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 janjaszczak/cursor at cb70ff7aec.

    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, Vanilla Web, enables AI agents to generate simple web pages using only HTML, CSS, and JavaScript – without relying on any frameworks like React, Vue, or Angular. It focuses on creating small UI components such as modals, tabs, dropdowns, and form validation directly within the Document Object Model (DOM). The goal is to produce complete, runnable files with clear instructions for local execution and verification.

When to use it

  • When you need a basic user interface element built without any JavaScript frameworks.
  • To refactor existing codebases to remove framework dependencies or simplify complex JavaScript.
  • For creating static pages or small UI components where minimal overhead is desired.
  • When explicitly requesting "vanilla JS" or "plain HTML/CSS/JS."

Key capabilities

  • Generates complete, runnable HTML, CSS, and JavaScript files.
  • Adheres to a strict set of guidelines for code structure (ESM modules, Single Responsibility Principle).
  • Prioritizes semantic HTML markup and accessibility best practices (keyboard navigation, focus states).
  • Employs CSS variables for theming and responsive layout techniques.

Example prompts

  • "Create a simple modal dialog using vanilla JavaScript."
  • "Generate a dropdown menu with plain HTML and CSS."
  • "Refactor this existing component to remove the framework dependency."

Tips & gotchas

  • The skill will ask clarifying questions if requirements are ambiguous. Be prepared to provide specific details about your desired outcome.
  • Output is limited to small, testable changes – complex applications may require a more robust solution.
  • Always review the provided "runbook" for instructions on how to run and verify the generated code locally.
