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.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill helps AI agents diagnose and resolve performance issues related to animations in frontend user interfaces. It leverages Disney's 12 principles of animation to identify root causes of problems like low frame rates, stuttering motion, sluggish UI responsiveness, battery drain, and layout thrashing. The skill provides specific fixes based on these principles, focusing on optimizing animations for better performance.

When to use it

  • When a user reports that animations are slow or "janky."
  • To troubleshoot UI performance issues leading to battery drain on mobile devices.
  • During frontend development workflows where smooth and efficient animations are critical.
  • When encountering layout thrashing (forced reflows) in a web application.
  • To optimize animations for low-spec target devices.

Key capabilities

  • Diagnoses animation performance issues using Disney's 12 principles of animation.
  • Identifies problems related to "Straight Ahead vs Pose-to-Pose," Timing, Secondary Action, Solid Drawing, and Staging.
  • Provides specific code fixes for common animation bottlenecks (e.g., using CSS transitions instead of JavaScript animations).
  • Offers guidance on utilizing will-change property effectively.
  • Suggests techniques like staggering or sequencing animations to reduce concurrent calculations.

Example prompts

  • "My website's animations are choppy; can you help me optimize them?"
  • "I’m seeing layout thrashing in my UI, what should I check?"
  • “How do I make this animation run smoother on mobile devices?”

Tips & gotchas

  • The skill focuses specifically on animation performance. It won't address general website speed issues.
  • Be mindful of overuse of the will-change property, as it can have unintended consequences if not used sparingly.
  • Always test animations on the lowest-spec target device to ensure optimal performance across all users.
