animejs

animejs is a skill for Claude Code, Codex from delexw/claude-code-misc. It costs 143 tokens per session (3,731 once invoked), scanned A, original, MIT.

A guide for writing animations with anime.js version 4, a JavaScript library for moving and changing elements on web pages. It covers the version’s imports, animation methods, timelines, easing, scrolling, and dragging.

In plain words
What is it for?
Use it when adding animations to HTML, CSS, SVG, or JavaScript interfaces, including scroll effects, drag interactions, and timed sequences.
Why use it?
It helps avoid using older anime.js version 3 syntax with version 4, where the programming interface changed.

Token cost

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.

Security

Grade A, and why

animejs 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 6d 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.

Anime.js v4 Animation Skill

Anime.js v4 is a modular JavaScript animation engine (10KB full / 3KB WAAPI-only). This skill ensures you write correct v4 syntax — the API changed significantly from v3.

Installation

npm install animejs

CDN (ESM):

<script type="module">
  import { animate } from 'https://cdn.jsdelivr.net/npm/animejs/+esm';
</script>

Core Concept: Named Imports

v4 uses named exports, not a default anime object. Import only what you need:

import { animate, stagger, createTimeline, utils } from 'animejs';

Subpath imports for smaller bundles:

import { animate } from 'animejs/animation';
import { createTimeline } from 'animejs/timeline';
import { createDraggable } from 'animejs/draggable';
import { onScroll } from 'animejs/events';
import { stagger, utils } from 'animejs/utils';
import { waapi } from 'animejs/waapi';

Quick Reference: animate()

animate(targets, parameters);

Targets: CSS selectors, DOM elements, NodeLists, JS objects, or arrays of these.

Parameters combine animatable properties + playback settings + callbacks:

animate('.box', {
  translateX: 250,           // CSS transform
  opacity: [0, 1],           // [from, to]
  scale: { from: 0.5, to: 1 },
  backgroundColor: '#FF0000', // color animation
  duration: 800,
  delay: stagger(100),       // stagger per element
  ease: 'outExpo',           // easing function
  loop: 2,                   // repeat 2 times (3 total plays)
  alternate: true,           // ping-pong
  onComplete: () => console.log('done'),
});

Animatable Properties

Category Examples
CSS opacity, width, height, backgroundColor, borderRadius
Transforms translateX, translateY, rotate, scale, skewX
CSS Variables '--my-var': 100
SVG Attributes cx, r, points, d (via morphTo)
HTML Attributes value, data-count
JS Object Props Any numeric property on a plain object

2 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.

Changes

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.
