useVyre

AI-native design system for humans and agents. Built on semantic CSS variables — no runtime magic, no hallucinations.

Why useVyre?

Most design systems were built for humans reading documentation. useVyre is built for both — every naming convention, token structure, and component API is designed so that AI coding agents (Claude, Cursor, Copilot, Windsurf) can generate correct, consistent UI without guessing.

Problem	useVyre solution
AI hallucinates component props	Every component has an inline AI context block
AI uses raw color values	Semantic tokens replace all raw colors
AI generates inconsistent spacing	4px grid enforced via spacing tokens
AI doesn't know valid variants	`data-variant` API is explicit and enumerated
Design system only works in one framework	CSS variables work everywhere

Packages

Core

Package	Version	Downloads	Description
`@usevyre/tokens`			DTCG-compliant design tokens → CSS variables, JS/TS, JSON
`@usevyre/react`			React + TypeScript components
`@usevyre/vue`			Vue 3 + TypeScript components
`@usevyre/init`			One-command setup CLI (`npx @usevyre/init`)
`@usevyre/all` · `react-all` · `vue-all`	—	—	Convenience meta-packages (tokens + components in one install)

AI tooling

Package	Version	Downloads	Description
`@usevyre/ai-context`			Machine-readable component schema for LLM system prompts
`@usevyre/mcp-server`			MCP server — gives agents live access to the component schema
`@usevyre/eslint-plugin`			Lints for invalid variants, raw colors, hallucinated props
`@usevyre/validate-ai-context`			CI check that the AI context stays in sync with components
`@usevyre/prompt-templates`			Ready-made prompts for generating UI with useVyre

Components

40+ production-ready components for React and Vue — buttons, forms (Input, Field, Radio, Checkbox, Select), overlays (Modal, Sheet, Popover, Tooltip), data (DataGrid, Table, Pagination), layout (Sidebar/AppLayout, Card, Tabs), and richer pieces like Kanban, Conversation (chat), DateRangePicker, and a zero-dependency RichTextEditor — plus more on the way.

Every component ships with an inline AI-context block, a machine-readable schema entry, and documented anti-patterns.

Quick Start

bash

# React
npm install @usevyre/tokens @usevyre/react

# Vue 3
npm install @usevyre/tokens @usevyre/vue

// Import once at your app entry point
import "@usevyre/react/styles";   // tokens + component styles (one import)

import { Button, Card, DataGrid } from "@usevyre/react";

Examples

Real, multi-page layouts built entirely from useVyre components:

Dashboard app — functional 5-page billing dashboard with working sidebar navigation
Sign-in — auth form with validation

Design Principles

Semantic over primitive — --vyre-color-semantic-accent not --amber-400
Explicit over implicit — every valid value is documented inline
Zero runtime — pure CSS variables, works in any framework
AI-first naming — token names describe intent, not appearance
Copy-paste friendly — no mandatory build setup, just import CSS and go

Local Development

Run the docs site locally to browse all component examples and live demos.

Prerequisites: Node.js ≥ 18, pnpm ≥ 9

bash

# 1. Clone and install
git clone https://github.com/gapra/usevyre.git
cd usevyre
pnpm install

# 2. Build design tokens (required — components import CSS variables from here)
pnpm --filter @usevyre/tokens build

# 3. Start the docs dev server
pnpm --filter @usevyre/docs dev

Open http://localhost:4321 in your browser.

Shortcut — tokens build + dev server in one command:
