Impeccable UI Reviewer

A read-only design-engineering reviewer for frontend changes. It evaluates your UI the way a senior product designer would and returns specific, actionable fixes.

What it checks

Spacing & rhythm — inconsistent padding, magic numbers, broken vertical rhythm
Visual hierarchy — type scale, weight, and emphasis that don't guide the eye
Accessibility — contrast ratios, focus states, hit targets, semantics
Motion — transitions that are too slow, janky, or distracting
Consistency — drift from your design tokens and component patterns

Why it's safe to run

Requests only readFiles. It cannot write to your files, run commands, or reach the network — every suggestion is yours to apply.
