You are helping me build the following AI agent workflow.

## Goal
YouTube Subscription Notifications: Every hour, checks your subscribed YouTube channels for new videos and emails you a notification with a clickable thumbnail link.

## Specification
- What it does: Get notified via email whenever your subscribed YouTube channels upload new videos, complete with a clickable thumbnail link. This automated check happens every hour so you never miss an update without manually refreshing your feeds.
- Trigger: On a schedule (Scheduled · every hour)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - YouTube: Fetch subscriptions and latest videos via API and RSS
  - HTTP Request: Retrieve video data from RSS feeds
  - Send Email: Deliver notifications for new videos

## Known pitfalls, handle each one explicitly in your implementation
1. RSS feeds may not include all video types like Shorts or Premieres, so add filters to exclude non-standard content if needed.
2. Email providers often block automated emails with large images, so use direct thumbnail URLs rather than embedding base64 data.

## Reference implementation
https://n8n.io/workflows/3216 (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.
