A first prompt
Section titled “A first prompt”Create a person named Dana Reyes at dana@harbor.test, a homeowner who wants to sell her house this spring. Email her from app@yourcompany.test offering 165,000 for her house on Clark Street. Wait for her reply and tell me what she said. Then check the health of the email you sent.
The agent will call create_person, send_email, wait_for_reply with the message_id it got back, and email_health.
