M-005One-Shot Email Categorizer
Description
Nebula Corp's support inbox is overflowing. They need an automated triage system that categorizes incoming emails into Billing, Technical, or General using a one-shot prompt. The current function doesn't use any examples and the model keeps returning inconsistent labels. Build a prompt constructor that uses exactly one well-chosen example to teach the model the expected format, and handles any email topic.
