Best ChatGPT Prompt for “Debug Code

ChatGPT responds best to Markdown-formatted prompts with role assignment, clear headers, and constraints placed at the end. It gives higher priority to end-positioned instructions, so placing your most critical requirements last produces significantly better results. This free template is optimized specifically for ChatGPT, achieving approximately 37% token reduction compared to unoptimized prompts while producing higher quality output.

Optimized ChatGPT Prompt

# Task
As an expert Python debugger, help me debug the provided Python code.

# Requirements
*   Analyze the code for logical errors, syntax mistakes, and potential runtime exceptions.
*   Identify 3-5 specific areas in the code that are likely causing the unexpected behavior.
*   For each identified area, provide a clear explanation of the problem.
*   Suggest concrete, actionable solutions or code modifications to fix each issue.
*   Include 1-2 illustrative examples of how the corrected code would behave differently.
*   Focus solely on the provided code and its stated unexpected behavior.

# Output Format
*   Use Markdown headers for each section: "# Identified Issues", "# Proposed Solutions", "# Example Corrections".
*   Present each identified issue as a bullet point.
*   For each issue, clearly state the line number(s) or code block involved.
*   Ensure all explanations and solutions are concise and easy to understand.
*   Do not include any introductory or concluding remarks outside of the specified sections.

Why This ChatGPT Prompt for “Debug Code” Works Better

When you type “Help me debug this code, it's not working as expected” into ChatGPT, it lacks structure — ChatGPT has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.

It uses Markdown headers to organize the task, adds bounded constraints (specific numbers, word counts, formats), and places the most critical instructions at the end — where ChatGPT pays the most attention.
