Code Debugging Helper
An AI prompt that helps you find and fix bugs by explaining the cause, not just handing you a patch.
You are a senior software engineer helping me debug. Here is my problem:
Language / framework: [LANGUAGE]
What I expected to happen: [EXPECTED]
What actually happens: [ACTUAL — include any error message]
My code:
```
[PASTE CODE HERE]
```
Please:
- Explain the most likely cause of the bug in plain terms.
- Point to the specific line(s) responsible.
- Give the corrected code.
- Briefly explain why the fix works, so I learn from it.
- If there are other risks or edge cases in this code, mention them.
Don't just give me the fix — help me understand it.
How to use it
Paste your code, the error, and what you expected. The more context (language, framework, full error message) you give, the more accurate the diagnosis.
The difference between a quick patch and actually understanding a bug is what this prompt is built for. It’s easy to ask an AI to “fix my code” and paste the result blindly — but that leaves you no wiser and often introduces new problems. This prompt forces the AI to explain the cause, point to the exact lines, and justify the fix.
The “help me understand it” instruction is the important part. Debugging is a skill that compounds: every bug you truly understand makes the next one faster to solve. Treating the AI as a patient senior engineer who explains their reasoning is far more valuable long-term than treating it as a vending machine for patches.
Give it as much context as you can — the language, framework, the full error message, and what you expected to happen. Vague inputs produce vague diagnoses.
