## Workflow Generation Process

### Step 1: User Input
User describes the automation in natural language:
> "When I receive an email with a PDF attachment, extract the text using OCR, summarize it with AI, and post the summary to Slack"

### Step 2: AI Analysis
The selected AI model:
1. Parses the natural language request
2. Identifies required n8n nodes (Gmail, OCR, AI, Slack)
3. Determines node connections and data flow
4. Generates configuration for each node

### Step 3: Quality Validation
The workflow goes through:
- Node existence verification (683+ supported)
- Connection validation
- Configuration completeness check
- Best practices compliance

### Step 4: Output
Returns a complete n8n-compatible JSON workflow that can be:
- Executed directly in a8n's built-in engine
- Exported and imported into any n8n instance
- Customized using the visual editor
