Decide Whether to Extract a Shared Module or Just Copy the Code One More Time

Coding Architecture Advanced 🤖 ChatGPT 👁 3 views

📝 The Prompt

I have a piece of logic that now appears in three places across our codebase. I'm tempted to extract it into a shared module, but I remember the rule: 'duplication is far cheaper than the wrong abstraction.' Help me decide if this is the third copy I should extract, or if I should let it live as three copies a bit longer. Ask me five questions about the three call sites: how similar are the inputs, how similar are the outputs, do they evolve together or independently, who owns each call site, and what's the failure mode if one changes. Then tell me whether to extract, copy again, or extract with a deliberately narrow interface.

🎯 What this prompt does

This AI prompt helps you decide whether to extract a shared module or just copy the code one more time. Designed for architecture workflows in the coding category, it's a advanced-level prompt you can copy directly into ChatGPT to get instant, production-ready results.

Use it when you need a advanced prompt that produces clear, actionable output without wrestling with trial-and-error wording. Just copy, customize, and run.

🚀 How to use this prompt

  1. Copy the prompt using the 📋 button above.
  2. Open ChatGPT (or Claude, Gemini, Perplexity, or your preferred LLM).
  3. Paste the prompt into a new chat. Add any extra context about your situation if helpful.
  4. Run the prompt and review the AI's response. Most outputs are usable immediately.
  5. Iterate if needed — if the tone, length, or structure isn't quite right, reply with "make it shorter", "use bullet points", or "make it more formal" and the AI will refine it.

💡 Tips for better results

  • Tailor the prompt to your specific context — the more detail you give, the better the output.
  • If the first output isn't quite right, ask the AI to refine, rewrite, or add more detail — iteration is key.
  • For long outputs, ask for a section at a time (e.g. 'start with the introduction only') to keep quality high.
  • Combine this with other coding prompts to build an end-to-end workflow.
  • Save your favorite variations — small wording tweaks often produce noticeably different results.

Need a different angle? Just ask follow-up questions. The AI will adjust without you starting over.

🔄 3 variations to try

1

Make it more formal

Add "Use a formal, professional tone suitable for enterprise clients" at the start of the prompt.

2

Ask for multiple options

Append "Give me 5 alternative versions, each with a different angle or approach." after the main instruction.

3

Request structured output

Add "Return the response as a markdown table (or bullet list, or JSON)" so you can paste the result directly into your docs or code.
