 81884a7495 fix(cli,skills): install workflow skills on demand instead of re-pulling the full set (#2012) 
* fix(cli,skills): install workflow skills on demand instead of re-pulling the full set

Users report every init re-pulls all 21 skills into ~/.agents/skills
whenever anything is stale or missing - heavy, noisy, and it re-expands
deliberate partial installs.

Split the set into two tiers:

- core: the /hyperframes router + hyperframes-* domain skills +
  media-use, which every workflow references structurally. init and
  bare 'skills update' keep these (plus anything already installed)
  fresh, and never expand the install.
- on demand: the end-user workflow skills (and figma). They install at
  trigger time via 'skills update <name...>' - positional names are
  the only way update expands an install: one targeted
  'skills add --skill <name>' covering only stale/missing targets, a
  fast no-op when current, presence-verified after install, exit 1 on
  unknown names, and a presence-only degrade when GitHub is
  unreachable.

The /hyperframes router now runs 'skills update <workflow>' after
routing and before reading the workflow skill, so a routed workflow is
guaranteed present even on a machine that only has the core set. Each
on-demand skill also opens with the same self-maintenance step (run
'npx hyperframes skills update <name>' silently), so a workflow
triggered directly - without the router - still refreshes itself and
restores any missing core skill before relying on it.

When the manifest is unreachable (offline / rate-limited) the engine
degrades honestly instead of claiming success: named runs presence-check
the request plus a pinned fallback core list (unit-pinned to skills/)
and blind-install whatever is absent; a bare strict update fails loudly
so the 'check || update' chain can't pass while everything stays stale;
init reports the skipped freshness check. --json emits structured
errors on failure paths.

skills check still lists every skill, but exits non-zero only for
stale installed skills, an incomplete core set, or removed leftovers -
workflow skills not yet installed are reported as available on demand.
Bare 'hyperframes skills' (and 'skills add --all') remain the explicit
full-set installs.

Verified end-to-end with a sandboxed $HOME: fresh init installs the 9
core skills only; 'skills update slideshow' adds exactly that skill
(no-op on re-run, exit 1 on unknown names); bare update refreshes
without expanding; a live Claude Code run routed PR-to-video, executed
the router's update step, and the workflow skill appeared before use;
and a second live run triggered an installed workflow directly, whose
opening maintenance step restored a deliberately removed core skill.

* docs(skills): clarify update-engine contracts + document lazy-install model

- skills.ts: note the UpdateSkillsResult.unknown strict-mode contract,
  verifyInstalled's non-strict (warn-not-throw) intent, and that a
  partial install stays "refreshed but never expanded" (review nits).
- docs/guides/skills.mdx: add a "Keeping skills current" section covering
  the core-eager / workflow-on-demand model and the skills check|update
  commands, per the repo's catalog-maintenance rule.

