Vance Ingalls 6e01980f41 refactor(cli): rename dev command to preview
The command starts a preview server — "preview" describes what users
are doing more accurately than "dev". Updates the command name, file
name, all CLI references, docs, skills, and template CLAUDE.md.

22 files updated across CLI source, docs, skills, and templates.

**Write HTML. Render video. Built for agents.**
Hyperframes is an open-source video rendering framework that lets you create, preview, and render HTML-based video compositions — with first-class support for AI agents via MCP.
## Why Hyperframes?
- **HTML-native** — AI agents already speak HTML. No React required.
- **Frame Adapter pattern** — bring your own animation runtime (GSAP, Lottie, CSS, Three.js).
- **Deterministic rendering** — same input = identical output. Built for automated pipelines.
- **AI-first design** — not a bolted-on afterthought.
## Quick Start
```bash
npx hyperframes init my-video
cd my-video
```
Then open the project with your AI coding agent (Claude Code, Cursor, etc.) — it has HyperFrames skills installed and knows how to create and edit compositions.
```bash
npx hyperframes preview # preview in browser (live reload)
npx hyperframes render # render to MP4
```
**Requirements:** Node.js >= 22, FFmpeg
## Documentation
Full documentation at **[hyperframes.heygen.com](https://hyperframes.heygen.com)** — start with the [Quickstart](https://hyperframes.heygen.com/quickstart), then explore guides, concepts, API reference, and package docs.
## How It Works
Define your video as HTML with data attributes:
```html
<div id="stage" data-composition-id="my-video" data-start="0" data-width="1920" data-height="1080">
<video
id="clip-1"
data-start="0"
data-duration="5"
data-track="0"
src="intro.mp4"
muted
playsinline
></video>
<img id="overlay" data-start="2" data-duration="3" data-track="1" src="logo.png" />
<audio
id="bg-music"
data-start="0"
data-duration="9"
data-track="2"
data-volume="0.5"
src="music.wav"
></audio>
</div>
```
Preview instantly in the browser. Render to MP4 locally. Let AI agents compose videos using tools they already understand.
## Packages
| Package | Description |
| -------------------------------------------- | ----------------------------------------------------------- |
| [`hyperframes`](packages/cli) | CLI — create, preview, lint, and render compositions |
| [`@hyperframes/core`](packages/core) | Types, parsers, generators, linter, runtime, frame adapters |
| [`@hyperframes/engine`](packages/engine) | Seekable page-to-video capture engine (Puppeteer + FFmpeg) |
| [`@hyperframes/producer`](packages/producer) | Full rendering pipeline (capture + encode + audio mix) |
| [`@hyperframes/studio`](packages/studio) | Browser-based composition editor UI |
## AI Agent Skills
HyperFrames ships skills that teach AI coding agents (Claude Code, Gemini CLI, Codex, Cursor) how to write correct compositions and GSAP animations. **Use these instead of writing from scratch — they encode framework-specific patterns that generic docs don't cover.**
### Install via CLI (recommended)
```bash
# Install all skills (HyperFrames + GSAP) — runs automatically during `hyperframes init`
npx hyperframes skills
# Or install to a specific agent
npx hyperframes skills --claude
npx hyperframes skills --cursor
```
### Or via `npx skills add`
```bash
# HyperFrames skills (hyperframes-compose, hyperframes-captions)
npx skills add heygen-com/hyperframes
# GSAP skills (gsap-core, gsap-timeline, gsap-scrolltrigger, gsap-plugins, gsap-performance, gsap-utils, gsap-react, gsap-frameworks)
npx skills add greensock/gsap-skills
```
### Installed Skills
| Source | Skills | What they teach |
| ---------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- |
| **HyperFrames** | `hyperframes-compose`, `hyperframes-captions` | HTML composition structure, `class="clip"` rules, `data-*` attributes, timeline registration, rendering constraints |
| **[GSAP](https://github.com/greensock/gsap-skills)** | `gsap-core`, `gsap-timeline`, `gsap-performance`, `gsap-plugins`, `gsap-scrolltrigger`, `gsap-utils`, `gsap-react`, `gsap-frameworks` | Core API, timeline sequencing, ScrollTrigger, plugin usage, performance best practices |
In Claude Code, invoke with `/hyperframes-compose`, `/hyperframes-captions`, `/gsap-core`, etc.
