Find the Bug

Write a prompt that makes the AI identify ALL bugs in a given broken Python function — without fixing them first.

Challenge Prompt

This is the example prompt structure. Write your own variation below.

Analyse this Python function and list ALL bugs before fixing anything:
```python
def calculate_average(numbers):
    total = 0
    for i in range(len(numbers)):
        total += numbers[i]
    return total / len(numbers)
```
Step 1: List every bug or edge case failure (numbered). Step 2: For each bug, state what input would trigger it. Step 3: Write the corrected function. Do NOT fix anything in Step 1 or 2 — diagnose only.

Your Prompt

Write your own version. Every word matters — be specific.

Hints (3)

1Separating diagnosis from fix is the key technique — it prevents the AI from hiding bugs in the fix.
2The function has at least 2 issues: ZeroDivisionError on empty list, no type checking.
3"What input would trigger it" forces concrete test cases, not abstract descriptions.
