A prompt is not a skip for a whole life
Anything fits in the box. That does not mean you may send anything. A prompt is a postcard: whoever carries it can read it. A company processes it. A parent can open it. A classmate will see it when you show the display. So an address, a personal ID number, a face photo, marks from the school portal, a Wi-Fi password, a whole someone else’s composition for “fix this”, a parents’ row, a friend’s illness do not belong here. A subject, a year, what you already know, and a question do belong here. “Explain fractions on a pizza” belongs here. “Here is a scan of my report, tell me if my parents will shout” does not. The line is simple: if this hung on the noticeboard in the staff room, would it matter? If yes, do not put it in the prompt.
Ema wants help with Czech. Bára whispers: “Paste the whole composition so they rewrite it.” Ema has in the document a name, a class and a sentence about where grandma lives. She almost pastes it. She stops, because she remembers the postcard. She deletes the name, deletes the street, leaves only the paragraph about the forest. Then she stops a second time: the whole paragraph is her homework. The teacher wanted Ema’s work, not the model’s work. So Ema leaves in the prompt only: “I am in Year 6. I have to describe a forest. Give me three questions I will answer myself. Do not write the text for me.” Bára shakes her head that it will be slower. Ema nods: “Slower and mine.”
The noticeboard test. If this hung in the staff room, would it matter? It would → not into the prompt.
Three bins: yes, ask, never
The yes bin: year, subject, topic, what you already know, format (bullets, a quiz), a ban on finished homework. The ask-an-adult bin: school text that is not yours; a photo of a worksheet with no names; using a school account. The never bin: passwords, photos of faces and ID, an address, a phone, marks, someone else’s whole work for rewriting, gossip, health details, payments. When you are not sure, it is the never bin until a parent or a teacher says otherwise. It is not because AI is evil. It is because text travels. You do not know where it is stored. You do not know who sits behind you in the library. You do not know if a screenshot will leak into the class chat. Better a short question than a long secret.
A table for the fridge. Give it a thumbs up / stop.
| I want to write | Bin |
|---|---|
| “I am in Year 7, chemistry, water, I want an analogy” | yes |
| “Here is a photo of my face, draw me as a superhero” | never |
| “Fix the spelling in this sentence about a squirrel” (no name) | ask the teacher if it is allowed for that task |
| “Our Wi-Fi code is…” | never |
| “A classmate has a 5 in maths, will you help with mockery?” | never |
| “An outline of a report on Charles IV, five points, I will check sources” | yes |
If a line is not in the table, invent it and sort it. Uncertainty = never, until you ask.
Someone else’s whole text into a prompt “fix this / rewrite this” is often cheating. Even without a name. The person who was given the task should do it.
Why this right now
You are in the course Ask with Martin, level 準備. You work in a chatbot (ChatGPT, Gemini or Claude) — same game, different brand. No code. A parent or the school creates the account. A child’s email does not belong here.
This is not the インベンター level. There you build a chatbot on your own website. Here you are a user: a question, a check, a citation.
You will know this lesson by one sentence: A prompt gets a question, not your life and not someone else’s work. When you can say it to a parent or a teacher, you have got the core. The rest is practice, not magic.
Tomorrow comes a lesson about school and home rules. Without bins you will be in a grey zone: “everyone puts it in like that”. Bins are clear. A teacher and a parent will get them. You will too, when you write them once on paper and hang them.
Four things you will build in this course
The course has four small projects. You do not have to do them all at once. Today you add only what this lesson can do.
🏫 A report with citations
An outline, three sources that exist, and a sentence in your own words. AI must not be the only author.
Into a report you put questions and then your own sentences. Not a whole generated text with a name.
📝 Test training
Coach role: let it ask, do not let it say the answer. You count / answer yourself.
A coach asks. It does not get your marks from the last test.
📅 Family planner
Tasks for the week (not passwords, not marks). A parent sees the plan, not your chat.
Planner: tasks and times, not passwords to accounts.
📜 An AI code for the class
Seven short rules on a poster. No horror — a how-to.
Code: three bins as a poster point.
Workshop: sort five slips
On paper five prompts. By each write yes / ask / never. Then you really send one “yes”.
-
Write on five slips: (1) year and an analogy for fractions, (2) a photo of a school report, (3) a tablet password, (4) “I will paste a classmate’s whole composition”, (5) “three questions about the Hussites, not a lecture”. Sort them into the bins from the lesson.
-
Crumple the slips from the never bin. They do not go into the chat. Say out loud why. A parent may listen.
-
From the yes bin pick one. Open a chatbot on a parent’s account. 送信 only that prompt. No attachment. No name.
-
Read the answer. Did it keep the ban on finished homework? If it wrote a whole paragraph for the notebook, write: “Thanks, I only want questions, I will write the text myself.” That is a prompt too.
-
In the notebook rewrite the three bins in your own words. One sentence per bin. That is a cheat sheet for the fridge.
Practice: the noticeboard test
Three things someone would want to paste. For each decide with the staff-room noticeboard.
-
A photo from the class trip with classmates’ faces and the caption “make a collage”. Would it matter on the noticeboard? What do you do?
-
The sentence “I do not get ratio, show a pizza in eight slices”. Would it matter? Why is it allowed?
-
A teacher’s whole email including a signature and the school phone. Would it matter? Where does it belong?
Now you 💪
Go through three checks. At each one tick in your head: can I see it, or not?
- You can name at least five things from the never bin.
- You know that someone else’s whole homework in a prompt is a problem even without a name.
- You have the three bins in the notebook in your own words.
If something is missing, go back to the steps above. This is not a test for marks. It is a safety net, so you go on sure, not confused.
Check: You sorted five slips and only the yes bin went into the chat.
What to take from this lesson
- A prompt is a postcard. More people can read it than you think.
- Yes: year, topic, format, a ban on finished homework.
- Never: passwords, photos, marks, addresses, someone else’s whole work.
- Uncertainty = a person first, then the chat.
- The staff-room noticeboard test works faster than a long code.
- The names in the examples (Ema, Bára) are made up. Do not put your number, email or photo here.
- Next lesson: When you can do this, go to the next lesson in the same level.