</p>
HyperFrames is an open-source framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. Use it locally with the CLI, from AI coding agents with skills, or as the rendering core behind hosted authoring workflows.
## Quick Start
### With an AI coding agent
Install the HyperFrames skills, then describe the video you want:
```bash
npx skills add heygen-com/hyperframes --full-depth --yes
```
> `--full-depth` does a full clone of the repo's current `main`. Without it, `skills add` fetches the skills.sh registry blob, which lags `main` by hours — you'd get an older copy of a skill. (`hyperframes skills update` already installs full-depth.)
Try a prompt like:
> Using `/hyperframes`, create a 10-second product intro with a fade-in title, a background video, and subtle background music.
The skills teach agents the HyperFrames production loop: plan the video, write valid HTML, wire seekable animations, add media, lint, preview, and render. They work with Claude Code, Cursor, Gemini CLI, Codex, and other coding agents that support skills.
## Skills
HyperFrames ships 20 skills agents load on demand. Read `/hyperframes` first — it's the router and capability map; it picks a workflow for any "make me a…" request — video, deck, or composition port — and points to the domain skills below.
Run `npx skills add heygen-com/hyperframes --full-depth` for the interactive picker, `npx skills add heygen-com/hyperframes --all --full-depth` to install all 20 at once (skips the picker), or `npx skills add heygen-com/hyperframes --skill <name> --full-depth` for just one (bare name, no leading `/`). Keep `--full-depth` — it installs the current `main`; without it `skills add` fetches the skills.sh blob, which lags by hours.
Installs stay lean after that: `npx hyperframes init` keeps the **core set** fresh (the router, the `hyperframes-*` domain skills, and `media-use` — plus whatever is already installed; `/figma` stays on demand) and never expands a partial install; the creation workflows install **on demand** — the router runs `npx hyperframes skills update <workflow>` before entering one. Nothing re-pulls the full set behind your back.
### Router
| Skill | Use when |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `/hyperframes` | **Read first** for any request to make / create / edit / animate / render a video, animation, or motion graphic. Capability map for the domain skills and intent router for the creation workflows below. |
### Creation workflows
| Skill | Use when |
| -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `/product-launch-video` | Marketing / launching / promoting a **product** — from its URL, a brief, or a script (even if the site is only named). Up to ~3 min (sweet spot 30-90s). |
| `/website-to-video` | Turning a **general website** into a video — site tour, portfolio / landing-page showcase, social clip from the site's own visuals. |
| `/faceless-explainer` | **Explaining a topic / concept** from arbitrary text — no product, no URL, no website capture; every visual is LLM-invented (typography / abstract / diagram / data-viz). |
| `/pr-to-video` | A **GitHub pull request** (PR URL, `owner/repo#N` ref, or "this PR") → changelog / feature-reveal / fix / refactor explainer, read via the `gh` CLI. |
| `/embedded-captions` | Adding **captions / subtitles** to an existing talking-head video (footage untouched) — verbatim rail, embedded climax behind the subject, or pure-cinematic embed. |
| `/talking-head-recut` | Packaging an existing talking-head / interview / podcast video with **designed graphic overlays** — lower-thirds, data callouts, kinetic titles, pull-quotes, side panels, PiP. |
| `/motion-graphics` | A short, **unnarrated, design-led motion graphic** (~under 10s) — kinetic type, stat / chart hit, logo sting, lower-third, animated tweet / headline. MP4 or transparent overlay. |
| `/music-to-video` | A **music track** (audio file, or video to pull audio from) → a **beat-synced** video — lyric, slideshow, or kinetic promo; music drives pacing. |
| `/slideshow` | A **presentation / pitch deck / interactive deck** — discrete slides, fragment reveals, branching, hotspot navigation, presenter mode. Output is a navigable deck, not a rendered video. |
| `/general-video` | **Anything else** — longer or multi-scene pieces, brand / sizzle reel, title card, static loop, freeform composition. Input- and length-agnostic fallback. |
| `/remotion-to-hyperframes` | **Porting an existing Remotion** (React) composition's source to HyperFrames HTML. One-way migration, not creation. |
### Domain skills (loaded on demand)
Atomic capabilities the creation workflows compose against — pull one when you need that specific layer.
| Skill | Covers |
| ------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `/hyperframes-core` | The composition contract — `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, determinism rules. |
| `/hyperframes-animation` | All animation knowledge — atomic motion rules, scene blueprints, transitions, runtime adapters (GSAP / Lottie / Three.js / Anime.js / CSS / WAAPI / TypeGPU). |
| `/hyperframes-keyframes` | Seek-safe keyframe authoring across runtimes — GSAP timelines, CSS keyframes, Anime.js, WAAPI, FLIP, paths, masks, SVG morph/draw, 3D depth — plus `hyperframes keyframes` diagnostics for rendered motion. |
| `/hyperframes-creative` | Non-animation creative direction — `frame.md` / `design.md`, palettes, typography, narration, beat planning, audio-reactive visuals, composition patterns. |
| `/media-use` | The media OS — resolve any media need (BGM, SFX, image, icon, logo, voice) into a frozen local file + ledger record, generate via TTS/music/image models when the catalog misses, transcribe, caption, remove backgrounds, and reuse assets across projects. One shared audio engine + manifest tracking. |
| `/hyperframes-cli` | CLI dev loop — `init`, `lint`, `validate`, `inspect`, `preview`, `render`, `publish`, `doctor`, plus AWS Lambda cloud rendering (`lambda deploy / render / progress`). |
| `/hyperframes-registry` | Install and wire registry blocks and components into compositions via `hyperframes add`. Authoring a new block or component to contribute upstream. |
| `/figma` | Import Figma assets, tokens, components, and storyboard sections → reconstructed motion (frames read as states, not slides) (REST/CLI) plus Motion animations (MCP) and shaders (MCP source / native export) into a composition. |
For visual design handoff workflows, see the [Claude Design guide](https://hyperframes.heygen.com/guides/claude-design) and [Open Design guide](https://hyperframes.heygen.com/guides/open-design).
### Manually with the CLI
```bash
npx hyperframes init my-video
cd my-video
npx hyperframes preview # preview in browser with live reload
npx hyperframes render # render to MP4
```
**Requirements:** Node.js 22+, FFmpeg
## What You Can Build
Need ideas? Browse the [Showcase](https://hyperframes.heygen.com/showcase) for finished videos you can watch, read, run, and remix.
- Product launch videos and feature announcements
- PR walkthroughs with animated code diffs, narration, and captions
- Data visualizations, chart races, and map animations
- Social videos with kinetic captions, overlays, and music
- Docs-to-video, PDF-to-video, and website-to-video explainers
- Reusable motion graphics for automated content pipelines
## Frame.md
**frame.md — your design system, ready for video.**
Every brand has a `design.md`. None of them were written for a camera. `frame.md` is the missing translation layer: it takes your web-context design spec and inverts it for the frame — the same tokens, the same rules, but rewritten so an AI agent can compose a promo video without guessing at scale or reaching for web chrome.
The output is a `DESIGN.md` superset your whole toolchain can read. Atoms stay sacred. Composition stays free. Numbers come from the script.

