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
For Claude Code, install the versioned plugin:
 [code] 
Enable auto-update for the **hyperframes** marketplace in `/plugin` → **Marketplaces**,
then use `/hyperframes:hyperframes`. See the plugin guide
for Copilot, VS Code, Cursor, Gemini CLI, updates, and migration.
For standalone skills (including OpenCode), use:
 [code] 
> The picker opens with nothing pre-selected — the **Core Skills** group is all you need: the `/hyperframes` router installs each creation workflow on demand. Agents and non-interactive runs should use `npx hyperframes skills update` instead — it installs exactly the core set, whereas `skills add --all` installs all 21 published skills. The six repo-internal skills under `.claude/skills` / `.agents/skills` are excluded by default. For the full published set use `npx hyperframes skills`.
>
> `skills add` resolves the skills.sh registry blob, which can lag `main` by hours. `npx hyperframes skills update` installs from the current `main`, so reach for it when you need the newest copy of a skill.
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, Codex, Cursor, Gemini CLI, IBM Bob, and other coding agents that support skills.
## Skills
HyperFrames ships 21 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.
For standalone installation, default to the **core set** — the router installs each creation workflow on demand. `npx hyperframes skills update` installs exactly that from anywhere; the interactive picker (`npx skills add heygen-com/hyperframes`) lists it as the "Core Skills" group, nothing pre-selected. The picker is interactive-only — a non-interactive or agent run without `--skill` installs all 21. Use `npx skills add heygen-com/hyperframes --all` to install the complete published set deliberately (skips the picker), or `npx skills add heygen-com/hyperframes --skill ` for just one (bare name, no leading `/`).
Standalone 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 wor
