remove_from_cart
Update local cart tracking after removing items from your Kroger cart. This tool syncs local data when you've already removed products through the Kroger app or website.
Instructions
Remove an item from the local cart tracking only.
IMPORTANT: This tool CANNOT remove items from the actual Kroger cart in the app/website.
It only updates our local tracking to stay in sync. The user must remove the item from
their actual cart through the Kroger app or website themselves.
Use this tool only when:
1. The user has already removed an item from their Kroger cart through the app/website
2. You need to update the local tracking to reflect that change
Args:
product_id: The product ID to remove
modality: Specific modality to remove (if None, removes all instances)
Returns:
Dictionary confirming the removal from local tracking

Implementation Reference
- The main execution logic for the 'remove_from_cart' tool. Removes specified product from local JSON cart tracking file. Uses list comprehensions to filter out matching items. Updates timestamp if changes made. Includes input validation via type hints and comprehensive error handling.
