Vague vs Clear Prompts

A vague prompt makes the AI guess what you mean. A specific prompt pins it down — and the more specific you are, the more useful the answer.

By the end of this lesson you can:

  • Spot what is missing from a vague prompt.
  • Rewrite a vague prompt into a specific one.
  • Explain why specific prompts get better answers.

Warm-Up · "Make It Better"

8 min

Last lesson we learned the R-T-D-F recipe. Now we focus on being specific.

Imagine you tell a helper just two words: "make it better." Better how? Could they possibly do a good job?

Reveal the thinking

No — too vague. They'd have to guess. A specific request like "make this poster title shorter and add a fun emoji" is something they can actually do well.

03

New Concept · Pin It Down

18 min

A vague prompt leaves out the things the AI needs. A specific prompt names them. Ask yourself four quick questions:

  • Who is it for?
  • What exactly do I want?
  • How much — how long, how many?
  • What shape — a list, steps, a paragraph?

See the difference. First, vague:

You

tell me about Malaysia

🤖 AI

Malaysia is a country in Southeast Asia with lots of culture, food and nature. What would you like to know more about?

Now, specific:

You

List 5 interesting facts about Malaysia's rainforests, for a 10-year-old, as short bullet points.

🤖 AI

• Malaysian rainforests are over 130 million years old. • They are home to the rare Rafflesia, the world's biggest flower. • Orang-utans and tapirs live in them. • The trees can grow taller than a 20-storey building. • They make rain and clean the air for everyone.

The golden rule

More specific in, more useful out. Specifics are not extra work — they are how you get exactly what you need.

Worked Example · The Specificity Ladder

18 min

Watch one request climb the ladder, getting more specific each step.

  • Rung 1 (vague): "help with my essay"
  • Rung 2: "help me plan an essay about recycling"
  • Rung 3: "give me a 4-point plan for an essay about recycling, for a 10-year-old"
  • Rung 4 (specific): "You are a writing coach. Give me a 4-point essay plan about why our school should recycle, for a 10-year-old, as a numbered list with one example each."
You

You are a writing coach. Give me a 4-point essay plan about why our school should recycle, for a 10-year-old, as a numbered list with one example each.

🤖 AI

1. It saves resources — e.g. recycling paper means fewer trees cut down. 2. It cuts waste — e.g. less rubbish going to the landfill near town. 3. It saves money — e.g. the school spends less on bins and bags. 4. It sets an example — e.g. younger students copy good habits.

The takeaway

Each rung removed a guess. By the top, the AI knew exactly what to make — and it did.

Try It Yourself

20 min

Use the teacher-opened chatbot.

01 🟢 What's missing?

For each vague prompt, write what's missing (who / what / how much / shape): "tell me about animals", "help me revise", "give ideas".

Hint

Each is missing several. Pick the most important one to add first.

02 🟡 Sharpen it

Take "help me revise" and rewrite it into a specific prompt for a real subject you're studying. Test both and compare.

Hint

Add the subject, the topic, how many questions, and "give feedback".

06

Mini-Challenge · Climb the Ladder

12 min

Start with a vague prompt of your own. Then write three rewrites, each more specific than the last, until the top rung is razor-sharp.

It works if each rung adds a real detail and the final prompt leaves the AI nothing to guess.

Show one ladder

1. "draw something cool" → 2. "describe a cool robot" → 3. "describe a friendly robot for a story" → 4. "Describe a friendly cleaning robot for a 9-year-old's story, in 4 sentences, that loves durian."

07

Recap

5 min

Vague prompts make the AI guess; specific prompts tell it who, what, how much and what shape. Climb the specificity ladder and the answers get sharper at every rung.

Vocabulary Card

vague
Unclear or missing details, so the AI must guess.
specific
Clear and detailed — who, what, how much, what shape.
constraint
A limit you set, like "in 3 sentences" or "nothing scary".

Homework · Sharpen Two Prompts

≤ 20 min

Write two vague prompts, then rewrite each into a specific one. Under each, note the details you added.
