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 hack23/cia at bd3035e5a3.

    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, hack23-performance-optimization, helps AI agents optimize frontend web application performance. It focuses on identifying and resolving bottlenecks that impact loading times and responsiveness. Specifically, it can analyze code and suggest improvements for areas like JavaScript bundling and image optimization.

When to use it

  • Slow website load times: When users complain about a sluggish website or app.
  • High bounce rate: To investigate if slow performance is driving visitors away.
  • Poor mobile experience: Optimizing for slower mobile networks and devices.
  • Large JavaScript bundles: Reducing the size of JavaScript files to improve initial load time.

Key capabilities

  • JavaScript bundling analysis
  • Image optimization suggestions
  • Performance bottleneck identification
  • Frontend code review for performance issues

Example prompts

  • "Analyze this website's frontend and suggest ways to improve its loading speed."
  • "Review my JavaScript bundle size and recommend optimizations."
  • "Identify any potential performance bottlenecks in this React component."

Tips & gotchas

This skill is most effective when provided with access to the relevant codebase or a URL of the website being analyzed. The agent may require specific build tools or configurations for accurate assessment.
