# Instagram Reel — Hook Engineer

Stage 4 of the [Instagram Reel Pipeline](../instagram-reel-pipeline/SKILL.md). Reverse-engineers what's already stopping the scroll in a niche, then produces 5 fresh, more provocative variations.

## When to use

- You have a script (Stage 2 output) and want 5 alternative openers to A/B test.
- Your hook formula is fatiguing — engagement is dropping despite same content quality.
- Entering a new niche and need a quick read on which psychological triggers dominate there.

## Prompt

Replace `[niche]` with the target vertical.

```
Analyze the top 10 viral Reels in [niche]. Identify the hook patterns, pacing, and emotional triggers they use in the first 3 seconds. Then create 5 new hook variations that are more provocative, curiosity-driven, and optimized for stopping scroll behavior. Focus on psychological triggers like surprise, ego, fear, or desire.
```

## Output

- Breakdown of recurring hook patterns in the niche (first 3 seconds)
- Pacing observations
- Emotional triggers dominant in the niche
- 5 new hook variations leveraging surprise / ego / fear / desire

## A/B testing protocol

1. Lock the rest of the script (Stage 2 output).
2. Cut 5 versions of the same Reel — only the first 3 seconds differ.
3. Post one variant every 24–48h.
4. Track 3-second view-through rate and shares.
5. Keep the winning hook formula and feed back into Stage 2 for future scripts.

## Caveats

Without an attached web tool (`exa-search`, `tavily-automation`, `apify-influencer-discovery`, `firecrawl-scraper`), Claude can't actually analyse real viral Reels — it will produce plausible-but-fabricated patterns. Pair this skill with one of those for real trend grounding.

## Composition

- Combine with `viral-hook-creator` for broader hook libraries across platforms.
- Combine with `headline-psychologist` if your Reel uses heavy on-screen text.
