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 schalkneethling/webdev-agent-skills at 85710096f4.

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

About this skill

What it does

This skill enables AI agents to generate and manipulate HTML documents that adhere to semantic standards, ensuring code is both accessible and logically structured. It focuses on creating meaningful markup rather than relying solely on presentational elements.

When to use it

  • Building web pages where screen reader compatibility and SEO are critical priorities.
  • Developing applications requiring strict adherence to W3C accessibility guidelines.
  • Creating content that needs clear hierarchical structure for search engine indexing.
  • Refactoring legacy codebases to improve maintainability and compliance.

Key capabilities

  • Generates valid, semantic HTML5 markup elements (e.g., <article>, <nav>, <main>).
  • Ensures proper document structure including <!DOCTYPE>, <html>, <head>, and <body> tags.
  • Supports language declaration via the lang attribute for internationalization.
  • Includes necessary meta tags for viewport settings, character sets, and social sharing (Open Graph/Twitter Cards).

Example prompts

  • "Create a semantic HTML structure for a blog post layout including navigation, main content area, and footer."
  • "Generate an accessible HTML form with proper labels and semantic field groups for user registration."
  • "Write the head section of an HTML document optimized for SEO with Open Graph tags for social media sharing."

Tips & gotchas

Ensure your AI agent has access to current HTML5 specifications to avoid deprecated attributes. While this skill focuses on structure, you may need additional skills to inject CSS or JavaScript for full functionality.
