+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Workflow Requirements
+
+- **Always create a Linear ticket** for all work before starting
+- **Always create a new PR** for all changes - do not commit directly to main
+
+## Project Overview
+
+@seamapi/react is a React component library for Seam smart device management. It provides white-labeled UI components for device management, access codes, and thermostat controls. Components are available as React components and as native Web Components.
+
+## Tech Stack
+
+- **React 18+** with TypeScript
+- **Vite** for building elements bundle
+- **tsc/tsc-alias** for TypeScript compilation
+- **Vitest** with happy-dom for testing
+- **Storybook 7** for component development
+- **SCSS** for styling (compiled with Sass)
+- **@tanstack/react-query** for data fetching
+- **@seamapi/http** for Seam API communication
+- **@seamapi/react-query** for query hooks
+
+## Essential Commands
+
+```bash
+npm start          # Start Storybook development (runs examples + storybook)
+npm run build      # Build the library (JS + CSS + elements)
+npm test           # Run tests with Vitest
+npm run test:watch # Run tests in watch mode
+npm run lint       # Run ESLint + Prettier + Stylelint
+npm run format     # Auto-fix linting issues
+npm run typecheck  # Run TypeScript type checking
+npm run storybook  # Run Storybook only
+npm run examples   # Run example apps
+npm run generate   # Generate icon components from SVGs in assets/icons
+```

+
+## Key Architecture Patterns
+
+### Component Structure
+
+Each component typically has:
+
+- `ComponentName.tsx` - Main component implementation
+- `ComponentName.element.ts` - Web Component wrapper
+- `ComponentName.stories.tsx` - Storybook stories
+- `ComponentName.test.tsx` - Component tests (optional)
+
+### Entry Points
+
+- `@seamapi/react` - Full library (components + hooks)
+- `@seamapi/react/hooks` - Hooks only (lighter bundle)
+- `@seamapi/react/elements` - Web Components bundle
+
+### Path Aliases
+
+- `lib/*` → `./src/lib/*`
+- `fixtures/*` → `./test/fixtures/*`
+- `@seamapi/react` → `./src/index.ts`
+
+## Code Style
+
+- ESLint with standard-with-typescript config
+- Prettier for formatting
+- Stylelint for SCSS
+- Import sorting via eslint-plugin-simple-import-sort
+- Require `.js` extensions in imports (ES modules)
+- Use inline type imports: `import { type Foo } from 'bar.js'`
+- All CSS classes are prefixed with `seam-`
+
+## Testing
+
+Tests use Vitest with happy-dom environment. Test fixtures are in `test/fixtures/`.
+
+```bash
+npm test              # Run all tests
+npm run test:update   # Update snapshots
+npm run test:ui       # Open Vitest UI
+```
+
+## Fake Seam Connect
+
+The project uses @seamapi/fake-seam-connect for deterministic testing and Storybook development. Seed data is in `.storybook/seed-fake.js`.
+
+## Publishing
+
+- Automatic releases via semantic-release based on Angular commit message conventions
+- Manual releases via GitHub Actions workflow dispatch
