Problem Solving & Design 90
The implementation fits the brief precisely and delivers a polished, visually differentiated single-page experience with strong responsive layout and clear usability cues throughout.
- +Per-category CSS custom property tone system (`tone-whites`, `tone-darks`, etc.) gives each card a distinct visual identity without redundant class sprawl
- +Responsive grid adapts from single column to `md:grid-cols-2` and `xl:grid-cols-3` for category cards; header stacks on mobile and rows on `lg:`
- +Progress bar in each `CategoryCard` gives immediate visual feedback on how close a load is to ready
- +`sr-only` labels on form inputs and `aria-label` on remove buttons cover accessibility basics
- +Sticky header keeps total and Clear Done in view at all scroll positions
- -No visual transition or confirmation when 'Clear Done' removes groups — items disappear abruptly despite `TransitionGroup` being present on item lists
- -'Remove' button is `opacity-0` on non-hover on desktop (only visible on hover/group-hover), which may cause discoverability issues for keyboard and touch users
Completeness 92
All five brief-specified features are present and wired end-to-end: add items by name+category, grouped category cards with item counts, ready indicator at ≥3 items, per-item removal, Clear Done button, and a header total/ready count.
- +All five wash categories (whites, lights, darks, delicates, heavy-duty) defined in `categories.ts` and rendered via `CategoryCard` in `app.vue`
- +`clearReady()` in `useLaundry.ts` removes all categories meeting the `READY_THRESHOLD=3` threshold in one operation
- +Header displays both total item count and ready load count with `aria-live='polite'` for accessibility
- +localStorage persistence implemented with SSR-safe guard (`import.meta.client`) and try/catch around read and write
- +Empty-state card shown when `totalItems === 0`, and per-card empty state when category has no items
- -Brief says items are displayed in 'grouped lists by category' — all five category cards are always shown even when empty, which slightly departs from the 'grouped lists' framing but is functionally acceptable
- -No validation feedback shown to the user when the name field is empty beyond the button being disabled
Technical Craft 87
Clean Nuxt 4 + Vue 3 Composition API implementation with well-separated composable, typed interfaces, SSR-safe localStorage, and polished CSS custom property theming — a notch above average for this scope.
- +`useLaundry.ts` is a self-contained composable with clear single-responsibility functions; state is module-level ref shared across calls
- +`CategoryId` union type and typed `Category`/`LaundryItem` interfaces in `categories.ts` enforce correctness at the component boundary
- +`crypto.randomUUID()` used for IDs — no timestamp or Math.random collision risk
- +localStorage read wrapped in try/catch with SSR guard; write also try/catch'd — robust against quota errors and server-side rendering
- +`READY_THRESHOLD` constant is a single source of truth referenced in both composable and UI copy
- -No tests of any kind (unit or e2e) present in the repo
- -`useLaundry` module-level `items` ref is shared across all composable instances — fine for SPA but could cause cross-request state leaks in SSR mode if not carefully guarded
- -README is the default Nuxt starter template with no project-specific documentation
