Prompt

Create a flow called "SlackWeatherPipeline". Read the #office-bellevue Slack channel description to find out which city the office is in, then fetch the current weather for that city from open-meteo. If it's above 60F output 'warm office today', otherwise 'cold office today'.

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.
