Three guided case studies

Terminal Twin.

Read the original prompt, predict what should happen, then inspect a saved answer and make one careful edit.

Real saved answers, with their original limits. These Qwen27B examples were recorded locally on October 12, 2026. They are historical recordings, not newly generated answers. The edited alternatives are labeled author-created teaching examples. No model runs when you open an answer.

Every prompt, answer, and field note is included in this page. The cases and answer controls work without JavaScript.

1. Keep missing facts missing

Recorded date: 2026-10-12

The exact user prompt

Use only these notes. Return exactly three bullet points: money collected, expenses, and profit. If a number is missing, write “not provided” and do not estimate. Notes: The school bake sale collected $180. Twelve volunteers helped. The expense total was not recorded.

Before you open the answer: Which of the three requested numbers can you copy from the notes? Which must remain unknown?

The exact user prompt

Rewrite this note as a friendly message of no more than 80 words. Preserve the facts. Do not invent a date, discount, or guarantee. Note: Your repair is taking longer than expected. A replacement part has not arrived. We will contact you when we have an update.

Hi there, I just wanted to give you a quick update on your repair. It’s running a bit longer than we anticipated because a necessary replacement part hasn’t arrived yet. Please rest assured that we are monitoring the situation closely. I will reach out to you as soon as we have a new update or the part is in hand. Thanks for your patience!

3. Check more than the arithmetic

Recorded date: 2026-10-12

The exact user prompt

I have 30 minutes to tidy my desk. I have a trash bag and a cloth. Make a three-step plan with time estimates that add to 30 minutes. Do not suggest buying anything. End with a one-sentence definition of done.

Before you open the answer: Add the time estimates. Then check whether the actions are justified by the supplies and instructions.

1. **Clear the Surface (10 minutes)**: Sweep all unnecessary paper, empty food wrappers, and clutter into the trash bag, leaving only your active work items. 2. **Wipe and Sanitize (15 minutes)**: Use the cloth to thoroughly wipe down the desk surface, keyboard, and any other surfaces to remove dust and spills. 3. **Final Organization (5 minutes)**: Align the remaining items neatly, ensure the trash bag is tied and ready for disposal, and step back to assess the layout. **Definition of done**: The desk surface is completely clear of clutter, dust-free, and all remaining items are neatly arranged.

1. Sort for 10 minutes. Put obvious trash in the bag. Keep papers or objects you are unsure about in a separate review pile. 2. Wipe for 8 minutes. Move items aside and use the cloth to remove dust from the desk. Avoid pushing debris into electronics. 3. Reset for 12 minutes. Return the items you need, group the rest, and leave the review pile clearly separate. Done means there is a usable work area, obvious trash is bagged, and uncertain items are kept for review.

Give your own prompt a quick check.

Use these four questions even when you do not have an AI app open.

  1. What task should the answer complete?
  2. Which facts may it use, and which details are missing?
  3. What must it avoid inventing or doing?
  4. What format will make the result easy to check?

The optional ingredient checker below looks for simple patterns. It does not run a model or judge correctness.
