frontend-analyzer

frontend-analyzer is a skill for Claude Code, Codex from ils15/pantheon-legacy. It costs 24 tokens per session (1,792 once invoked), scanned A, original, MIT.

A code-inspection guide for React components, including React applications built with Next.js. It extracts typography, colors, spacing, layout behavior, component structure, and accessibility details.

In plain words
What is it for?
Use it to document fonts, colors, spacing, responsive layouts, breakpoints, component hierarchies, dark-mode variants, and accessibility attributes.
Why use it?
It helps turn scattered styling and accessibility choices in frontend code into a clearer picture of the interface and its design system.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

frontend-analyzer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Frontend Analyzer

Analisa e identifica tipografia, cores, layout, fontes e elementos de design system em componentes frontend.

Overview

The Frontend Analyzer skill provides deep inspection of frontend code, design elements, and visual properties. It extracts typography, color palettes, spacing systems, component hierarchies, and accessibility attributes from React/Next.js applications.

Core Capabilities

1. Visual Element Analysis

🔤 Typography Detection
  • Font families (system fonts, Google Fonts, custom fonts)
  • Font sizes and scaling systems (rem, px, %)
  • Font weights (100-900)
  • Line heights and letter spacing
  • Text decorations and text transforms
  • Font loading strategies (WOFF2, variable fonts)
🎨 Color Palette Extraction
  • Primary, secondary, accent colors
  • Background and text colors
  • Semantic colors (success, error, warning, info)
  • Opacity/alpha values
  • Color space (RGB, HSL, hex, CSS variables)
  • Dark mode variants
📐 Layout & Spacing
  • Grid systems (CSS Grid, Flexbox)
  • Spacing scale (gaps, margins, padding)
  • Breakpoints and responsive behavior
  • Container queries and fluid sizing
  • Z-index hierarchy
  • Positioning strategies
🧩 Component Architecture
  • Component hierarchy and nesting
  • Reusable component patterns
  • Props and TypeScript interfaces
  • State management patterns
  • Custom hooks usage
  • Styled components vs CSS modules

2. Analysis Categories

  1. Visual Inspection - Screenshots and visual differences
  2. Code Inspection - Component code structure
  3. Design System - Design token usage
  4. Accessibility (A11y) - WCAG AA/AAA compliance
  5. Performance - Font loading optimization

Analysis Output Structure

## 🎨 VISUAL ELEMENTS DETECTED

### Typography System
- Primary Font: [Font family, source, fallback]
- Heading Scale: H1-H6 sizes and weights
- Body Text: Default size, line-height, letter-spacing
- Monospace: Code/terminal fonts

### Color Palette
- Primary: #XXXXXX (RGB, HSL, CSS var)
- Semantic: Success, error, warning colors
- Dark Mode: Color scheme variants
- Contrast Ratios: WCAG AA/AAA compliance

### Layout System
- Grid: [Columns, gap, max-width]
- Breakpoints: [Mobile, tablet, desktop specs]
- Spacing Scale: [Base unit, multipliers]
