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 wondelai/skills at c172996495.

    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 UX Heuristics skill applies established usability principles to evaluate and improve user interfaces. It identifies common design flaws based on Nielsen’s heuristics, such as visibility of system status, match between system and real world, user control and freedom, consistency and standards, error prevention, recognition rather than recall, flexibility and efficiency of use, aesthetics and minimalist design, help users recognize, recover from errors, and assistance and documentation.

When to use it

  • Evaluating a website or app for usability issues before launch.
  • Conducting heuristic evaluations as part of user testing.
  • Improving the accessibility and intuitiveness of an interface.
  • Providing feedback on UI/UX design during development sprints.

Key capabilities

  • Applies Nielsen’s 10 heuristics for usability evaluation.
  • Identifies potential pain points in user interfaces.
  • Suggests actionable improvements based on heuristic violations.
  • Provides clear, structured feedback for developers and designers.

Example prompts

  • "Evaluate the homepage of our new app using UX heuristics."
  • "Check if this login screen follows usability best practices."
  • "Identify any design flaws in this mobile interface according to Nielsen’s principles."

Tips & gotchas

  • Ensure that the UI elements you evaluate are fully developed or at least wireframed for accurate analysis.
  • This skill works best when combined with user testing data for a more comprehensive UX review.
