What does baseline-ui do?
baseline-ui is a skill that applies a fixed set of UI rules to clean up interfaces that look AI-generated. Called alone, it holds all UI work in the chat to those rules. Called with a file, it lists each violation with the quoted line, a one-sentence reason and a code fix. The rules expect Tailwind defaults, the cn helper, motion/react for JS animation and accessible primitives such as Base UI, React Aria or Radix. They ban gradients, glow effects, h-screen and custom easing, cap feedback animation at 200ms, and animate only transform and opacity. Typography rules ask for text-balance on headings and tabular-nums for data.
When should you use baseline-ui?
Use it when
- A generated page has messy spacing and type
- You want a file checked against fixed UI rules
- You are adding animation and want limits on it
Skip it when
- Your project does not use Tailwind
- You want gradients, glows or expressive motion
What it needs and what it can touch
You need
- A project using Tailwind CSS
What it can do
- Reads the file you name and suggests code changes
From reading its instructions, not from running it.
