Prompt

Move getWeather and formatSummary into a subflow called "fetchAndFormat". The subflow should output the temperatureF value. The rest of the main flow (decision + end nodes) stays but reads from the subflow output.

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.
