Prompt

Create a UiPath Flow project named "SubflowDemo" that takes a string input
called "text" and reverses it. The string reversal logic should be
encapsulated inside a subflow rather than done directly in the main flow.
Return the reversed string as an 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.

| **Flow input** | `text` (string, `direction: in`, bound to start trigger) |
| **Flow output** | `reversedText` (string, `direction: out`) — mapped from `$vars.reverseSubflow.output.reversed` on the End no
