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 apiCommands
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 [qty]
node skills/api/wrapper.js remove
node skills/api/wrapper.js update All commands return JSON from the local API.
Add-to-basket workflow
When the user asks to add an item to the basket:
- First search favourites:
``bash node skills/api/wrapper.js fav-search "USER ITEM" ``
- If there is a clear favourite result that matches the user's intent, add it directly:
``bash node skills/api/wrapper.js add [qty] ``
- If there are multiple plausible favourite results, ask the user which one to add. Include names, prices, and product IDs.
- If there are no good favourite matches, or if the user explicitly asks to look outside favourites, use regular search:
``bash node skills/api/wrapper.js search "USER ITEM" ``
- For regular search results, always confirm with the user before adding anything to the basket.
- After adding, show or summarize the basket:
``bash node skills/api/wrapper.js basket ``
Remove/update workflow
When the user asks to remove or update an item:
- First inspect the basket to get basket item IDs:
``bash node skills/api/wrapper.js basket ``
- Use the basket
item_id, not the product ID:
``bash node skills/api/wrapper.js remove node skills/api/wrapper.js update ``
- If the item to change is ambiguous, ask the user which basket item they mean.
- 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_uidas the product ID foradd. - Use the basket
item_idforremoveandupdate.
