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 mindrally/skills at 7682ca7771.

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

About this skill

The postcss-best-practices skill provides AI agents with access to industry-standard guidelines for configuring and optimizing PostCSS workflows. It ensures that CSS processing pipelines adhere to established conventions for maintainability, performance, and compatibility across modern web projects.

When to use it

  • Configuring build tools like Webpack or Vite to process CSS files efficiently using PostCSS plugins.
  • Enforcing consistent naming conventions and syntax rules within a team's stylesheet architecture.
  • Resolving browser compatibility issues by automatically applying polyfills or modernizing legacy CSS features.
  • Streamlining the integration of new CSS methodologies like BEM or utility-first frameworks into existing codebases.

Key capabilities

  • Access to recommended PostCSS plugin configurations for common tasks such as autoprefixing and minification.
  • Guidance on structuring postcss.config.js files for optimal toolchain integration.
  • Best practices for managing dependencies and avoiding conflicts between multiple CSS processors.

Example prompts

  • "Generate a postcss.config.js file that applies Tailwind CSS, Autoprefixer, and CSSnano to my project."
  • "What are the recommended PostCSS plugins for ensuring cross-browser compatibility in a React application?"
  • "Explain how to configure PostCSS to handle SCSS preprocessing alongside standard CSS transformations."

Tips & gotchas

Ensure your build environment has Node.js installed before attempting to install or run PostCSS configurations. While this skill outlines best practices, specific plugin requirements may vary depending on the complexity of your project's existing CSS architecture.