## How It Works
Define a video as HTML. Add data attributes for timing and tracks. Use GSAP, CSS, Lottie, Three.js, Anime.js, WAAPI, or your own frame adapter for seekable animation.
```html
<div id="stage" data-composition-id="launch" data-start="0" data-width="1920" data-height="1080">
<video
class="clip"
data-start="0"
data-duration="6"
data-track-index="0"
src="intro.mp4"
muted
playsinline
></video>
<h1 id="title" class="clip" data-start="1" data-duration="4" data-track-index="1">Launch day</h1>
<audio
data-start="0"
data-duration="6"
data-track-index="2"
data-volume="0.5"
src="music.wav"
></audio>
<script src="https://cdn.jsdelivr.net/npm/gsap@3/dist/gsap.min.js"></script>
<script>
const tl = gsap.timeline({ paused: true });
tl.from("#title", { opacity: 0, y: 40, duration: 0.8 }, 1);
window.__timelines = window.__timelines || {};
window.__timelines.launch = tl;
</script>
</div>
```
Preview instantly in the browser. Render locally or in Docker. The renderer seeks each frame in headless Chrome and encodes the result with FFmpeg, so the same input produces the same video.

## Why HyperFrames?
- **HTML-native:** compositions are HTML files with data attributes. No React requirement, no proprietary timeline format.
- **Agent-friendly:** agents already write HTML, and the CLI is non-interactive by default.
- **Deterministic:** same input, same frames, same output. Built for CI, regression tests, and automated rendering.
- **No build step:** an `index.html` composition plays as-is and can be previewed directly in the browser.
- **Adapter-based animation:** bring GSAP, CSS animations, Lottie, Three.js, Anime.js, WAAPI, or a custom runtime.
- **Open source:** Apache 2.0 license, with no per-render fees or commercial-use thresholds.
## HyperFrames vs Remotion
HyperFrames is inspired by [Remotion](https://www.remotion.dev). Both tools render video with headless Chrome and FFmpeg. The main difference is the authoring model: Remotion's bet is React components; HyperFrames' bet is plain HTML that humans and agents can both write easily.
| | **HyperFrames** | **Remotion** |
| ------------------------ | ------------------------------------- | --------------------------------------- |
| Authoring | HTML + CSS + seekable animation | React components |
| Build step | None; `index.html` plays as-is | Bundler required |
| Agent handoff | Plain HTML files | JSX / React project |
| Library-clock animations | Seekable, frame-accurate via adapters | Wall-clock animation patterns need care |
| Distributed rendering | Local and AWS Lambda render paths | Remotion Lambda, mature cloud renderer |
| License | Apache 2.0 | Source-available Remotion License |

## Development Note
The repo uses [Git LFS](https://git-lfs.com) for golden regression-test baselines under `packages/producer/tests/**/output.mp4` (about 240 MB of `.mp4` files). If you're cloning the full repo for development, install Git LFS first:
```bash
# macOS
brew install git-lfs
# Ubuntu / Debian
sudo apt install git-lfs
# Windows
winget install GitHub.GitLFS
# Then, once per machine
git lfs install
```
If you only need source files, you can skip LFS content:
```bash
GIT_LFS_SKIP_SMUDGE=1 git clone https://github.com/heygen-com/hyperframes.git
```
