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 mastepanoski/claude-skills at fbdde8adb5.

    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 performs an automated usability audit of digital interfaces using Nielsen’s ten heuristics. It analyzes user flows and interface elements to identify specific violations that hinder accessibility, efficiency, and user satisfaction.

When to use it

  • Before launching a new website or mobile app to catch critical UX flaws early.
  • During iterative design sprints to validate changes against established usability standards.
  • When preparing documentation for stakeholders who need data-backed feedback on interface quality.
  • To benchmark current product performance against industry best practices without conducting live user testing.

Key capabilities

  • Evaluates interfaces against the full set of Nielsen’s 10 heuristics (e.g., visibility of system status, match between system and real world).
  • Generates structured reports highlighting specific areas where usability principles are violated.
  • Provides actionable insights to guide design improvements and reduce user friction.

Example prompts

  • "Audit our checkout flow for violations of the 'Flexibility and efficiency of use' heuristic."
  • "Identify any issues related to error prevention in our login form based on Nielsen's guidelines."
  • "Run a full usability audit on the mobile version of our dashboard and summarize the top three heuristics that are failing."

Tips & gotchas

This tool provides expert-level heuristic analysis but cannot replace actual user testing with real people. Use it as a first-pass diagnostic to prioritize which areas need human-in-the-loop validation.
