SkillMedia

antfu-design is a skill that gives your AI a set of design conventions for building and refactoring interfaces with UnoCSS. Once added, your AI can style tooling and devtools UIs with consistent class-based semantic tokens in both light and dark modes, and apply polish to landing pages and product surfaces.

Available today. Use it from your connected AI after setup.

After adding it, ask your AI to build or refactor an interface with UnoCSS. It will follow the conventions as it works.

Then ask your AI: use the antfu-design skill

What your AI can do with it

  • Build or refactor UnoCSS interfaces that follow the antfu design conventions
  • Apply class-based semantic tokens with light and dark variants
  • Keep tooling and devtools UIs consistent across both modes
  • Add micro-interaction polish to landing pages and product surfaces
  • Read existing designs and fix low-quality patterns

What this skill tells your AI

The instructions your AI receives, as published by antfu/skills in skills/antfu-design/SKILL.md and read by ahel’s review.

Use this when building interfaces with UnoCSS in any framework (React, Vue, Svelte, Solid, or plain HTML), from dense devtools panels to landing pages. Read core-design-read first to set the direction, then apply the token system plus the polish and anti-slop rules.

Core Rules

  • Use semantic shortcuts (bg-base, border-base, color-active, btn-action) instead of raw utility chains in markup.
  • Design light and dark mode together. Core tokens must work in both themes.
  • Name z-index layers (z-top-nav, z-panel-content, z-drawer-content). Do not use raw z values in templates.
  • Generate class-based utilities only (class="..."). Avoid Attributify syntax in generated code.
  • Keep icon/status class strings literal so UnoCSS can statically extract them (// @unocss-include when needed).
  • Use font-mono + tabular-nums for technical values (paths, SHAs, counters, timestamps, percentages).
  • For long paths and IDs, truncate visually but keep the full value in title.
  • Read the brief and set the three dials before choosing a look (core-design-read).
  • Borders for dense or structural surfaces, layered shadows for elevated ones (features-micro-interactions).
  • Zero em-dash and en-dash characters in any user-facing text (best-practices-anti-slop).

Starter shortcuts

A minimal semantic core. See core-starter-kit for the full uno.config.ts and base styles.
