shadcn/ui-Based UI Kit for AI Prototypes in Claude Code and Cursor

X postChris HalaskaTool

Chris Halaska has released a UI kit tailored for founders vibe-coding AI products. Built on top of shadcn/ui, it introduces custom visual styling and AI-focused UX patterns that can be applied by copying a single prompt into Claude Code or Cursor.

Key points

  1. Built on shadcn/ui, adding distinct visual direction and specialized UX patterns for AI interfaces.
  2. Implemented by copying a single prompt directly into AI coding tools such as Claude Code or Cursor.
  3. Currently in beta, with additional patterns planned from ongoing studio work.
  4. The author notes the kit aims to push prototypes further than out-of-the-box defaults rather than solving every edge case.

Why it matters

During AI-assisted prototyping, products frequently rely on default component appearances. A prompt-based kit provides a rapid shortcut to bring cohesive UI styling and purpose-built interaction patterns to early-stage software without heavy design setup.

Analysis

This project illustrates how design system delivery is shifting towards prompt injection for coding agents. Rather than configuring components manually, developers give guidelines directly to Cursor or Claude Code. However, prototypes that quickly outgrow the supplied patterns will still require manual UX refinement.

We designed a UI kit for founders vibe-coding AI products. It sits on shadcn/ui, a solid foundation most of these tools already reach for. We've added our own visual direction and the UX patterns AI products need. Copy one prompt into Claude Code or Cursor and your prototype t.co/vdYMZhdHqk

  1. It's in beta. We'll keep adding patterns as studio work surfaces them. If you try it, we'd like to see the result. Send us what it did to your screens, good or bad.
  2. @fhlcreative Thanks Phil! still a wip

  • @fhlcreative @chalaska Love this!
  • @everywhereayush @chalaska Its great A small thing I noticed is that AI chat section where the container width is more than the AI input box which feels a bit off. Why because in most AI apps the messaging container is of the same width as input box. I might be wrong but I think you should look into it.
  • @letdarky @chalaska the demo UI is bad even in the after view.
  • @fhlcreative @chalaska I'm giving it a try right now on one of my projects...
  • @camduncalfe @chalaska Clean!
