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 andronics/claude-plugin-css-pro at 06be89aff3.

    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.

When to use it

  • Auditing existing websites: Check a website's current HTML for common accessibility problems before making changes.
  • Validating new code: Integrate the skill into your development workflow to catch accessibility issues early on.
  • Troubleshooting user complaints: Investigate specific accessibility concerns raised by users of a web application.
  • Ensuring compliance: Verify that a website meets required accessibility standards for legal or regulatory reasons.

Key capabilities

  • HTML Accessibility Analysis
  • WCAG Compliance Checking
  • Image Alt Text Detection
  • Heading Structure Validation
  • Color Contrast Evaluation

Example prompts

  • "Analyze this HTML snippet for accessibility issues: [paste HTML code]"
  • "Check the heading structure of this webpage and suggest improvements."
  • "Does this image have appropriate alternative text? [provide link to image]"

Tips & gotchas
