## Final String Widget Demo Workflow

This shows how to set up a workflow to test the final_string widget functionality:

```
┌─────────────┐    ┌─────────────────────────┐
│ Load Image  │    │ Gemini Image Describe   │
│             │────▶│                         │
│ [Load your  │    │ - API Key: [your key]   │
│  test image]│    │ - Model: gemini-2.5-    │
│             │    │   flash                 │
└─────────────┘    │ - System Prompt: [...]  │
                   │ - User Prompt: [...]    │
                   │                         │
                   │ ┌─────────────────────┐ │
                   │ │ final_string widget │ │  ← This widget auto-

                   │ └─────────────────────┘ │     execution!
                   └─────────────────────────┘
                                       │
                                       ▼
                         (Optional) connect `final_string`
                         to any built-in ComfyUI text display node
                         if you want it rendered outside the Gemini node.
```

### Step-by-step Instructions:

1. **Import the workflow**:
   - Copy the contents of `example_workflow.json`
   - In ComfyUI, go to "Load" → "Load (from file)" or drag the JSON file

2. **Set up the nodes**:
   - Load Image: Choose any test image
   - Gemini Image Describe: Enter your valid Gemini API key
   - (Optional) add a built-in ComfyUI text output node (e.g., `Text`/`Note`) and wire it to `final_string` if you want the caption outside of the Gemini panel

3. **Execute the workflow**:
   - Click "Queue Prompt" to run the workflow
   - Wait for the Gemini API to process the image

4. **Check the results**:
   - The `final_string` widget on the Gemini node should populate with generated text
   - Optional downstream text nodes should mirror the same string
   - Browser console should show "Updated final_string widget with:" message

### What was fixed:
- ❌ Before: final_string widget showed placeholder text
- ✅ After: final_string widget shows actual generated description

The widget update happens automatically when the node execution completes!
