## Curator’s note
The useful output is an understandable comparison that includes the assumptions behind it.

## Before you try it
Provide the items and constraints, and ask the agent to verify details at the source.

## Suggested approach
1. Choose a small shopping list.
2. Ask for a comparison including delivery and availability.
3. Review the result before making a purchase.

## Suggested prompt
Compare these shopping options, including delivery and availability. Link each source and flag prices that need rechecking.
