Quiz me
Test understanding of recently written or accepted code.
Usage
/learn:quiz # Quiz on last code worked with
/learn:quiz error handling # Focus on specific aspect
/learn:quiz --hard # More challenging questions
Instructions
- Identify the last code I worked with (wrote, edited, or accepted from AI)
- Generate 3-5 questions that test understanding at different levels:
- Recall: What does this code do?
- Understanding: Why was this approach chosen?
- Application: What would happen if X changed?
- Analysis: What are the trade-offs of this approach?
- Synthesis: How would you extend this?
- Present questions one at a time
- Wait for my answer before revealing the correct response
- Provide explanations with each answer, not just "correct/incorrect"
Question types
Level 1: Recall
- "What does the function X return?"
- "What parameters does Y accept?"
- "What happens when Z is called?"
Level 2: Understanding
- "Why do we use X instead of Y here?"
- "What problem does this pattern solve?"
- "Why is this line necessary?"
Level 3: Application
- "What would happen if we removed line X?"
- "How would you add feature Y to this code?"
