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

1. Identify the last code I worked with (wrote, edited, or accepted from AI)
2. 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?
3. Present questions one at a time
4. Wait for my answer before revealing the correct response
5. 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?"
• "What would break if input Z was provided?"

Level 4: Analysis

• "What are the performance implications of this approach?"
• "What edge cases might cause issues?"
• "How does this compare to alternative X?"

Level 5: Synthesis

• "How would you refactor this for better testability?"
• "What would need to change to support X?"
• "Design an extension that adds Y"

Focus areas

When focus is specified (e.g., /learn:quiz error handling), prioritize questions about:

Focus	Question Themes
error handling	Try/catch, error types, recovery strategies
performance	Big-O, optimization, bottlenecks
security	Input validation, XSS, injection
testing	Test cases, edge cases, mocking
architecture	Patterns, separation of concerns, SOLID
types	TypeScript types, inference, generics

Difficulty modes

Default

• 3 questions
• Mix of Level 1-3
• Focus on understanding current code

--hard

• 5 questions
• Levels 3-5
• Include hypothetical modifications
• Ask about trade-offs and alternatives

• Suggested practice: [Specific exercise]

Example session

User: /learn:quiz

Claude: Looking at your last code - the useEffect hook for data fetching.

## Question 1 of 3

In your useEffect, you have an empty dependency array [].
What does this mean for when the effect runs?

User: It runs only once when the component mounts

Claude: ### Feedback
Correct! An empty dependency array means the effect runs only on mount
(and cleanup on unmount).

**Key insight**: The dependency array controls WHEN effects re-run.

**Related concept**: What happens with no array vs. [someValue]?

Tips for users

1. Be honest: Wrong answers are learning opportunities
2. Explain your reasoning: Helps identify gaps even in correct answers
3. Ask follow-ups: If feedback is unclear, dig deeper
4. Track weak areas: Note topics that need more practice
