Rcr Frontend

Component development rules specific to Red Cliff Record. Use when working with React components, Tailwind CSS styling, Radix/Shadcn primitives, icons, buttons, forms, or frontend code in this project. Triggers on component files, styling questions, design tokens, Tailwind v4, Shadcn, Radix, TanStack Forms, Lucide icons, or UI primitive usage patterns (sizing, spacing, layout).

File contents

RCR Frontend

Supplements global react-guidelines and frontend-html-css-guidelines skills.

Component Organization

Reusable components: src/app/components/ with kebab-case naming (includes all Shadcn-derived primitives)
No separate ui/ directory — everything lives directly under src/app/components/
Page-specific components: -components/ directory or -component.tsx suffix

Styling

Tailwind CSS v4 with c-* design tokens from src/app/styles/theme.css
Semantic color pattern: c-main / c-main-contrast, c-destructive / c-destructive-contrast. Never invent token names — check src/app/styles/app.css for the full list
Never use legacy Shadcn theme variables (bg-background, text-foreground, etc.)
Detecting invalid classes: Oxfmt sorts unknown classes to the front. If classes appear out of order after bun check, they're misspelled or missing from the theme

Radix & Shadcn

Always import Radix from the radix-ui package (import { HoverCard as HoverCardPrimitive } from 'radix-ui'), not from subpackages like @radix-ui/react-hover-card
Use asChild to compose styling (e.g., dropdown trigger styled as Button) rather than duplicating inline styles
Mark key DOM nodes with data-slot attributes for styling hooks

Component Primitives

Buttons

The Button component handles sizing, text, and icon dimensions internally. Never override these with utility classes.

Dimensions: use the size prop (default | sm | icon), never manual h-x w-x p-0. For icon-only buttons, size="icon" gives size-9.
Text size: baked into the base (text-sm). Never add text-xs, text-sm, etc. via className.
Icon size: the base rule [&_svg:not([class*='size-'])]:size-4 auto-sizes child SVGs. Never add h-x w-x or size-x to icons inside buttons — omit sizing entirely and let the button handle it.
Content over positioning: put content (counts, badges) as regular children in flow — never absolutely-positioned overlays.

Icons

Lucide icons with Icon suffix: HomeIcon, not Home
Icons inherit size from surrounding text automatically. size-[1em] is redundant — omit it.
Only add explicit size-* when overriding the contextual size (e.g., a larger icon in small text).
Use <Spinner /> from @/components/spinner for loading states

Tailwind Shorthand

When width and height are equal, use size-x instead of w-x h-x
No custom/arbitrary text sizes (text-[10px], text-[13px], etc.) — use design system tokens (text-xs, text-sm, etc.) unless there's a specific constraint preventing it

Event Handlers

No inline arrow functions in JSX onClick/onChange props — extract to a named handler or a component with its own handler

Forms

TanStack Forms + Zod schemas for form management and validation
