Module 5: How to write great prompts (without feeling silly)

A prompt is just what you type (or say) to the AI. You do not need special 'AI language'. The trick is to be clear, give a little context, and ask for the format you want.

A gentle truth
If you can order coffee and explain how you like it, you can write prompts. AI is basically a cafe where the menu is infinite and sometimes the barista improvises.

5.1 The Prompt Sandwich (a simple method)

Here is a method that works for almost everything. Think of it as a sandwich:

  1. Top slice: the job (what you want).
  2. Middle: the important details (context, facts, constraints).
  3. Bottom slice: the output format (how you want it delivered).
Prompt Sandwich template
JOB: [What you want the AI to do]
DETAILS: [Key facts, who it is for, what to include/avoid]
FORMAT: [Dot points / email / table / checklist / script]
TONE (optional): [Friendly / formal / simple / calm]

5.2 Example: from vague to useful

Vague prompt:

Vague prompt
Help me write an email.

Better prompt (Prompt Sandwich):

Better prompt
JOB: Write an email.
DETAILS: It is to my dentist. I need to reschedule my appointment because I have a family issue. I want to ask for the next available time.
FORMAT: Short email under 120 words with a subject line.
TONE: Polite and simple.

Best prompt (adds a helpful constraint):

Best prompt
JOB: Write an email.
DETAILS: It is to my dentist. I need to reschedule my appointment because I have a family issue. Do not mention details. Ask for the next available time.
FORMAT: Short email under 120 words with a subject line. End with 'Kind regards, [NAME]'.
TONE: Polite and simple.

5.3 The 5 ingredients of a strong prompt

If you ever feel stuck, add one of these:

5.4 The best follow-up prompts (copy/paste)

Most people get the best result on the second or third message. Here are useful follow-ups you can reuse:

5.5 Getting the AI to ask you questions first

This is one of the most powerful tricks for beginners. It stops the AI from guessing.

Clarifying-questions prompt
Before you answer, ask me up to 5 questions to make sure you understand what I want. Ask them one at a time and wait for my reply.

5.6 Getting more reliable answers (reduce hallucinations)

AI can sometimes invent details. You can reduce that risk by telling it how to behave.

Anti-guessing prompt
If you are not sure, say so. Do not guess. If you make any assumptions, list them. Then suggest how I can verify the key facts.

5.7 Asking for a specific output style

A lot of frustration comes from answers that are the wrong shape. You can fix that by asking for format up front.

Format prompt example
Explain this in a 2-column table: left side 'In plain English', right side 'What I should do next'.

5.8 Prompting for numbers (carefully)

AI can do basic maths, but it can also make mistakes. If you need accurate numbers:

  1. Provide the numbers clearly.
  2. Ask it to show the calculation steps.
  3. Check the result yourself (or ask it to re-check).
Numbers prompt example
Here are my weekly expenses: groceries $180, petrol $60, phone $25, power $45.
1) Add them up.
2) Show your working.
3) Then suggest one place I could reduce costs by $10 without being unrealistic.

5.9 Practice lab (10 short exercises)

Do these one at a time. They build skill quickly.

  1. Write a polite text message to confirm an appointment time.
  2. Rewrite a paragraph to be clearer and shorter.
  3. Turn a messy list of tasks into a checklist.
  4. Explain a confusing term in simple language with an example.
  5. Ask the AI to ask you clarifying questions before answering.
  6. Get 3 alternative versions of the same email (friendly, neutral, formal).
  7. Ask for a plan with steps and a timeline.
  8. Ask for pros and cons of a decision you are considering.
  9. Ask for a script to call a company and ask for help.
  10. Ask the AI to verify itself: assumptions + what to double-check.
