25 AI Prompts for Developers

Ready-to-use AI prompts for developers, organized by the task you’re actually doing. Click a tab, copy a prompt, adapt it to your codebase.

AI prompts for developers organized by task

Tap a category below to see prompts for that task.

Generic “write me code” prompts waste the real power of a good AI coding assistant. These AI prompts for developers are built around specific tasks — debugging, review, documentation, and learning — with enough context built in to get a useful answer on the first try.

How to use these: swap in your actual error message, function, or file before sending — these are templates, not magic words. Our prompt engineering guide covers the principles behind why these particular prompts work.

Pick a Category

Debugging Prompts

Paste the error and relevant code below each prompt.

“Explain why this function throws [error message], step by step, then suggest a fix. Here’s the code: [paste code]”
“This output doesn’t match what I expect. Expected: [X]. Actual: [Y]. Walk through the logic and find where it diverges.”
“Review this function for edge cases I might have missed — empty inputs, null values, and off-by-one errors specifically.”
“I’ve narrowed this bug to one of these three functions. Review each and tell me which is the most likely cause, with reasoning.”
“Suggest two or three console.log statements I could add to quickly confirm where this value changes unexpectedly.”

Code Review Prompts

Use these before opening a pull request, or on someone else’s code with permission.

“Act as a senior developer reviewing this code for security issues. List only critical problems, in priority order: [paste code]”
“Review this function for readability. Suggest renames or restructuring that would make it clearer to a new team member.”
“Check this code for any obvious performance issues — unnecessary loops, repeated calculations, or inefficient queries.”
“Does this function handle errors gracefully? Point out any place it could fail silently or crash unexpectedly.”
“Compare these two implementations of the same function and explain the real trade-offs between them.”

Documentation Prompts

Keep docs close to the actual code — paste the function or file directly.

“Write a clear docstring for this function, including parameters, return value, and one usage example: [paste code]”
“Write a README section explaining what this project does and how to run it locally, based on this code: [paste code]”
“Summarize what this file does in 2-3 sentences, suitable for a new developer joining the project.”
“Generate example API requests and responses for this endpoint, based on the function signature: [paste code]”
“Turn these code comments into a proper CHANGELOG entry describing what changed and why.”

Learning Prompts

Useful when exploring an unfamiliar codebase, library, or concept.

“Explain what this code does, line by line, as if I’m new to this language: [paste code]”
“I understand the basics of [concept]. Explain [related advanced concept] by building on what I already know.”
“What’s the idiomatic way to do [task] in [language]? Compare it to how I’d naturally approach it coming from [other language].”
“Quiz me on [topic] with 5 questions, one at a time, and tell me if I’m right before moving to the next.”
“Explain the trade-offs of using [library A] vs [library B] for this specific use case: [describe your project].”

How to Adapt These Prompts

Every prompt above works better with real specifics swapped in — your actual error message, the real function name, the specific library versions you’re using. The structure (role, context, specific ask) is what matters; the exact wording is just a starting point.

Common Mistakes When Prompting for Code

  • Pasting code with no context about what it’s supposed to do or what’s going wrong.
  • Accepting the first answer without verifying it against your actual codebase and conventions.
  • Asking for a full solution when a step-by-step explanation would teach you more for next time.
  • Not specifying the language or framework version, leading to outdated or incompatible suggestions.

Frequently Asked Questions

Do these prompts work with any AI coding assistant?

Yes — the structure works across Claude, ChatGPT, and similar tools, though response quality and context-window limits vary between them.

Should I paste my whole file or just the relevant function?

Start with just the relevant function or section — it keeps the context focused. Add surrounding code only if the AI’s response suggests it’s missing important context.

Is it safe to paste proprietary code into an AI tool?

Check your company’s policy first — many organizations have specific guidelines or approved tools for this, since code can contain sensitive business logic or credentials.

Good AI prompts for developers aren’t about magic phrasing — they’re about giving the model the same context you’d give a human teammate: what you’re trying to do, what’s actually happening, and where you’re stuck.
