Guides the agent to build distinctive, production-grade UIs instead of generic "AI-looking" designs
★ 179k · +1.2k this week · Apache-2.0 · updated 2026-09-29
8.6/10
What it does Frontend Design is one of the skills in Anthropic's official skills repository. It changes how the agent makes visual decisions when it builds or restyles a user interface. Without it, AI-built pages tend to look alike: the same card grids, soft shadows, gradient accents and stock typography. The skill tells the agent to work out the subject,… Read more →
Pros
- Noticeably better-looking UIs
- Loaded only when you build UI, so it costs little context otherwise
Cons
- Taste is subjective; you may still steer it

Drop the file for a brand you want to emulate into your project and tell your coding… Read more →
Pros
- Real, structured design tokens (colour roles, type scale, component states, spacing, shadows, breakpoints) extracted from 73+ live brand sites, not just links o
- Zero setup: copy one DESIGN.md into a project root and reference it in a prompt; each entry ships an HTML colour/type preview to sanity-check it first
- Follows Google Stitch's public DESIGN.md convention, so it works with any AI coding agent that can read a markdown file, not a proprietary format
Cons
- It's a curated reference collection, not executable tooling — value depends entirely on how closely your project matches one of the 73 covered brands
- Tokens are reverse-engineered from public CSS ('as-is, no warranty' per the repo), so treat them as a strong starting point rather than an exact brand-compliant
