You are helping me build the following AI agent workflow.

## Goal
URL Screenshot Capture and Notification: When a new spreadsheet lands in your Drive folder, it captures screenshots of every URL listed and emails you the link to the results.

## Specification
- What it does: Get instant email notifications whenever new spreadsheets arrive in your Drive folder, featuring screenshots of every URL listed inside them. You'll receive a direct link to view these visual snapshots without needing to manually check the files yourself.
- Trigger: Triggered by an event (Event · on new spreadsheet in Google Drive folder)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Google Sheets: Extract URLs from spreadsheet column
  - HTTP Request: Call ScreenshotOne API to capture images
  - Google Drive: Store captured screenshots and trigger workflow
  - Gmail: Send notification email with folder link

## Known pitfalls, handle each one explicitly in your implementation
1. Large image files may exceed Gmail attachment size limits so consider uploading images directly to Drive and sharing the link instead of attaching them.
2. Invalid or malformed URLs in the spreadsheet will cause the HTTP request to fail so add input validation before making the API call.
3. Google Drive folder permissions might prevent the automation service account from saving files so ensure the service account has editor access to the target folder.

## Reference implementation
https://n8n.io/workflows/3321 (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.
