How to write a prompt: why the same model gives completely different answers

1. 1

   One step beyond “make it good”

   When a draft is too long or sounds wrong, “make it better” still leaves the desired change unspecified. Decide what the reader should be able to do after reading it.

   Our goal is for a first-time participant to find the reading group’s time, location and materials. We are not writing an advertisement or a review. A single purpose makes missing details easier to notice.

   A prompt is the request and material you send to the assistant. Treat it as a work brief. An elaborate role description cannot supply a schedule that exists only in your head.

   All event details and sentences here are editorial practice material, not an actual event or reported model test. Try the requests in an available assistant, or write and review them on paper. Matching a sample word for word is not the goal.

1. 2

   Separate source, audience and task

   Start with the notes: 7 November at 2 p.m., second floor of the local library, bring one book. Admission and registration details are unknown. Do not fill those gaps from assumptions about similar groups.

   

   Then name the audience: someone attending this group for the first time. This identifies what the reader does not know more precisely than a broad label such as “beginner.”

   Specify the result: one subject line, three body sentences, the supplied event details and a separate list of items to confirm. Keep only requirements that matter for the intended use.

   The request below separates instructions from source material. That helps inspection but does not guarantee accuracy. Compare the result with the three supplied facts.

   Task: draft a reading-group notice for a first-time attendee.
   Source: 7 November, 2 p.m. / second floor of the local library / bring one book.
   Format: one subject line and three body sentences, calm and friendly.
   Checks: preserve all supplied details. Do not invent admission or registration arrangements. List missing details separately below the notice.

2. 3

   Five fields to check

   Write five headings on paper: situation, goal, material, format and acceptance checks. This is a diagnostic tool for a weak result, not a rule requiring every request to have five paragraphs.

   

   “Use three sentences” sets a format. “Do not invent admission or registration details; list them for confirmation” sets an evidence boundary. Both serve a different purpose.

   Resolve conflicting requirements. If one sentence cannot comfortably preserve all essential details, prioritize the details and relax the sentence limit. Shorter does not automatically mean successful.

   Five fields in this request

   Field	What to supply
   Situation	Notice for a first-time attendee
   Goal	Communicate time, venue and materials
   Material	Only established facts in the practice notes
   Format	One subject line and three sentences
   Checks	Compare with source; separate unknown details

3. 4

   What an example can and cannot supply

   If tone is hard to describe, include one short example: “Bring a book and make yourself comfortable.” Mark it as a style example, and state that factual details must come from the source notes.

   A sample mentioning “the first ten participants” does not establish a ten-person limit for this event. Borrow tone and structure, then check that unrelated sample facts did not migrate into the draft.

   A role such as an experienced editor may guide perspective or organization. It does not confer real credentials or establish facts. Compare results against your criteria rather than assuming a role phrase always helps.

   There is no universally correct number of examples. Begin with one for this small task and add contrasting examples if needed. Check that old dates or instructions do not slip in with them.

4. 5

   Name the change and what must stay

   If only the subject line is too stiff, request a subject-line change and keep the body. Inspect the actual revision rather than accepting a statement that the body was preserved.

   For practice, move the event from the second floor to the first. State that the final venue replaces the old one, while time and materials remain unchanged. Check both the requested change and the untouched facts.

   If revisions become hard to track, gather the final requirements and request a fresh draft. There is no rule that a new conversation is needed after exactly three attempts. In a new chat, supply the required material again.

This is a learning check, not a test you must pass. Use the explanations to understand the ideas.

1. Q1Rewrite “write a good group notice” using the notes. Admission is unknown. Include a format and an evidence check.

   Your writing is not sent anywhere. It disappears when you leave or reload this page, so copy anything you want to keep.

   Read the answer and explanation

   Example: “Write a subject and three-sentence notice for a first-time attendee. Include 7 November at 2 p.m., the library’s second floor and one book. Do not invent an admission price; list it for confirmation.” These are invented practice details. The request specifies both form and an evidence boundary.

2. Q2The draft has three sentences but omits the venue. Correct the claim that the sentence count makes it successful.

   Your writing is not sent anywhere. It disappears when you leave or reload this page, so copy anything you want to keep.

   Read the answer and explanation

   The venue is an essential requirement, so the draft is not ready. Request its inclusion while preserving other facts, then compare against the notes. Relax the length requirement if it obstructs essential information.

3. Q3For practice, the venue changes from the second floor to the first. Write one revision request and two checks.

   Read the answer and explanation

   Request: “Change only the venue to the library’s first floor; preserve date, time and materials. The first floor is final.” Check that the old floor is gone and the other details remain correct. The floor change is an invented exercise condition.

   Try it: make a pre-publication checklist

   Beside the final draft, list time, venue, materials, missing facts and reader suitability. Mark each checked, needs revision or not yet confirmed. Do not mark something checked merely because the text looks complete.

   Admission and registration remain unknown in our practice material. If publication requires them, someone must obtain the real details. Sending or publishing is a separate action; this lesson stops at drafting and review.

   Finish with one sentence: “Who will read what, based on which material, in which form?” Being able to answer it means the task is clearer. The next lesson examines errors that still slip into a fluent response.
