Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Impeccable CLI

Detect UI anti-patterns and design quality issues from the command line. Scans HTML, CSS, JSX, TSX, Vue, and Svelte files for 25 specific patterns including AI-generated UI tells, accessibility violations, and general design quality problems.

Quick Start

# Install skills into your AI harness (Claude, Cursor, Gemini, etc.)
npx impeccable skills install

# Update skills to the latest version
npx impeccable skills update

# List all available commands
npx impeccable skills help

# Scan files or directories for anti-patterns
npx impeccable detect src/

# Scan a live URL (requires Puppeteer)
npx impeccable detect https://example.com

# JSON output for CI/tooling
npx impeccable detect --json src/

# Regex-only mode (faster, no jsdom)
npx impeccable detect --fast src/

What It Detects

AI Slop Tells: patterns that scream "AI generated this":

  • Side-tab accent borders, gradient text on headings
  • Purple/violet gradients and cyan-on-dark palettes
  • Dark mode with glowing accents, border + border-radius clashes

Typography Issues: overused fonts (Inter, Roboto), flat type hierarchy, single font families

Color & Contrast: WCAG AA violations, gray text on colored backgrounds, pure black/white

Layout & Composition: nested cards, monotonous spacing, everything-centered layouts

Motion: bounce/elastic easing, layout property transitions

Quality: tiny body text, cramped padding, long line lengths, small touch targets

25 detections in total. See the full list at impeccable.style.
