## What it does

The skill starts by asking for a central question, sourced facts, a palette and a frame size. When facts are missing, the agent is instructed to research them and present sources before making the video. Existing `brand.md` and `MOTION.md` files guide the visual identity; otherwise, the skill asks for brand colours, a font and a logo, or suggests running `brand-intake`.

The script is arranged as 8–14 shots, and the agent waits for approval before building. It then creates a single HTML file with animated cards, paper textures and other graphic treatments. Export can use HyperFrames or another tool that reads `window.seek` and saves frames as MP4. Narration and a coded score are part of the production brief. Each on-screen fact needs a source, so gather those links before asking the agent to build.

## Requirements
- Works with: LinkedIn

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add charlie947/motion-graphics-skills --skill vox-explainer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/vox-explainer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/vox-explainer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add charlie947/motion-graphics-skills --skill vox-explainer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/vox-explainer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add charlie947/motion-graphics-skills --skill vox-explainer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/vox-explainer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install charlie947/motion-graphics-skills vox-explainer
```

2. **Manually: put the files in place**
- File: `.github/skills/vox-explainer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add charlie947/motion-graphics-skills --skill vox-explainer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/charlie947/motion-graphics-skills --path skills/vox-explainer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/vox-explainer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add charlie947/motion-graphics-skills --skill vox-explainer -a opencode
```

### 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/charlie947/motion-graphics-skills/tree/HEAD/skills/vox-explainer/SKILL.md

## When to use it
- turn sourced research into a documentary explainer
- structure a script as short, distinct shots
- build animated graphics in one HTML file
- prepare the video for MP4 export

## Example prompts
- Make a short video explaining why brand logos have started to look alike, and show me the sourced script first.
- Create an explainer for a LinkedIn feed in 1080 x 1350.
- Build this approved shot list as `index.html` and prepare it for MP4 export.

description: Make a short Vox-style documentary explainer (30-60 seconds) entirely in code with Claude Code. Torn paper, halftone texture, bold condensed type, motion on twos. Use when someone says "make a Vox-style video", "explainer video about...", "why does X happen", or wants a documentary-style motion graphic for LinkedIn, Instagram or YouTube without After Effects or a video generator.

# Vox-style explainer, built in code

You make a 30-60 second documentary explainer as one HTML file, then export it to MP4. Every frame is code. No video generator, no stock footage.

**Before you start:** read `brand.md` and `MOTION.md` if they exist. If not, run `brand-intake` first, or ask for hex codes, a font and a logo file. Never call a result on-brand without them.

## Step 1: Ask for four things, then wait

1. **The question.** One "why" question a stranger half understands. Example: "Why does every brand logo look the same now?"
2. **The facts.** Names, dates and numbers that answer it, each with a source link. If the user has none, research them and show the list with sources before building.
3. **The colours.** Three hex codes plus one accent. Default (the palette from my logo film): red #B8312A, cream #F1E6D0, paper #FBF7EE, navy #14213D, yellow accent #F2C230. Label defaults as defaults.
4. **The size.** 1920 x 1080 (YouTube), 1080 x 1350 (LinkedIn feed) or 1080 x 1920 (Story or Reel).

Do not start building until every fact on screen has a source.

## Review rules (from the rounds that got rejected)

- **Sound is not optional.** A silent explainer feels unfinished. Write a score in code: a low bed, a hit on each new shot, a lift on the last line.
- **Cards and images, not lines.** A single bar or line moving across the screen reads as static. Every shot uses cards, real images or objects that move in depth.
- **Logos fill their card** and come from the real files. A logo floating small in a big box looks wrong.
- **Keep grids symmetrical.** Equal card sizes, equal gaps. A lopsided layout reads as a mistake.
- **The voice sits on top.** If you can't hear the narration over the effects, drop the score until you can. A voice track (your own, or a text-to-speech one) carries a "why" film.
- **The opening line has to promise what's coming.** A small title that undersells the film loses people before the good bit. Say the question big, then show the first surprise within 5 seconds.
- **Every spoken fact gets a source** in a facts file before it goes in the script. Say "looks like", never "is", when the research only shows a similarity.
- **Stunning or it's not done.** If the first 3 seconds would not stop your own thumb, rebuild them before building the rest.

## Step 2: Write the script, one line per shot
```
