How to use the Anime.js Animation Helper agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The animejs-animation skill is a set of instructions that teaches an AI agent how to write web animations using Anime.js, a JavaScript animation library. It is for front-end developers and designers who want choreographed motion such as timelines, staggered reveals and animated SVG shapes. By the end of this guide you will know what the skill changes, how to install it, how to ask for work that triggers it, and what to check before shipping the code.
Anime.js Animation Helpersickn33/agentic-awesome-skills · MIT Download the skill Quick start
- 1Download the ZIP. Download the skill ZIP from this page and extract it. You should see SKILL.md inside the animejs-animation folder.
- 2Place the skill folder. Move the animejs-animation folder to ~/.claude/skills/ for personal use, or to .claude/skills/ inside your project.
- 3Or upload it in Claude. In the Claude apps, open Settings, go to Capabilities, then Skills, and upload the skill.
- 4Install Anime.js. Add the animejs package to your project and confirm its major version (v3 or v4).
- 5Make a natural request. Describe the motion, the target selectors and the Anime.js version in plain language.
- 6Review and test. Run the generated code in a browser, check reduced-motion behaviour and confirm selectors exist in the rendered DOM.
What the animejs-animation skill makes the agent do
When the skill is installed, the agent knows how to build interactive web motion with Anime.js. The skill's instructions cover four main areas: sequencing several animations on a timeline, staggering elements so they appear one after another, animating SVG paths such as morphing shapes or drawn lines, and choosing spring, elastic or custom cubic-bezier easing instead of basic linear or ease-in-out curves.
The skill is a single file named SKILL.md. It contains guidance and a code example, not a program that runs on your machine.
- Timelines with relative or absolute offsets so animations overlap smoothly
- anime.stagger() for rhythm across grids, text or data visualisations
- SVG path animation for morphing and drawing effects
- Spring and elastic easing for a more natural feel
Install the skill (ZIP download or Claude Settings)
Download the ZIP for this skill from this page. The skill folder is plugins/agentic-awesome-skills-claude/skills/animejs-animation and it contains SKILL.md. Unzip it so the animejs-animation folder sits in one of these locations:
You can also install it through the Claude apps: open Settings, go to Capabilities, then Skills, and upload the skill there.
- Personal install: ~/.claude/skills/animejs-animation/
- Project install: .claude/skills/animejs-animation/ inside your project folder
Set up Anime.js in your project
The skill expects the Anime.js library to already be in your project, and a bundler or script setup that can import the animejs package. The examples in the skill use Anime.js v3 syntax. The skill also supports v4 in principle, but its code examples do not cover v4, and the agent should not mix the two major versions.
Before writing code, the skill tells the agent to check which major version of Anime.js is installed. Make sure the version in your project matches what you expect.
- Anime.js v3 or v4 installed in the project (examples use v3)
- A bundler or script setup able to import the animejs package
- Selectors in your HTML that exist when the animation runs
How to trigger the skill with a natural request
You do not need a special command. Describe the motion you want in plain language and mention the kind of work involved. The skill is meant for multi-stage landing page sequences, staggered reveals for grids or text, SVG path animation, and interactive kinetic elements that respond to user input.
Name the element selectors and the effect you want. The more specific the request, the less the agent has to guess.
- "Create a staggered reveal for the .feature-card elements on our landing page using Anime.js."
- "Animate the SVG path in #logo so it draws itself on page load with Anime.js v3."
- "Build a three-step timeline: headline slides up, then the hero image scales in with a 800ms overlap."
Example: a staggered hero timeline
The skill includes this example in its instructions. It uses anime.timeline() with a spring easing, staggers the text, and starts the image 800 ms before the text finishes using a relative offset. Treat it as a pattern to adapt, and test it against your own selectors.
const tl = anime.timeline({
easing: "spring(1, 80, 10, 0)",
duration: 1000,
});
tl.add({
targets: ".hero-text",
translateY: [50, 0],
opacity: [0, 1],
delay: anime.stagger(100),
}).add(
{ targets: ".hero-image", scale: [0.9, 1], opacity: [0, 1] },
"-=800",
);Safety notes: scripts and network
The skill declares that it runs no scripts and uses no network access. It is a set of written instructions, so installing it does not run code on your computer. The code it produces is still your code: review it, test it in a browser, and check it against your project's setup before deploying.
The skill also reminds the agent to respect prefers-reduced-motion by providing a static final state, avoid hijacking page scrolling, keep keyboard and focus interactions usable, and dispose of animations when a component unmounts. Ask the agent to follow these points explicitly if your audience needs minimal motion.
- Runs scripts: no
- Uses network: no
- Licence: MIT
Tips for better results
Use motion where it serves the task. The skill says simple transitions and static states are valid choices, so you can ask the agent to skip animation for small interface details. Monitor main-thread work and measure real frames when you use will-change, because the skill notes it is a hint rather than a guarantee of GPU acceleration.
- Always state your Anime.js major version in the request
- Ask for a reduced-motion fallback that shows the final state
- Use plain CSS for simple hover or fade effects
- Test performance on a real device, not just a desktop browser
What people use it for
- Staggered reveal of a product feature grid as the user scrolls into view
- Multi-stage hero animation where headline, image and call-to-action overlap on a timeline
- SVG logo that draws its own outline on page load
- Animated data visualisation where bars or points appear in sequence
Frequently asked questions
How do I install the animejs-animation skill?
Download the ZIP from this page and unzip it so the animejs-animation folder sits in ~/.claude/skills/ for personal use or .claude/skills/ inside a project. You can also upload it in the Claude apps under Settings, then Capabilities, then Skills.
What does the animejs-animation skill require?
It requires the Anime.js library installed in your project, either v3 or v4, and a bundler or script setup that can import the animejs package. The examples use v3 syntax, so v3 is the simplest starting point.
Is the animejs-animation skill free?
The skill is published under the MIT licence. The source page does not list pricing for it, and Anime.js itself is a separate library that you install in your project.
Does the skill run scripts or use the internet?
The skill declares that it runs no scripts and uses no network access. It consists of a SKILL.md instruction file, so review the code the agent writes as you would any other code.
Can I use this skill with Anime.js v4?
The skill's examples use v3, and its guidance warns against mixing major versions. For v4, check the official timeline documentation for the installed version and ask the agent to follow v4 syntax throughout.
Should I use this skill instead of plain CSS animations?
Use plain CSS transitions for simple hover or fade effects, since the skill leans toward heavier, choreographed motion. Choose this skill when you need timelines, staggering, SVG path work or spring easing.

Our verdict
This skill suits front-end developers and designers who already use Anime.js or want choreographed reveals, timelines and animated SVGs on landing pages or product sites. Skip it for simple hover or fade effects that CSS handles well, for projects that have not chosen Anime.js, and for sites where motion must stay minimal unless you explicitly instruct the agent to follow the reduced-motion guidance.
