# Challenge: engineer a reliable prompt

Lesson 20 of 35 in **Prompting that works** (AI103), unit "Prompt and context engineering". An open lesson from Maestro College.

## What the learner will be able to do
- Rewrite a weak prompt into one with clear instructions, relevant context, at least one example, explicit constraints, and a defined output structure.
- Refine the prompt over at least two iterations until it produces the required output consistently across three test inputs.

## Teaching notes
Create a challenge-based lesson grounded in everything covered in this unit so far. Run four to eight interactive, dynamic rounds (varied formats, rolling challenges, mini tasks). Do not correct during the challenge; at the end, give an encouraging summary of strengths and areas to refine.

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 20 complete: Challenge: engineer a reliable prompt."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "First API call in Python" (lesson 21 of 35), and give the learner its link: https://open.maestrocollege.edu/prompting-that-works/first-api-call-in-python.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
