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 erichowens/some_claude_skills at 6713fc7a64.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

The color-contrast-auditor skill analyzes web pages to identify text and background color combinations that fail accessibility standards. It specifically checks if foreground and background colors meet the required contrast ratios for readability, helping developers ensure their interfaces are inclusive for users with visual impairments.

When to use it

  • Audit existing landing pages before public release to catch low-contrast text errors early.
  • Validate form labels, button text, and error messages against WCAG guidelines.
  • Test dark mode implementations where color inversion often leads to insufficient contrast.
  • Integrate into the development workflow to automatically flag accessibility issues during UI updates.

Key capabilities

  • Scans web pages for text elements with poor visibility against their backgrounds.
  • Calculates specific contrast ratios between foreground and background colors.
  • Highlights non-compliant areas that violate standard accessibility thresholds.

Example prompts

  • "Run a color-contrast audit on my current homepage and list any text elements failing WCAG AA standards."
  • "Identify all buttons with low contrast ratios so I can adjust their styling for better accessibility."
  • "Check the error messages on my login form to ensure they are readable against the background."

Tips & gotchas

Ensure your AI agent has access to the live URL or a snapshot of the page being audited, as it cannot analyze local files directly. While this tool highlights contrast issues, it does not replace a full manual accessibility review which includes other factors like semantic HTML and focus states.
