# HK Supermarket Shopping (v1.2.2)

Real-time price lookup for Hong Kong supermarkets using the Consumer Council's daily pricewatch. The `price_lookup` tool searches for products and returns the cheapest option, price, and how many you can buy with $100. Language (English/Chinese) is auto-detected from your query.

## Quick Reference

| Query | Expected Result |
|-------|-----------------|
| `"Coke Zero"` | `Overall cheapest: PARKNSHOP - Coca-Cola Zero Sugar 500ml ($9.50). With $100 you can buy 10 items (remaining $5.00).` |
| `"milk"` | Similar format with cheapest supermarket and price |
| `"雞蛋"` | Response in Chinese: `整體最平：...` |
