## What
CI workflow that auto-renders preview thumbnails for new/changed registry blocks and components on pull requests.
**New files:**
- `scripts/generate-catalog-previews.ts` — catalog preview renderer supporting all three registry item types
- `.github/workflows/catalog-previews.yml` — GitHub Actions workflow triggered on PRs touching `registry/blocks/` or `registry/components/`
## Why
Phase B of the catalog plan (PR 8). After this lands, future block/component PRs don't need to manually generate preview images — CI handles it automatically.
## How
The preview script discovers items from the registry directory structure:
- **Examples**: renders `index.html` (same as the existing `generate-template-previews.ts`)
- **Blocks**: renders the block's standalone HTML file directly (e.g., `data-chart.html`)
- **Components**: renders the component's `demo.html` (the demo.html convention from PR 7)
The CI workflow:
1. Detects which blocks/components changed in the PR via `git diff`
2. Renders thumbnails for only the changed items (not the full catalog)
3. Uploads preview PNGs as artifacts
Output goes to `docs/images/catalog/<type>/<name>.{png,mp4}` (separate from the existing `docs/images/templates/` directory).
Supports CLI flags: `--only <name>`, `--type <example|block|component>`, `--skip-video`.
## Test plan
- [x] Script compiles and passes typecheck (`lefthook pre-commit` ran lint + typecheck + format)
- [x] Workflow YAML is valid (standard GitHub Actions syntax, follows existing ci.yml patterns)
- [ ] Full end-to-end test requires Chrome + FFmpeg (runs in CI, not testable locally without producer deps)
Hyperframes
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
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.
npx hyperframes preview # preview in browser (live reload)
npx hyperframes render # render to MP4
Requirements: Node.js >= 22, FFmpeg
Documentation

How It Works
Define your video as HTML with data attributes:
<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.

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)
# 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
# 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
