify it as 'warm' (> 60F) or 'cold'. Output an array with all 3 results, each having the city name, temperature, and verdict. Do NOT run flow debug — just validate the flow. Do NOT ask for approval, confirmation, or feedback. Do NOT pause between planning and implementation. Build the complete flow end-to-end in a single pass. Before starting, load the uipath-maestro-flow skill. Read and follow its workflow steps exactly.
