Frontend Design
An official Anthropic skill that directs Claude to build distinctive, production-grade web UIs — prioritizing bold visual identity over generic defaults.
This skill is for developers and designers who want UIs that actually look designed, not like every other app using the same component library defaults.
What This Skill Does
Core Capabilities
- Design Direction First: Establishes a bold conceptual direction before writing any code, based on purpose, tone, and constraints
- Avoids Generic Defaults: No overused fonts (Arial, Inter), no cliché color schemes, no cookie-cutter layouts
- Unexpected Layouts: Asymmetry, overlap, diagonal flow, generous negative space
- Scroll Interactions: Staggered reveal animations and scroll-triggered effects
- Atmosphere-Driven Backgrounds: Gradients, textures, layered visual effects
- Calibrated Complexity: Matches code complexity to aesthetic ambition — maximalist or minimalist as needed
How It Works
Before writing a single line of code, this skill asks:
- What is the purpose and tone of this interface?
- What constraints exist (brand, platform, audience)?
- What visual direction would make this feel intentional rather than default?
Only after establishing that direction does it move into implementation.
Example Use Cases
- "Build a landing page for my SaaS product"
- "Create a dashboard component with a dark, data-dense aesthetic"
- "Design an onboarding flow that feels premium"
- "Redesign this form to feel less corporate"
- "Build a portfolio site with strong visual identity"
Design Principles
Layout
- Asymmetry over symmetry where it serves the composition
- Overlap elements to create depth and visual tension
- Diagonal flow and off-grid placement for energy
- Generous negative space to let content breathe
Typography
- Avoids default system fonts and overused choices
- Uses type as a design element, not just content delivery
- Creates clear hierarchy through contrast, not just size
Animation
- Staggered reveals that feel intentional
- Scroll-triggered interactions that enhance, not distract
- Transitions calibrated to the overall aesthetic tone
Backgrounds & Atmosphere
- Layered gradients for depth
- Textures to add tactility
- Visual effects that reinforce the conceptual direction
