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 notedit/happy-skills at 9a2d593b62.

    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

The spring-animation skill allows AI agents to create smooth, physics-based animations. It enables transitions and movements that mimic real-world spring behavior, providing a more engaging user experience than simple linear changes. This includes animating properties like position, scale, or opacity with realistic acceleration and deceleration.

When to use it

  • UI Transitions: Animate the appearance of elements when opening menus or displaying notifications for a polished feel.
  • Interactive Elements: Create playful animations for buttons or other interactive components that respond to user input.
  • Loading Indicators: Replace standard loading spinners with more dynamic and visually appealing spring-based animations.
  • Game Development: Implement realistic movement and interactions in simple games or simulations.

Key capabilities

  • Spring-based animation of properties
  • Realistic acceleration and deceleration effects
  • Customizable stiffness, damping, and mass parameters
  • Transitions between states

Example prompts

  • "Animate the 'Submit' button to spring into view when the form is ready."
  • "Create a bouncing loading indicator using a spring animation."
  • "Make the menu slide in with a spring transition effect."

Tips & gotchas

The skill requires understanding of basic physics concepts like stiffness, damping, and mass. Experimenting with these parameters will be necessary to achieve the desired visual effect.
