* feat(detector): flag italic-serif display heroes and uppercase eyebrow chips (#127) Two new rules covering the structural tells of late-2025/early-2026 AI-generated marketing pages. - italic-serif-display: oversized italic serif (Fraunces, Recoleta, Newsreader, Playfair, Cormorant, Tiempos, ...) as the primary hero headline. Anchored on h1 (or h2 at >= 48px) with font-style: italic and a serif primary face. - hero-eyebrow-chip: uppercase letter-spaced label sitting as the previousElementSibling of a hero h1 (font-size >= 48px). Bounded text length 2-30 chars, letter-spacing >= 1.6px, font-size <= 14px. The pill-chip variant (background + border-radius: 999px) falls out of the same gates for free. Both follow the existing icon-tile-stack pattern: pure check function + browser DOM adapter + jsdom adapter, wired into both element loops. Two-column fixtures (4 flag / 6 pass each) drive the jsdom tests. Skill copy in source/skills/impeccable/reference/typography.md and critique.md calls out the patterns by name. The italic-serif rule's description acknowledges that editorial/magazine register may legitimately want the pattern -- judge by context.

# Impeccable CLI
|
|
|
|
Detect UI anti-patterns and design quality issues from the command line. Scans HTML, CSS, JSX, TSX, Vue, and Svelte files for 27 specific patterns including AI-generated UI tells, accessibility violations, and general design quality problems.
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
# 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
|
|
|
|
