Lottie for HyperFrames
HyperFrames can seek both lottie-web and dotLottie players through its lottie runtime adapter. Lottie is a strong fit because the animation timeline is already encoded in the asset; HyperFrames only needs a player object it can seek.
Contract
- Load assets from local project files, usually under
assets/. - Set
autoplay: false. - Prefer
loop: falseunless the user explicitly wants a loop. - Register every returned animation or player on
window.__hfLottie. - Keep the Lottie container dimensions stable with CSS.
The adapter seeks lottie-web with goToAndStop(timeMs, false) and dotLottie with frame or percentage APIs depending on player shape.
lottie-web Pattern
<div id="logo-lottie" class="lottie-layer"></div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bodymovin/5.12.2/lottie.min.js"></script>
<script>
const anim = lottie.loadAnimation({
container: document.getElementById("logo-lottie"),
renderer: "svg",
loop: false,
autoplay: false,
path: "assets/logo-reveal.json",
});
window.__hfLottie = window.__hfLottie || [];
window.__hfLottie.push(anim);
</script>
.lottie-layer {
width: 100%;
height: 100%;
}
dotLottie Pattern
<canvas id="product-lottie" class="lottie-canvas"></canvas>
<script src="https://unpkg.com/@lottiefiles/dotlottie-web"></script>
<script>
const player = new DotLottie({
canvas: document.getElementById("product-lottie"),
src: "assets/product-flow.lottie",
autoplay: false,
loop: false,
});
window.__hfLottie = window.__hfLottie || [];
window.__hfLottie.push(player);
</script>
.lottie-canvas {
width: 100%;
height: 100%;
display: block;
}
Multiple Animations
Push each player into the same registry:
window.__hfLottie = window.__hfLottie || [];
window.__hfLottie.push(backgroundAnim);
window.__hfLottie.push(iconAnim);
window.__hfLottie.push(confettiAnim);
HyperFrames seeks them all to the same composition time.
Good Uses
- After Effects exports that are already known to render correctly in lottie-web.
- Logo reveals, icon loops, decorative accents, and product UI motion.
- Translating Remotion Lottie usage into plain HyperFrames HTML.
Avoid
- Relying on remote
pathURLs at render time. - Starting playback with
play(). - Assuming unsupported After Effects effects will survive export. Test the JSON or
.lottiefile in a browser first. - Loading a player asynchronously and registering it after HyperFrames validation has already inspected the page.
Validation
After editing a Lottie composition:
npx hyperframes lint
npx hyperframes validate

FAQ
What does the lottie skill do?
Lottie and dotLottie adapter patterns for HyperFrames. Use when embedding lottie-web JSON animations, .lottie files, @lottiefiles/dotlottie-web players, registering instances on window.hfLottie, or making After Effects exports deterministic in HyperFrames.
How do I install lottie?
Run npx skills add https://github.com/heygen-com/hyperframes --skill lottie in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/lottie/ (personal) or .claude/skills/lottie/ (project).
Which AI agents can use lottie?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is lottie safe to install?
Security partners have reviewed it: Gen Agent Trust Hub passed; Socket passed; Snyk flagged items to review. As with any skill, read the SKILL.md and bundled scripts before installing.

Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).

codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
