Best AI Prompt for Programming
Here’s a sample of my existing code style: [paste a representative snippet]. Write a [function or component, described specifically] that [does X], in [language, framework, and version]. Match the naming conventions, formatting style, and general patterns of the sample, and briefly explain any non-obvious design choices you make.
Getting genuinely usable code means giving the AI a style reference from your existing codebase, not just a task description — without it, the result is often technically correct but stylistically inconsistent with everything else in the project.
What this produces
Code matched to your project’s existing conventions — naming, formatting, and patterns — along with a brief explanation of any non-obvious choices, rather than generic textbook-style code that needs reformatting to fit.
Variations
Two ready-to-copy versions for different needs.
Here’s a sample of my existing code style: [paste a representative snippet]. Write a [function or component, described specifically] that [does X], in [language/framework and version]. Match the naming conventions and formatting style of the sample exactly. Briefly explain any non-obvious choices you make.
Here’s my code: [paste code]. It should [expected behavior] but instead [actual behavior or error message]. Identify the likely cause and suggest a fix that matches the existing code style, explaining clearly why the bug happens so I can avoid it next time.

FAQ
Should I always paste a code sample?
For anything going into an existing project, yes — it’s the single biggest factor in getting code that fits without manual reformatting. For a standalone script, it matters less.
Can this help with code review, not just writing new code?
Yes — paste the code and ask specifically for a review focused on bugs, edge cases, or readability, rather than asking it to just rewrite everything.
What if I’m not sure what’s causing a bug?
Paste the code, the expected behavior, and the actual behavior or error message — being specific about the symptom helps narrow down the cause much faster than a vague “this doesn’t work.”
