YouTube Copy

Write the four pieces of YouTube metadata that drive clicks and rank: title, description, tags, chapters. Ground everything in the provided source (transcript / topic) — never invent claims the source doesn't support. For chapters you need a timestamped source (SRT or words.json); without timestamps, ask for them or skip chapters.

Output format

Write youtube.md (or print the same structure) exactly like this:

# YouTube

**Title**

<title>

**Description**

<description>

**Tags**
