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 performs a basic accessibility audit focused on the "Perceivable" section of WCAG (Web Content Accessibility Guidelines). It checks for common issues related to text contrast, font size, and alternative text for images. The tool helps identify potential barriers for users with visual impairments or other disabilities.

When to use it

  • You've created a new webpage or document and want a quick accessibility check.
  • A user reports difficulty reading content on your website.
  • Before publishing marketing materials, ensuring they are accessible to all audiences.
  • As part of a broader accessibility review process for digital assets.

Key capabilities

  • Text contrast analysis
  • Font size validation
  • Alternative text (alt text) assessment for images

Example prompts

  • "Audit the perceivable aspects of this webpage: [URL]"
  • "Check the text contrast and font sizes on this document."
  • "Analyze the alt text provided for these images: [list of image URLs/descriptions]"

Tips & gotchas

This skill provides a preliminary assessment. A full WCAG audit requires more in-depth testing with assistive technologies and user feedback.
