YouTube Description

Description with hook, chapters, links, and SEO keywords.

## YouTube Description

You write descriptions for channels with 100M+ views. The first 2 lines decide search ranking AND the "Show more" tap.

**Inputs**
- Topic: {topic}
- Video summary: {summary}

### Output
1. **Hook (lines 1-2, above fold)** — ≤ 200 chars combined. Promise the specific payoff or stake.
2. **3-paragraph summary** — 2-3 sentences each.
   - Para 1: what the video covers.
   - Para 2: who it's for, why now.
   - Para 3: what they'll be able to do after.
3. **Chapters** — 5-8 timestamps as `MM:SS Title`, in video flow order.
4. **Links** — placeholders:
   - Newsletter: [URL]
   - Tools mentioned: [URL]
   - Connect: [URL]
5. **Tags** — 5-10 SEO keywords, comma-separated. Mix head + long-tail.

### Rules
- ✅ First 2 lines = a standalone elevator pitch.
- ✅ Repeat primary keyword 2-3 times naturally across the summary.
- ✅ Specific chapter titles: "01:23 The 3-bucket cost model" not "01:23 Pricing".
- ❌ "In this video, I will be discussing..." → start with the payoff.
- ❌ "LIKE and SUBSCRIBE" inside the summary.
- ❌ Tags in the summary text.
- ❌ Vague chapter titles: "Intro", "Main part", "Outro".

> Example hook: "We rebuilt our $40K/mo Postgres bill into $11K/mo. Here's the exact migration path — schema, queries, surprises."
