canvas-ui is a design skill for AI coding agents. It explores genuinely different directions, puts them on a live canvas you can squint at and tune, and then checks the real render, not the code.
npx skills add riz007/canvas-uiEach direction is a card with a north star, an engine and five tone dials, not a list of adjectives.
Colors, type scale, spacing, radius and motion are generated from the card. Text contrast passes AA by construction.
Compare, squint, go blind, tune the dials live, then Pick. Your notes and tweaks are copied as one instruction.
Every screenshot is linted for legibility bugs and AI-default tells, then reviewed by an agent that never saw the build.
