frontend-design

frontend-design is a skill for Claude Code from julianoczkowski/designer-skills. It costs 49 tokens per session (2,639 once invoked), scanned A, original, Apache-2.0.

A frontend-building skill for creating working web pages and components with a deliberate visual style and detailed interface design.

In plain words
What is it for?
Use it to build or refine production web pages, components, and applications when visual quality and consistency matter.
Why use it?
It helps avoid generic-looking interfaces by first examining the existing codebase, design tokens, components, fonts, and layout patterns.

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-design 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill guides creation of distinctive, production-grade frontend interfaces. Implement real working code with exceptional attention to aesthetic detail.

Example prompts

  • "Build the hero section from the brief"
  • "Create a card component in a Scandinavian style"
  • "I want this to feel like a Japanese magazine. Build the layout."
  • "Build the settings page. Use whatever style fits."

Before You Write Any Code

  1. Explore the existing codebase first. Scan specifically for:

    • Component directories: components/, ui/, shared/ and list every component by name and its props/API
    • CSS variables / tokens: files named tokens.css, variables.css, theme.css, or :root declarations with custom properties
    • Tailwind config: tailwind.config.js or tailwind.config.ts, check theme.extend for custom values
    • UI framework themes: Material UI createTheme, Chakra extendTheme, shadcn globals.css and components.json
    • Storybook: .storybook/ directory or *.stories.* files indicating documented components
    • Font loading: Google Fonts links, @font-face declarations, font imports
    • Layout patterns: how existing pages handle grid, containers, breakpoints, and spacing
    • Package.json UI dependencies: tailwindcss, @mui/material, @chakra-ui/react, @radix-ui, lucide-react, framer-motion, etc.
    • If components exist that match or partially match what you need to build, extend or compose them. Do not create duplicates.
  2. Understand the context:

    • What problem does this interface solve? Who uses it?
    • What is the intended emotional tone?
    • What are the hard constraints (framework, devices, performance, accessibility)?
  3. Commit to an aesthetic direction. Either the user names one (see philosophies below) or you choose one that fits the context. State your choice and why before writing code.

Aesthetic Philosophies

When the user names a philosophy or describes a vibe, use these as concrete implementation guides. Each philosophy defines typography, color, layout, spacing, motion, and detail treatment.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
