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 oakoss/agent-skills at 85e3a3919d.

    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

The oakoss-performance-optimizer skill analyzes frontend code and suggests optimizations to improve website loading speed and overall user experience. It identifies potential bottlenecks such as inefficient JavaScript, large image sizes, and unoptimized CSS. The tool provides actionable recommendations for developers to enhance performance metrics.

When to use it

  • Slow Website Loading: Use this when users are complaining about slow page load times or bounce rates are high.
  • Mobile Optimization: Employ the skill before launching a mobile-first website or app to ensure optimal performance on smaller devices.
  • Performance Audits: Integrate into regular development workflows for proactive identification and resolution of performance issues.
  • Refactoring Legacy Code: Utilize during refactoring efforts to identify and address performance bottlenecks in older codebases.

Key capabilities

  • JavaScript optimization suggestions
  • Image size reduction recommendations
  • CSS optimization advice
  • Performance bottleneck identification

Example prompts

  • "Analyze this website's frontend for performance issues: [website URL]"
  • "Suggest optimizations to improve the loading speed of my JavaScript bundle."
  • "Identify large images on this page and recommend compression strategies."

Tips & gotchas

The skill’s effectiveness relies on accurate code analysis. Ensure the provided codebase is complete and representative of the website's functionality for best results.
