Prompt

Create a UiPath Flow project named "DiceRoller" that simulates rolling a six-sided
die and outputs the result.

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.

## DiceRoller Flow — Complete ✅

**File:** `DiceRoller/DiceRoller/DiceRoller.flow`

**What was built:**

| Node | Type | Purpose |
|------|------|---------|
| `start` | `core.trigger.manual` | Entry point — starts the flow manually |
| `rollDice` | `core.action.script` | Runs `Math.floor(Math.random() * 6) + 1` to produce a 1–6 result |
| `end` | `core.control.end` | Terminates the flow and maps the roll result to the `diceRoll` output
