How the output should be structured and presented.
Scenario: Creating a training module on prompt engineering
Role: Instructional designer with 10 years of corporate training experience. Task: Create a 30-minute training module on prompt engineering fundamentals for non-technical employees. Format: Module outline with 5 sections, learning objectives, and a quiz at the end.
RTF stands for Role, Task, and Format — a minimal three-field framework covering the three highest-impact variables in any prompt.
Use RTF when assigning an expert role improves output quality. Use APE when the task is simple enough that a role would add no value.
Yes. RTF works especially well for training and educational content because the Role field sets expert authority and the Format field ensures consistent structure.
