RCAF Prompt Structure — AI Glossary

RCAF is a 4-part prompt skeleton — Role, Context, Action, Format — for drafting maintainable AI prompts. Role assigns the model an identity, Context supplies background the model needs, Action states the task, and Format specifies the output shape. RCAF is deliberately minimal (4 slots) compared to alternatives like RACE, CREATE, RISEN, or TCREI, which use 5-7 slots and are harder to remember under pressure.
