Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned dylantarre/animation-principles at 83597134ba.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill enables AI agents to generate clean, responsive HTML, CSS, and JavaScript code focused on implementing performant and maintainable animations. It leverages Disney's 12 principles of animation to guide the coding process, ensuring visually appealing and engaging user experiences. The skill provides guidance for both simple state changes using CSS transitions and more complex sequences utilizing JavaScript animation libraries like GSAP or Framer Motion.

When to use it

  • You need to implement a button that compresses on press and stretches during movement.
  • You want to create a card that lifts before expanding, with a preparation state beforehand.
  • You're building a modal window and need to dim the background to focus attention on the content.
  • You require complex animation sequences beyond what CSS transitions can easily provide.

Key capabilities

  • Implementation of Disney’s 12 principles of animation through code (Squash & Stretch, Anticipation, Staging, etc.).
  • Guidance on using transform: scale() for impact and elastic feedback.
  • Recommendations for utilizing transition-delay to sequence movements.
  • Advice on choosing between CSS @keyframes and JavaScript libraries (GSAP, Framer Motion) based on animation complexity.
  • Best practices for performance optimization, including the use of will-change and avoiding animating properties like width, height, or margin.

Example prompts

  • "Create a button that compresses when pressed using CSS scale transformations."
  • "Generate code to make a card lift before expanding, with a brief anticipation phase."
  • "Implement a modal window animation where the background dims and focuses on the content."

Tips & gotchas

  • Prioritize CSS transitions for simple state changes.
  • Always consider accessibility by using the prefers-reduced-motion media query.
  • Batch DOM reads/writes to prevent layout thrashing and optimize performance.
