Why your Claude sites still look like AI slop

Left on its own, AI design reaches for the safe average: the same fonts, the same purple gradients, the same layout everyone else gets. That’s not a prompting problem, it’s a taste problem, and a prompt alone can’t fix it. A Skill can. It’s a small package of instructions you install once, and it permanently raises the baseline Claude designs from, so the same simple prompt produces something with actual point of view instead of the generic default.

Here are the 5 real skills, the taste stack, what each does, and exactly how it works.

This is Anthropic’s own official skill, built by the team behind Claude itself. Here’s exactly what it does differently: before writing a single line of code, it forces a real aesthetic commitment, brutalist, maximalist, retro-futuristic, luxury, organic, whatever fits, instead of defaulting to the generic AI look. It then implements that specific choice through typography, spatial composition, color theming, and motion, not just surface-level styling.

This one replaces guessing with a real, searchable design database: 67 UI styles, 161 color palettes, 57 font pairings, 99 UX guidelines, and 25 chart types, spread across 22 different tech stacks. Instead of Claude inventing a look from scratch every time, it searches this database and designs from real, tested reference.

Impeccable builds on top of Anthropic’s Frontend Design skill and adds something specific: a shared design vocabulary of 23 real commands, polish, audit, critique, distill, animate, bolder, quieter, so you can direct changes in one word instead of writing a paragraph every time something feels slightly off.

Good motion is what separates a site that feels professional from one that feels like a template, and it’s one of the things AI guesses at worst by default. This skill packages real animation knowledge, GSAP, SVG, Lottie, so Claude builds smooth page transitions and micro-interactions at real 60fps instead of writing shaky, guessed-at animation code from scratch.

Not a design skill exactly, it’s real browser automation, but it solves a specific problem the other four don’t: giving Claude an actual reference. Without it, Claude can only guess at a reference site’s fonts and colors from a screenshot, and that guess is often wrong. With it, Claude can open the real site and read its actual computed styles directly.

A few things to watch for

• Not every skill fits every project. Frontend Design and UI/UX Pro Max have the broadest, most immediate impact, start there.
• These are real, actively maintained community and official repositories as of this guide’s publish date. Skill ecosystems move fast, check the repo itself if it’s been a while since this was written.
• Skills install once and Claude reaches for them automatically after that, on its own, when the work calls for it. You don’t have to name them in every single prompt.

The takeaway

AI doesn’t come with taste, it comes with the average of everything it’s ever seen. Stack these five skills on top and that changes, this is the taste stack, and it fixes the problem at the source instead of fighting it prompt by prompt.
