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 jabranr/css-best-practices at 54dd594e74.

    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 provides guidance and recommendations for writing clean, maintainable, and efficient CSS. It helps ensure code adheres to established best practices, promoting consistency and reducing technical debt within a project. The skill can be used to refactor existing CSS or generate new CSS from scratch.

When to use it

  • You're starting a new frontend project and want to establish strong coding standards early on.
  • An existing codebase has inconsistent or poorly structured CSS that needs cleaning up.
  • You need help understanding the rationale behind specific CSS best practices.
  • You are generating CSS from design specifications and want to ensure it follows established conventions.

Key capabilities

  • Provides recommendations for CSS structure and organization.
  • Offers guidance on selector specificity and cascading rules.
  • Suggests techniques for writing efficient and maintainable CSS.
  • Promotes adherence to common CSS best practices.

Example prompts

  • "Generate CSS for a button component, following best practices for styling and accessibility."
  • "Explain the importance of using BEM in CSS development."

Tips & gotchas

The skill's effectiveness depends on providing clear and concise CSS code snippets or descriptions. It is most useful when applied to specific sections of CSS rather than entire stylesheets at once.
