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 ynulihao/agentskillos at c3cfae10ea.

    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 optimizes frontend performance. It allows for identifying and resolving bottlenecks in web applications, leading to faster load times and improved user experience. The skill focuses on improving rendering speed and reducing resource consumption within a browser environment.

When to use it

  • When users report slow page loading or unresponsive interactions on your website.
  • During performance audits as part of a regular maintenance schedule for web applications.
  • Before launching new features or redesigns to ensure they don't negatively impact performance.
  • To address issues flagged by browser developer tools regarding rendering times and resource usage.

Key capabilities

  • Frontend Performance Optimization
  • Rendering Speed Improvement
  • Resource Consumption Reduction
  • Bottleneck Identification

Example prompts

  • "Analyze the frontend performance of [website URL] and suggest optimizations."
  • "Identify bottlenecks causing slow loading on this page: [page URL]."
  • "How can I reduce the rendering time for a complex component in my React application?"

Tips & gotchas

The skill's effectiveness relies on providing accurate URLs or code snippets related to the frontend you want optimized. It is most effective when used with existing, functional web applications rather than theoretical designs.
