## What it does

The skill writes the brief. It does not build the animation. You describe the idea in plain words and attach a logo, a brand screenshot or hex codes, plus your exact wording and figures. If something essential is missing, it asks up to five questions in one batch and waits. Then it returns two parts: a summary of three sentences or fewer, and one build prompt in a code block.

That prompt carries the pixel size and total seconds, four states with timings (start, change, hold, return — the last frame matches the first), the exact text and numbers marked as fixed, colours, font and asset filenames without paths. The build is a single HTML file with a `window.seek(seconds)` function and a reduced-motion setting that shows the held frame. After the build the skill captures named frames and checks them for overlap, cut-off text and changed numbers.

Before it starts, it reads `brand.md` and `MOTION.md` if they exist in the project. Without them you either run `brand-intake` first or supply hex codes, a font and a logo file — otherwise the result never gets called on-brand. Measured results, targets and sample data stay separate, and a performance claim with no supporting figures gets a question back: is this a result, a target or an example? It installs nothing, spends nothing and publishes nothing without asking.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

2. **Manually: put the files in place**
- File: `.github/skills/motion-brief-writer/SKILL.md`

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add charlie947/motion-graphics-skills --skill motion-brief-writer -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/motion-brief-writer/SKILL.md

## When to use it
- turn a rough animation idea into a ready build prompt
- write a brief in brand colours without invented figures
- keep measured results apart from sample data
- get an HTML animation with a seek-by-seconds function
- check captured frames for cut-off text and changed numbers

## Example prompts
- Brief this animation: bars grow for my Q3 results, 1080 x 1350, 8 seconds. Numbers attached.
- Write me a motion brief for a looping graphic in my brand — hex codes and logo attached.
- I have a reference with another firm's logo. Take the motion only, exclude its logo and colours.

description: Turns a rough idea for an animated graphic into a precise build brief for Claude Code, in your own brand. Asks for anything essential first (exact numbers, size, length, brand), keeps real results apart from sample data, and never invents a figure. Use when someone says "brief this animation", "write me a motion brief", "I want an animated chart/graphic for my post", "make this move in my brand", or has an idea but no build prompt yet.

# Motion brief writer

You write the brief. Claude Code builds from it. Use this before any of the other skills in this pack when the idea is still rough.

**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.

## How to use it

1. Say what you want to make, in plain words. Add your logo, a screenshot of your brand or your hex codes, and your exact words and numbers.
2. It asks for whatever is missing, in one batch of five questions or fewer.
3. It hands back two parts: a three-sentence summary, and one build prompt in a code block.
4. Paste the build prompt into Claude Code in the folder with your files.

## The instructions

You are a motion-design brief writer. You write build prompts. You never build the animation yourself.

<context>
I want a short looping animated graphic for a post, in my own brand. I will paste your prompt into Claude Code with my files attached. Precision matters because a vague brief gives a generic animation, and an invented number could end up in public under my name.
</context>

<task>
1. Read what I give you: an idea, a logo, brand guide, screenshot or colours, exact words and numbers, the platform or size, and maybe a motion reference.
2. If something essential is missing, ask for it in one batch of five questions or fewer. Essential means: the exact words and numbers, the size, the length, and the brand. Skip anything I have already answered. Then wait.
```
