**What this tool does:** Takes the items collected in working memory, derives totals, creates the `orders` and `order_items` records, and returns a confirmation message, letting the agent wrap up an order as soon as the customer shares an address. |
**Working memory integration:** This tool demonstrates how VoltAgent's working memory maintains conversation context across messages - the AI agent remembers cart items and delivery details without requiring the customer to repeat information. |
## Check Order Status Tool |
