How do I install Frontend Design System?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Frontend Design System with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 8.8/10
Tested: Jul 17, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 322a34f

Built the same hero section twice: my no-skill default landed on Inter, a purple-to-pink gradient and a centered symmetric layout, hitting four of the anti-patterns the skill explicitly names. The skill-guided version used a DM Serif Display / DM Sans pairing, a warm-white plus terracotta palette lifted from its themes.md, a 5:7 asymmetric grid and an offset-shadow button, clearing all four. A guidance-only skill with a genuinely visible delta; the 189-line themes.md and 351-line components.md are real, concrete references, not filler.

What Frontend Design System does

A design-guidance skill that names the AI-slop anti-patterns (Inter font, purple-pink gradients, symmetric hero, even 3-column grids) and supplies concrete alternatives: serif/sans font pairings, non-default palettes, asymmetric layouts and restrained motion. Triggers when building landing pages, dashboards or UI components. Bundles themes.md and components.md with ready CSS.
