You are helping me build the following AI agent workflow.

## Goal
YouTube Video Scheduling & AI Metadata Generation: Daily automation that extracts transcripts via Apify, generates SEO metadata with OpenAI, and schedules private videos for publication.

## Specification
- What it does: You get your YouTube videos ready for publication automatically by having transcripts extracted via Apify and SEO-optimized descriptions generated with OpenAI. The workflow then updates the metadata and schedules each video to go live at strategic times while keeping it private until that moment.
- Trigger: On a schedule (Scheduled · daily)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - n8n: Workflow orchestration and automation logic
  - YouTube: Video metadata retrieval, status updates, and scheduling
  - Apify: Extracting video transcripts for analysis
  - OpenAI: Generating SEO-optimized descriptions and tags from transcripts

## Known pitfalls, handle each one explicitly in your implementation
1. Transcripts may contain filler words that confuse the LLM, so instruct the model to ignore non-substantive speech patterns.
2. Scheduling too many videos at once can trigger spam filters, space out publish times by at least a few hours.

## Reference implementation
https://n8n.io/workflows/3900 (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.
