You are helping me build the following AI agent workflow.

## Goal
Extract Product Info from Website Screenshots: Adds a product URL to your sheet and Dumpling AI extracts name, price, discount, and rating from the screenshot.

## Specification
- What it does: Add a product URL to your Google Sheet, and Dumpling AI instantly extracts the name, price, discount, and rating from the website screenshot. This process captures visual data that traditional tools often miss, delivering structured information directly into your sheet for immediate analysis.
- Trigger: Triggered by an event (Event · on new row in Google Sheets)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Google Sheets: Store product URLs and store extracted results
  - Dumpling AI: Capture screenshots and extract visible product details via visual AI
  - HTTP Request: Communicate with external APIs for screenshot and extraction tasks

## Known pitfalls, handle each one explicitly in your implementation
1. Google Sheets has row limits for API writes, so batch updates or use a queue if processing large volumes of URLs simultaneously.
2. Anti-bot measures might block Dumpling AI's headless browser, so rotate user agents or use proxy services to maintain consistent capture success.

## Reference implementation
https://n8n.io/workflows/5169 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
