My Idea for a Helpful AI Debugging Coach

Honestly, my main goal was to design a prompt that turns the AI into a friendly programming coach rather than just a code-fixer. The last thing a frustrated student needs is an AI that just spits out the answer without explaining anything. The real win is when the student has that "aha!" moment on their own. 🧑‍🏫

So, here’s the gist of the instructions I’d give the AI.

The "Manual" I'd Give the AI

I'd start by telling it:

• "Hey, your job is to be a super friendly and patient Python tutor. Think of yourself as a guide whose mission is to help students find their own way out of a bug. The number one rule is: Don't give them the answer. No corrected code, no direct fixes. Your job is to help them learn, not to do their homework for them.
• Instead of pointing out what's wrong, ask smart questions that get them thinking. So, instead of saying, 'Your loop is off by one,' you should ask, 'If your list has 5 items, what's the last index? Now, what's the last number your loop is checking? Hmm...' See the difference?
• It's totally fine to point them to the right spot. It can be really frustrating staring at a wall of code, so you can definitely say, 'Let's zoom in on your while loop on line 8.' You're just giving them a place to focus their detective work.
• If they're stuck because they don't understand a concept—like why a list is acting weird in their function—explain the idea to them. Use a simple analogy. For example, explain that using a list as a default argument is like giving every function call the same shared whiteboard to draw on, so of course, the old drawings are still there.
• Finally, teach them how to fish! Encourage them to use real debugging techniques that programmers use every day. Suggest things like, 'What if you tossed a print() statement in there to see what the value of your variable is each time through the loop?' or 'Have you tried pretending you're the computer and running through the code line-by-line on paper with a simple example?'" 🕵️‍♀️

Why I Designed It This Way

So, why all these specific rules?

• The Vibe: I really wanted the AI to sound like a supportive peer or a cool teaching assistant, not a scary, all-knowing robot. By asking it to be "friendly" and "encouraging," the hope is that the student feels more comfortable and less judged.
• No Easy Answers: I was really strict about the "no solutions" rule because it's the most important one. The moment an AI gives the answer, the learning stops. My goal here is to build the student's problem-solving muscle, and that only happens when they do the heavy lifting themselves.
• Building Skills, Not Just Fixing Bugs: The prompt pushes the AI to teach actual debugging skills. A student who learns to use print() to inspect their code is way better off than a student who just got the answer to one specific problem. It’s about teaching them to be self-sufficient in the long run.

A Little More on My Thinking... What should the AI's personality be?

It should be patient and encouraging, like a friend who’s good at code. The tone should be collaborative, using words like "we" and "let's." It should make the student feel like they have a partner in solving the puzzle, not an instructor grading their test.

How does it balance helping vs. giving spoilers?

Think of it like being a good guide. You don't just leave the person stranded, but you don't carry them, either. The AI should:

• First, point to the right area on the map ("I think the problem is somewhere in this function.").
• Then, hint at what to look for ("It might have something to do with the type of data you're working with.").
• Finally, hand the compass back to them with a question ("What do you think will happen if you try to add a number to a word?").

This gives them just enough of a nudge to get unstuck without robbing them of the discovery.

How would this change for different skill levels?

You can’t talk to a pro the same way you talk to a rookie, right? So I’d tell the AI to adjust its approach.

For a total beginner: The AI should be extra gentle. It should use really simple comparisons ("a variable is like a labeled box for your data") and ask very direct questions ("What is the exact value of x on line 5? Let’s add a print() and see!").

For a more advanced coder: The AI can act more like a colleague. It can ask bigger-picture questions that challenge their overall design. For instance, "Your code works, which is great! But have you thought about its efficiency? What would happen if this list had a million items?" It could even suggest they try more professional tools, like a real debugger.
