## What it does

The skill reads the scene in your footage and picks an event that erupts into that same space: a vehicle smashes through a wall, water surges down a corridor, an object from the frame grows to building size. Then `generate_viral_hook` renders the hook and the stitched final in one call and returns both. A title of up to seven words can be burned into the lower third.

Inside is a menu of four hook super-categories: destructive intrusion, physics anomaly, a supersized element from the clip, and a projectile pulled from the clip. The skill advises rotating the category between runs on the same clip, because otherwise regenerations collapse to vehicle, explosion or creature. Typography defaults to bold distressed display type with a thick black outline; thin or un-outlined styles may wobble over the four seconds.

Pika MCP is required: asset upload, media analysis, hook generation and task status. A local file goes through `upload_asset` first and comes back as a `public_url`. If you pass no video, the skill prints a menu and waits instead of guessing an input.

## Install

### Claude Code (native platform)

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Pika-Labs/Pika-Plugins/tree/HEAD/skills/viral-hook/SKILL.md

## When to use it
- add a scroll-stopping intro to a clip without editing
- pick a hook event that fits the actual scene
- burn a title into the lower third
- stitch the hook and the main clip into one file
- vary hooks across repeated generations

## Example prompts
- add a viral hook to /Users/me/Desktop/clip.mp4
- hook + title on my clip: clip.mp4 — "YOUR PROMPTS WON'T SAVE YOU"
- put a scroll-stopper intro on this video, pick the hook yourself

# Viral Hook

Prepends an extreme, no-dialogue ~4s hook to a user's video — an attention-grabbing event
that erupts into the user's own scene, with an optional designed title burned into the
lower third — then hard-cuts into the untouched clip.

`generate_viral_hook` does the whole render in one call and returns BOTH
the hook and the stitched final. This skill's job is the creative judgment the tool can't
make: read the scene, pick a hook action from the menu, and write a title.

## Hook rules (govern what you WRITE as `hook_action`)

1. **Certain to grab attention, fast.** Extreme and unmissable inside ~2s — over plausibility
   or relevance to the video's topic.
2. **Erupts into the user's OWN scene.** Same person, location, lighting — the tool anchors
   on the best visual anchor frame: 0s when usable, otherwise the first detectable face frame.
   Describe the event entering THAT space, never a different setting.
3. **Use the scene's real geometry.** Enter through a doorway with depth, a wall behind the
   subject, headroom above.
4. **No dialogue.** Voice-free (only ambient / impact SFX) — don't write spoken lines into
   `hook_action`.

## Hook super-category menu

Four super-categories. **Rotate** super-category per run on the same clip/session — without
rotation, regenerates collapse to vehicle / explosion / creature. Archetypes are starting
points, not a closed list; invent freely within the category.

### A. Destructive intrusion — external force violently enters and damages the scene

| Archetype | What happens | Scene affordance |
|---|---|---|
| Incoming vehicle | car / truck / bus smashes through a wall or doorway and barrels at camera | background depth or a back wall |
| Flash flood / wave | a wall bursts and water surges down toward camera | corridor / back wall |
| Structural collapse | ceiling / wall / shelf caves in, debris rains down | headroom / walls |
| Explosion / blast | fireball erupts behind them, shockwave + debris rush forward | a background surface |
```
