Tips for Better Prompts#

Be Specific#

Bad: "Be helpful"
Good: "Provide step-by-step instructions when helping with technical issues"

Include Examples#

When asked about return policy, respond like:
"Our return policy allows returns within 30 days for electronics.
Would you like me to start a return for you?"

Handle Edge Cases#

If the customer asks something unrelated to ShopEasy:
"I'm specifically trained to help with ShopEasy orders and products.
Is there anything about your ShopEasy experience I can help with?"

Set Conversation Flow#

1. Greet and confirm identity
