HyperFrames is an open-source framework that turns HTML, CSS, media, and timed animations into deterministic MP4 videos. It is used locally, by coding agents, and in hosted authoring workflows to create rendered videos from web-based designs. Its catalogue add-ons provide skills, agents, instructions, hooks, settings, and a plugin for agent-driven video production.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 9 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00188 | $0.02165 |
| Opus 5.5 | $0.00075 | $0.00866 |
| Sonnet 5.5 | $0.00038 | $0.00433 |
| Haiku 4.5 | $0.00019 | $0.00216 |
Grade A, and why
hyperframes-registry scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts
The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plugin installs: Before setup or freshness commands, follow plugin execution rules when this skill is inside a HyperFrames plugin. Standalone installs keep the update instructions below.
HyperFrames Registry
The registry provides reusable blocks and components installable via hyperframes add <name>.
- Blocks — standalone sub-compositions (own dimensions, duration, timeline). Included via
data-composition-srcin a host composition. - Components — effect snippets (no own dimensions). Pasted directly into a host composition's HTML.
Quick reference
hyperframes add data-chart # install a block
hyperframes add grain-overlay # install a component
hyperframes add captions # install every block tagged captions
hyperframes add shimmer-sweep --dir . # target a specific project
hyperframes add data-chart --json # machine-readable output
hyperframes add data-chart --no-clipboard # skip clipboard (CI/headless)
After install, the CLI prints which files were written and a snippet to paste into your host composition. The snippet is a starting point — you'll need to add data-composition-id (must match the block's internal composition ID), data-start, and data-track-index attributes when wiring blocks.
The positional value is resolved as an exact item name first. If no item matches and the value is a tag, the command installs every block with that tag. Registry dependencies are installed before the requested item. hyperframes add works only for blocks and components; for examples, use hyperframes init <dir> --example <name> instead.
Install locations
Blocks install to compositions/<name>.html by default. Components install to compositions/components/<name>.html by default.
These paths are configurable in hyperframes.json:
{
"registry": "https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry",
"paths": {
"blocks": "compositions",
"components": "compositions/components",
"assets": "assets"
}
}
What ships with it

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hyperframes-registry is a skill published in the GitHub repository heygen-com/hyperframes (65,314 stars, last pushed today), licensed Apache-2.0. It adds 188 tokens to every session and 2,165 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

motiscope-recreate
Recreate an analyzed animation as working web code — GSAP (JavaScript), CSS/Web Animations, Framer Motion (React), or Lottie/SVG. Use after motiscope-analyze, or when the user asks to "build/recreate this animation in ". Reads the motiscope animation spec and emits a runnable component.
