Automated safety checks
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

About this skill
What it does
This skill optimizes frontend performance. It analyzes web pages to identify and suggest improvements for loading times, rendering efficiency, and overall user experience. The skill aims to reduce resource consumption and improve responsiveness on various devices and network conditions.
When to use it
- Slow website: When users report slow page load times or sluggish interactions.
- Mobile optimization: To ensure a smooth experience for mobile users with limited bandwidth.
- Large image files: To identify opportunities for compressing or optimizing large images impacting performance.
- Complex JavaScript: To analyze and suggest improvements to complex JavaScript code that might be slowing down the page.
Key capabilities
- Performance analysis
- Image optimization suggestions
- JavaScript efficiency recommendations
- Loading time reduction strategies
Example prompts
- "Analyze this website [URL] for performance bottlenecks."
- "Suggest ways to optimize image loading on [URL]."
- "What JavaScript code changes can improve the responsiveness of [URL]?"
Tips & gotchas
The skill's recommendations should be reviewed and tested thoroughly before implementation, as some optimizations might have unintended consequences. Consider the trade-offs between performance gains and potential impact on visual fidelity or functionality.
