AI prompts for coding
AI is genuinely useful for code, but only when you tell it what "good" looks like. A prompt that names the language, the constraints, and the kind of answer you want turns a generic reply into a review you can act on. These prompts do that setup for you.
Grab a prompt, drop in your own code or context where marked, and paste it into your AI tool. Each one is free and works in ChatGPT, Claude, and Gemini.
7 coding prompts
- Review my codePasting code and asking "is this good?" gets you a vague thumbs-up. This prompt makes the model review like a senior engineer: it finds real bugs, flags edge cases, and gives you prioritized, specific feedback instead of generic praise.
- Explain codePasting code and asking "what does this do?" often gets you a vague overview. This prompt explains it clearly, at the level of detail you choose, so you actually understand it.
- Debug an errorPasting just an error message gets you a guess. This prompt gives the model what it actually needs to debug well: the error, the code, and what you expected, so you get a real diagnosis and a clean fix.
- Write testsAsk an AI for tests and you often get one test for the happy path. This prompt makes it cover what actually matters: edge cases, invalid input, and the failures that break things in production.
- Write a regexRegex is easy to get slightly wrong and hard to read. This prompt writes the pattern, explains every part, and shows you exactly what it matches, so you can trust it.
- Write a SQL queryDescribing what you want in plain English is easy; getting the joins and grouping right is not. This prompt turns a plain description into a correct, readable SQL query, and explains it so you can trust and adapt it.
- Document codeBad code comments just restate the code. Good ones explain why it exists and what to watch out for. This prompt documents your code the useful way, capturing intent and edge cases, not just the obvious.
