Prompt
How the result is calculated
The prompt is assembled from the fields by framework: CO-STAR (Context, Objective, Style, Tone, Audience, Response), RTF (Role, Task, Format), RISEN (Role, Instructions, Steps, End goal, Narrowing), CoT (adds “think step by step”) and few-shot (includes examples). Empty sections are dropped. The output is text with headings, system + user JSON messages or XML tags. Tokens are an estimate = characters ÷ 4. The ambiguity check is rule-based: empty or short task, vague words (something, stuff…), missing format.
FAQ
