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 warpdotdev/oz-skills at 6c08c49fc6.

    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 performs a comprehensive audit of a website's performance, identifying areas for improvement. It analyzes metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) to pinpoint bottlenecks impacting user experience. The analysis provides actionable recommendations to optimize loading times and overall site speed.

When to use it

  • Troubleshooting slow websites: Diagnose why a website is performing poorly for users.
  • Pre-launch performance checks: Evaluate the performance of a new website before its public release.
  • Identifying optimization opportunities: Discover specific areas within a website that can be improved for better speed.
  • Post-optimization validation: Verify if changes made to improve website performance have had the desired effect.

Key capabilities

  • Analyzes LCP, FID, and CLS metrics.
  • Identifies performance bottlenecks.
  • Provides actionable optimization recommendations.

Example prompts

  • "Perform a web performance audit on example.com."
  • "Analyze the website at mydomain.net for slow loading times."
  • "Give me an audit report of the performance of this URL: https://www.example.org/page1"

Tips & gotchas

The skill requires a valid URL to analyze. Results are based on automated analysis and may require further investigation by a human expert for complete accuracy.
