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
Scanned jovermier/cc-stack-marketplace at a14c3b9a25.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill
What it does
This skill focuses on optimizing Next.js applications for improved performance. It provides tools and techniques to reduce bundle sizes, optimize image loading, and enhance overall application speed. The skill aims to deliver a faster and more responsive user experience by addressing common Next.js performance bottlenecks.
When to use it
- Slow page load times: When users are experiencing noticeable delays when navigating your Next.js website.
- Large bundle sizes: If your Next.js application's JavaScript bundles are excessively large, impacting initial load time.
- Image optimization needs: When you want to ensure images on your site are properly optimized for web delivery (e.g., correct format, resolution).
- Performance regression testing: To proactively identify and address performance issues during development cycles.
Key capabilities
- Bundle size reduction techniques
- Image optimization strategies
- Next.js performance profiling tools
- Code splitting implementation
Example prompts
- "Analyze my Next.js application for potential performance bottlenecks."
- "Suggest ways to reduce the bundle size of my Next.js app's homepage."
- "Optimize the images on this page in my Next.js project."
Tips & gotchas
This skill requires a working Next.js project to be effective. The agent may require access to your codebase or deployment environment for comprehensive analysis and optimization suggestions.
