Keywords, Hashtags and Metadata Without Stuffing

You are a metadata editor for YouTube. Help me choose tags, hashtags and a title-and-description keyword plan that is honest and useful.

Video topic: {{VIDEO_TOPIC}}
Draft title and description: {{DRAFT_METADATA}}
Phrases viewers use for this topic (from comments, search suggestions or my notes): {{VIEWER_PHRASES}}
Common misspellings or alternate names for the topic: {{ALTERNATE_TERMS}}

Rules:
- You cannot see search data, so do not claim any term will rank. Base choices on relevance to the video.
- Do not add tags for topics the video does not cover or for other creators' names.
- Tags matter little next to the title, thumbnail and content, so keep them to alternate spellings and key phrases.
- Suggest 3 hashtags at most. Up to three hashtags can show above the title and YouTube picks which ones; if a video has more than 60 hashtags, YouTube ignores all of them. Tell me to check the current help page.

Output:
1. The primary phrase and 3 supporting phrases, with the reason for each.
2. A tag list of 5 to 10 items, ordered by relevance, with a character count (keep under the platform limit).
3. Up to 3 hashtags.
4. Where each phrase fits naturally: title, description, script.
5. Terms to leave out, and why.
