mcd-saver-checkup: McDonald’s Price-Difference Auditing Skill

**What it is**: mcd-saver-checkup is a price-difference auditing Skill for McDonald’s China MCP. The project describes it as a “McDonald’s savings checkup.” Rather than first asking what you want to eat, it checks for possible price differences among existing ways to order. **What it does**: The Skill enumerates all ways to order and recalculates each one by calling calculate-price, reporting the differences between options, what accounts for those differences, and the threshold for adding items to an order. **Highlights**: The project emphasizes showing price differences through item-by-item recalculation rather than giving only a single savings conclusion. The repository uses HTML, is licensed under MIT, and the GitHub page shows 206 stars.
