Install target

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 serkan-ozal/browser-devtools-skills at 62b9f7990f.

    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 allows an AI agent to perform a performance audit of a web page using browser developer tools. It analyzes metrics like CPU usage, memory consumption, and rendering times to identify potential bottlenecks and areas for optimization. The resulting report provides actionable insights for improving website speed and user experience.

When to use it

  • Troubleshooting slow loading pages: Identify why a specific webpage is taking too long to load for users.
  • Optimizing web application performance: Regularly assess the performance of a web application to ensure responsiveness and efficiency.
  • Analyzing mobile website speed: Evaluate how a website performs on mobile devices, considering factors like network conditions and device capabilities.
  • Comparing different versions of a webpage: Determine which version of a webpage (e.g., A/B test variations) offers the best performance.

Key capabilities

  • Browser DevTools integration
  • CPU usage analysis
  • Memory consumption tracking
  • Rendering time measurement
  • Performance report generation

Example prompts

  • "Run a performance audit on https://www.example.com and tell me what's slowing it down."
  • "Analyze the CPU usage of this webpage: https://www.mywebsite.com/checkout."
  • "Generate a performance report for my landing page, highlighting areas where I can improve loading speed."

Tips & gotchas

This skill requires access to a browser environment with developer tools capabilities. The accuracy of the audit depends on the stability and reliability of the underlying browser instance.
