How to talk to an AI: Role, Task, Context, Format
The R-T-C-F prompt structure
Use one repeatable structure for everyday work:
- Role: Who should the AI act as?
- Task: What should it produce?
- Context: What background does it need?
- Format: What shape should the output take?
Example prompt
You are an experienced geriatrician working in a small Indian nursing home. Draft a one-page handout for families of residents newly diagnosed with mild dementia. Use simple English with Hindi terms where helpful. Use four short sections: what it is, what to expect, what families can do at home, and when to call us.
Practice exercise
Pick one repeated task from your facility. Write one R-T-C-F prompt. Run it in both Claude and ChatGPT, compare the tone and structure, then decide what you would edit before using it.
