"Prompt engineering" sounds technical, but for everyday use it mostly means one thing: giving an AI assistant the same clear brief you'd give a capable new colleague. You don't need secret phrases or special syntax. This guide gives you a simple checklist, examples you can copy, and the mistakes to avoid.
Why Vague Prompts Get Vague Answers
AI assistants know a lot about the world in general and nothing about your situation unless you tell them. Ask for "an email about the meeting" and you'll get something generic, because the assistant doesn't know who it's for, what the meeting is, or what tone you want.
The second prompt takes 20 seconds longer to write and saves several rounds of back-and-forth.
The CRAFT Checklist
Use these five parts as a checklist. Simple requests won't need all of them; important ones usually do.
| Letter | Part | Ask yourself | Example |
|---|---|---|---|
| C | Context | What background does it need? | "I run a small bakery in Leeds…" |
| R | Role | Who should it act as? | "Act as an experienced copywriter" |
| A | Action | What exactly should it do? | "Write three Instagram captions" |
| F | Format | What shape should the answer take? | "Each under 25 words, with one emoji" |
| T | Tone | How should it sound? | "Warm and playful, not salesy" |
Six Habits That Improve Any Prompt
- Give an example. Paste something in the style you want: "Write it like this one."
- Name the audience. "Explain inflation to 15-year-olds using the price of trainers" beats "explain inflation".
- Provide the material. To summarise or answer questions about a document, paste or upload it, then say "answer only from the document above". This sharply reduces made-up details.
- Break big tasks into steps. Outline first, then each section, reviewing as you go.
- Ask it to ask you questions. For complex tasks: "Before you start, ask me anything you need to know to do this well."
- Iterate. Treat the first answer as a draft: "shorter", "more formal", "the second point is wrong: our return window is 60 days".
Copy-and-Paste Prompt Patterns
| Goal | Try this |
|---|---|
| Understand something | "Explain [topic] as if I'm a beginner. Then give an analogy and a real example." |
| Summarise | "Summarise this in 5 bullet points for a busy manager. Put the decision needed first." |
| Improve your writing | "Edit this for clarity. Keep my voice. List the changes you made." |
| Brainstorm | "Give me 10 ideas for [goal]: some safe, some bold." |
| Decide | "List pros and cons of [A] vs [B] for [situation], then recommend one and explain why." |
| Learn | "Quiz me on [topic], one question at a time. Wait for my answer and explain mistakes." |
| Stress-test | "What are the weaknesses in this plan? What would a sceptic say?" |
Common Mistakes
| Mistake | What happens | Fix |
|---|---|---|
| Too vague | Generic, bland output | Add context, audience and format |
| Everything in one prompt | Muddled results | Break it into steps |
| Accepting the first answer | Missed improvements | Iterate with specific feedback |
| Not giving source material | Made-up facts | Paste or upload the document |
| One long chat for many topics | The AI mixes things up | Start a new chat per topic |
| Asking "isn't this great?" | The AI tends to agree | Ask for weaknesses instead |
| Pasting sensitive data | Privacy risk | Anonymise, and use approved work tools |
Key Takeaways
- Good prompting is clear communication: context, role, action, format and tone (CRAFT).
- Examples, a named audience and source material make the biggest difference.
- Iterate: the first answer is a draft.
- Ask for weaknesses, not agreement, and verify anything important.
