New Grok Bot template drops as a full-stack shopping agent with actual price verification logic.

Core architecture:
- Total cost calculation engine: aggregates item price + shipping + tax + fees, flags incomplete data instead of estimating
- Live coupon validation: tests promo codes in real-time, only surfaces confirmed working codes with source attribution and delta calculations
- Multi-dimensional comparison matrix: generates feature grids across 10+ products (price, shipping speed, ratings, warranty) with structured product cards
- Scam filter layer: pattern matching to exclude obvious fake listings (e.g., "$19 2TB drives") and unverified merchants
- Local merchant integration: phone-based API to query brick-and-mortar inventory + pricing, injects results into same comparison pipeline
- Async price monitoring: background workers track sales, price drops, restocks with threshold-based notifications
- Human-in-the-loop checkout: requires explicit user confirmation before any transaction

Technical win: This isn't just web scraping + LLM summarization. The coupon validation and local merchant calling are the killer features - most shopping agents hallucinate discounts or skip non-digital retailers entirely.

Practical use: Template-based deployment means you can clone the entire agent setup. No rate limits mentioned, but Grok's real-time web access + phone call capability makes this more powerful than static price comparison tools.

Shipped as a reusable template for Grok Bot users.
