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 media (images, videos, audio) against the WCAG (Web Content Accessibility Guidelines) perceivability principles. It identifies potential accessibility issues related to things like color contrast, alternative text for images, captions for video, and audio descriptions. The goal is to help ensure that multimedia content is usable by people with disabilities.

When to use it

  • Website Audits: Evaluate a website's media content for WCAG compliance before launch or during redesigns.
  • Content Creation Review: Check newly created videos, images, and audio files for accessibility issues prior to publication.
  • Accessibility Remediation: Identify specific areas of existing media that need adjustments to meet WCAG standards.
  • Training & Education: Use it as a learning tool to understand how to create accessible media content.

Key capabilities

  • WCAG perceivability assessment
  • Image alternative text evaluation
  • Video caption and audio description analysis
  • Color contrast checks for images

Example prompts

  • "Audit this image [image URL] against WCAG guidelines."
  • "Analyze the accessibility of this video [video URL], focusing on captions and audio descriptions."
  • "Check the color contrast of this image [image URL]."

Tips & gotchas

This skill requires a valid URL for the media to be audited. While it identifies potential issues, it's important to understand that WCAG compliance often involves subjective judgment and may require human review.
