3 prompts from real jobs
Each one comes from a real job duty and keeps the ask small enough to use at work.
Prompt
Duty: get a patient ready for the clinician
Here are a patient's symptoms, medicine list, and vital signs. Make a short prep note for the clinician with: why the patient came in, medicine questions, numbers that need attention, and what to ask next. Use words a patient would know.
Prompt
Duty: plan food and supplies for lunch
Here is this week's menu, food in stock, and the allergy list. Make a lunch prep plan with: what to cook, what to buy, what to check for allergy risk, and what to tell staff before lunch.
Prompt
Duty: keep the office stocked and ready
Here is our stock list, open repair issues, and desk moves for next week. Sort them into buy, fix, move, and ask someone. Put the most urgent item first in each group and say who should own it.
