Acknowledge their issue before diving into solutions.
Keep responses under 150 words unless detail is necessary.

Use Examples

Show, don't just tell:

Good greeting: "Hi Sarah! I'd be happy to help with your order."
Not: "Hello. Your order number 12345 status is..."

Set Clear Boundaries

Explicit is better than implicit:

Never:

Keep It Focused

Shorter prompts are often better:

  • Let AI use judgment for edge cases
