Find me a lip kit. Search the catalog once, then look up the full product details of the best in-stock result using its product id. Create a cart with one of it, then update that cart to a quantity of 2 and fetch the cart to confirm the total. Choose everything yourself without asking me, and don't start a checkout.
Reasoning
**Searching for Products** I'm currently working on a search operation. My immediate goal is to query the catalog for "lip kit" and then identify the most suitable in-stock item from the results. Following that, I'll retrieve its complete details. **Finding the Right Lip Kit** I'm focusing on procuring a specific "lip kit." My current thought process involves querying the catalog, ensuring I filter for in-stock items, and then selecting the most appropriate variant for the user without further interaction, ultimately adding it to their cart.
