Hyperframes

Write HTML. Render video. Built for agents.

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:

claude plugin marketplace add heygen-com/hyperframes
claude plugin install hyperframes@hyperframes

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:

npx skills add heygen-com/hyperframes

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 <name> 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 workflows install on demand — the router runs npx hyperframes skills update <workflow> before entering one. Nothing re-pulls the full set behind your back.
