Two minutes on prompting with none of the vocabulary. Bani Chaudhuri compares it to ordering coffee. You do not walk up to the counter and say "drink", you say what size, what milk, how much sugar, and the same specificity is the entire skill here.
The demonstration is two prompts for the same job. "Write an email" gets you something generic. "Write a three sentence email declining a meeting invite, polite but firm, blame a scheduling conflict" gets you something you can send. The pattern behind it is context first, then the format you want, then the tone, and if the first answer misses, say what to change rather than starting over.
