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: 7.6/10

Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · 7fffa5e

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 29, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Built the same sign-in card twice, once plain and once under the bundled neumorphism guideline: the guided file carried 11 design tokens against zero, put all six spacing values on the 8px grid (the plain one hit it 0 of 6), and gave every control a 44px target plus a focus ring. The same measurement exposed a contradiction inside the guideline — its primary-CTA rule (theme-colour label on a tinted surface) computes to 2.94:1 contrast, under the 4.5:1 its own final checklist demands, and worse than the plain version's 3.7:1. Step 2 of the skill points at references/meterial-design.md, a file that does not exist (the real one is material-design.md), though the correct name appears in the table above it. Expect a hard stop for two questions — style and hex colour — before any output appears.

What Design System Is All You Need does

Bundles eight written design guidelines — neumorphism, glassmorphism, brutalism, skeuomorphism, Material, neon, heritage and the author's own 'pnalism' — each with common rules, per-component specs and a token system derived from just a theme colour and an intensity keyword. Triggers on UI work: building pages, dashboards, cards, forms or any frontend component, in HTML/CSS, React, SwiftUI or Compose. It stops and asks which style and which hex colour before it writes anything.

How to install Design System Is All You Need

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
