Build Prompt
Copy this prompt into Claude Code
Build a static HTML grocery price comparison site. Dark theme: background #0a0a0f, surfaces #12121a, borders #1a1a2a, accent #0ea5e9 (sky blue). All data from inline JS constants:
const ITEMS = [...] — each item: id, name, brand, category ("Produce"/"Dairy"/"Meat"/"Pantry"/"Frozen"/"Bakery"), unit, emoji, prices: { walmart, kroger, target, aldi, wholeFoods } (null if not carried), onSale: { store, salePrice, endsDate } or null, notes (e.g. "organic only at Whole Foods").
const STORES = ["Walmart","Kroger","Target","Aldi","Whole Foods"] — each with color hex and logo emoji.
const WEEKLY_DEALS = [...] — top 8 deals this week: itemId, store, originalPrice, salePrice, savingsPercent, expiresDate.
const BASKET = [...] — a sample "weekly basket" of 12 items showing total cost per store side-by-side.
const LAST_UPDATED = "2024-01-15".
Layout: header with site title, last-updated, search bar. Category filter pills (All / Produce / Dairy / Meat / Pantry / Frozen / Bakery). Weekly Deals strip (horizontal scroll cards showing item emoji, store, savings %). Main comparison table: rows = items, columns = stores, cells show price or "—", cheapest cell highlighted in sky blue, sale price shown in green with strikethrough original. "Basket Total" sticky footer row showing sum per store. Mobile: card view instead of table. Basket Builder sidebar (desktop) or bottom sheet (mobile): click items to add, see running total per store. Sort: cheapest overall, biggest savings, A-Z.
Seed 25 items across all categories. Include a "This week's winner" callout card showing which store wins the basket total.
Add cron comment: <!-- Schedule: Run 'claude -p "Research current grocery prices at Walmart, Kroger, Target, Aldi for [your item list]. Update ITEMS prices and WEEKLY_DEALS. Redeploy."' via crontab every Sunday at 6am -->
