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.

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 | $0.00044 | $0.01270 |
| Opus 5.5 | $0.00018 | $0.00508 |
| Sonnet 5.5 | $0.00009 | $0.00254 |
| Haiku 4.5 | $0.00004 | $0.00127 |
Grade A, and why
code-slice-hero scanned grade A with 0 findings 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 27d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Slice Hero
A full square-tile surface carries one seamless headline. An imaginary cursor crosses the surface; nearby tiles respond to its Gaussian depth field with lift and tilt, and only the cells intersecting either headline silhouette turn over to reveal the rear headline. The whole grid is one instanced WebGL 2 draw with a shared front/rear texture pair, plus a batched projected-shadow pass. Copy, text size and square cell size are independent, so tiles never stretch. Sweep direction, easing strength, cursor radius, falloff, depth, bounce and shadow are all variables.
Composition id: code-slice-hero. Duration 8 s at 30 fps, 1920×1080.

Install
Install with npx hyperframes add code-slice-hero; by default the files above land under compositions/code-slice-hero/. Then mount the block from the host index.html:
<div
data-composition-id="code-slice-hero"
data-composition-src="compositions/code-slice-hero/code-slice-hero.html"
data-start="0"
data-duration="8"
data-track-index="1"
data-width="1920"
data-height="1080"
></div>
Render with custom values by targeting the composition file directly:
npx --yes [email protected] render 'compositions/code-slice-hero/code-slice-hero.html' --variables '{"headline":"MAKE IT","reverseHeadline":"MATTER."}'
Variables
Read at runtime via window.__hyperframes.getVariables(); declared on the composition root as data-composition-variables (single-quoted attribute, plain JSON).

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

code-slice-hero is a skill published in the GitHub repository heygen-com/hyperframes (65,314 stars, last pushed today), licensed Apache-2.0. It adds 44 tokens to every session and 1,270 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-20.

gsap
A JavaScript animation framework with shared systems for timelines, easing, and timed value changes. It can animate CSS, SVG, Canvas, WebGL, framework state, and other JavaScript objects, with extensions for tasks such as scroll triggers, drag interactions, motion paths, and text animation.
validate-motion
Browse MotionSpec motion primitives and draft or validate a MotionSpec JSON specification for web animation. Use for catalog questions, choosing an available primitive, or checking an existing spec. This workflow validates specifications; it does not compile, deploy or execute animation.
audit-motion
Check a public website's CSS animation and transitions with MotionSpec. Use when the user asks for a motion-accessibility check, reduced-motion support, or pause controls on a specific public URL. Reports static CSS findings and coverage; does not certify accessibility or test flashing.
motion
Author verified, reduced-motion-safe web animation with MotionSpec. Use when adding scroll, entrance, hover, or loop animation to a website or web app — instead of hand-writing GSAP or CSS keyframes, write a MotionSpec JSON spec, validate it, and compile deterministic code.
animation-system-architect
Design performant animation systems with Framer Motion, GSAP, View Transitions API, and spring physics. Activate on: page transitions, micro-interactions, scroll animations, layout animations, spring physics. NOT for: CSS-only hover effects (use css-in-js-architect), video/canvas rendering (use creative-coding-expert).
animejs
A JavaScript library for creating animations with a consistent system for changing CSS properties, SVG, web-page elements, and JavaScript values over time. Optional adapters can handle Three.js and WebGL scenes.
