Frontend Design

By anthropics· anthropics/claude-code· 0

Anthropic's official skill for building real, distinctive UIs — not the generic AI default.

Installation

  1. Make sure Claude is on your device and in your terminal.

    Skills load from ~/.claude/skills/ when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then run claude in any terminal to verify.

    One-time setup
    npm i -g @anthropic-ai/claude-code

    Already have it? Skip ahead.

  2. Paste into Claude Code or into your terminal.
    Install

    This copies the whole skill folder into ~/.claude/skills/frontend-design-anthropics/ — the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.

    Faster alternative (instruction-only skills)

    Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.

  3. Restart Claude Code.

    Quit and reopen Claude Code (or any other agent that loads from ~/.claude/skills/). New skills are picked up on startup.

  4. Just ask Claude.

    Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

Prefer to read the source first? Open on GitHub.

When Claude uses it

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

What this skill does

Anthropic's official skill for frontend design. Guides Claude to produce distinctive, production-grade interfaces and steer away from the recognizable "AI slop" aesthetic — purple-blue gradients, generic Inter typography, minimal animations, identical card grids, centered hero sections.

What the skill enforces:

  • Typography: avoid Arial and Inter as defaults. Pick fonts that elevate the brand (Geist, Outfit, Satoshi, Cabinet Grotesk) and respect technical UI conventions (sans-serif only for dashboards, no serifs in software UIs).
  • Motion: use animations purposefully. CSS for static elements, Motion (formerly Framer Motion) for React. Tactile feedback on every interactive element. Stagger entrances. Never animate layout properties — only transform and opacity.
  • Spatial composition: unexpected layouts, asymmetry, overlapping elements, deliberate use of whitespace. Cards only when elevation communicates hierarchy.
  • Color: bounded palettes, one accent color, tinted neutrals. Saturation caps for brand cohesion.
  • Interaction states: every component ships with loading, empty, error, and success states — not just the happy path.

Most-installed Claude skill (277k+ installs at the time of import). Ships with Anthropic's Claude Code plugin and is the de facto starting point for any frontend project.
