Grocery API Skill

Use this skill when the user asks about Sainsbury's groceries, favourites, searching products, adding/updating/removing basket items, or viewing the basket.

The local API must already be running on port 7876:

GROC_API_PORT=7876 npm run api

Commands

Run from the repo root:

node skills/api/wrapper.js fav-search "milk"
node skills/api/wrapper.js search "milk"
node skills/api/wrapper.js favourites
node skills/api/wrapper.js basket
node skills/api/wrapper.js add <product-id> [qty]
node skills/api/wrapper.js remove <item-id>
node skills/api/wrapper.js update <item-id> <qty>

All commands return JSON from the local API.

Add-to-basket workflow

When the user asks to add an item to the basket:

1. First search favourites:

   node skills/api/wrapper.js fav-search "USER ITEM"
   

2. If there is a clear favourite result that matches the user's intent, add it directly:

   node skills/api/wrapper.js add <product-id> [qty]
   

3. If there are multiple plausible favourite results, ask the user which one to add. Include names, prices, and product IDs.

4. If there are no good favourite matches, or if the user explicitly asks to look outside favourites, use regular search:

   node skills/api/wrapper.js search "USER ITEM"
   

5. For regular search results, always confirm with the user before adding anything to the basket.

6. After adding, show or summarize the basket:

   node skills/api/wrapper.js basket
   

Remove/update workflow

When the user asks to remove or update an item:

1. First inspect the basket to get basket item IDs:

   node skills/api/wrapper.js basket
   

2. Use the basket item_id, not the product ID:

   node skills/api/wrapper.js remove <item-id>
   node skills/api/wrapper.js update <item-id> <qty>
   

3. If the item to change is ambiguous, ask the user which basket item they mean.

4. After removing or updating, show or summarize the basket.

Notes

• Prefer favourites over regular search for add requests.
• Do not add ambiguous items without asking.
• Do not use regular search additions without confirmation.
• Use the product_uid as the product ID for add.
• Use the basket item_id for remove and update.
