UI UX Pro Max

UI UX Pro Max (ui-ux-pro-max) is a skill by Next Level Builder that gives coding agents a searchable design database: UI styles, color palettes, font pairings, UX guidelines and chart types, across stacks from React and Next.js to SwiftUI, React Native and Flutter.

Verdict

6/10

My score

It gives the agent a design direction it wouldn't pick on its own and adds more product detail, but the result still has tell-tale AI touches, it doesn't trigger by itself, and it doubles the time and cost.

Tested · v2.5.0

Pros

  • Picks a design direction for the product type, instead of the agent's default look.
  • Adds product-specific detail: in the test, a progress grid, notification previews and a monthly/yearly price toggle.
  • One install covers web and mobile stacks, from React and Next.js to SwiftUI and Flutter.
  • The rounded, pill-shaped buttons look good.
  • Free and MIT licensed.

Cons

  • Parts of it still look AI-made: notification cards floating over the phone mockup and covering its content, and soft color blobs in the corners that end in hard edges.
  • Didn't trigger on its own in the test. I had to name it in the prompt.
  • Took twice as long and cost twice as much as the same task without it.
  • Needs Python 3, since the design search runs as a script.
Best for
Starting a new landing page or app screen when you don't have a design direction yet.
Skip it if
You already have a design system or a Figma file to build from.

The test

Same task, both runs

Build a landing page for Streak, a habit-tracking iPhone app. Write it as a single self-contained index.html file in the current directory (inline CSS, no external images). Include a hero, three features, pricing, and a footer.

Streak landing page built with the skill: warm cream background, amber headline, phone mockup with floating cards

What I found

  • On the first try the skill was installed but never used. The agent wrote the page directly.
  • When named, it ran its design search and chose an App Store-style page with soft "clay" cards and an amber accent, instead of the default dark theme.
  • The result had more product detail and nicer rounded buttons, but kept two common signs of AI-made pages: floating cards stacked on the phone mockup (covering its text) and corner gradient blobs with hard, cut-off edges.
  • The page without the skill was already polished, so the difference is direction and detail, not broken versus fixed.

How I ran it: Claude Code 2.1.306 with Claude Opus, run headless twice with only Claude Code's built-in skills loaded (no user skills, plugins or MCP servers). The second run had ui-ux-pro-max installed in the project and its prompt started with "Use the ui-ux-pro-max skill." Screenshots taken in Chrome at 1440×900 and 390×844 with reduced motion on.

What it does

  • Searches a database of 50+ UI styles, 161 color palettes and 57 font pairings for ones that fit the product you're building.
  • Applies 99 UX guidelines and reasoning rules for 161 product types, so a dashboard and a landing page get different advice.
  • Covers 25 chart types and stack-specific guidance for React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind and shadcn/ui.
  • Reviews existing UI code for accessibility, consistency and interaction states.

When to use it

Use it at the start of a new page or app, before any components exist, so the agent picks a style, palette and type pairing on purpose instead of falling back to defaults. It's also useful for a review pass on a screen that works but looks generic.
