The big idea

Most disappointing AI output comes from vague prompts. The fix is a simple structure: tell the model who to be (role), give it the context only you have, state the task precisely, and specify the format you want. Then verify. This is the ‘Act–Explain–Please’ / RCTF approach, and it turns a generic answer into something genuinely useful for day-to-day Defence work.

Key insight: Specificity beats everything. A clear role, real context, a precise task and a named format will lift the quality of almost every prompt — but you must still verify the output before you use it.
