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 jkense/agent-skills-wcag at 7fc6eec6ad.

    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 assesses web pages for color contrast issues that could impact users with color blindness, aligning with Web Content Accessibility Guidelines (WCAG). It identifies potential accessibility barriers related to perceivable color combinations. The skill helps ensure sufficient contrast ratios between text and background colors to meet WCAG standards.

When to use it

  • Website Audits: Evaluate a website's compliance with WCAG guidelines regarding color contrast.
  • Design Reviews: Check the color schemes of new designs before implementation.
  • Accessibility Remediation: Identify specific areas on a webpage that need color adjustments for better accessibility.
  • Content Creation: Ensure sufficient color contrast when creating new web content, such as infographics or presentations.

Key capabilities

  • Color contrast assessment
  • WCAG compliance checking
  • Identification of potential accessibility barriers related to color blindness

Example prompts

  • "Check the color contrast on [URL] for readability by people with color blindness."
  • "Does this webpage, [URL], meet WCAG guidelines for color contrast?"
  • "Analyze the color scheme of this design mockup and identify any potential issues for users with color blindness."

Tips & gotchas

The skill's effectiveness depends on providing a valid URL to the web page or design being assessed. It is important to note that this skill focuses solely on color contrast; a full accessibility audit requires evaluating other aspects of website usability.
