Boxy

About

Boxy is a zero-radius design system and coding-agent skill that enforces square corners, hairline borders, snapped spacing and a rationed color palette across an interface, installed via a plugin or npx command into an agent's skills folder. It ships with boxy-check, a linter that parses CSS, HTML, JSX, Vue and Svelte and fails the build when code drifts from its rules, which the agent is meant to run before declaring a task done.
