Code Review Assistant
An AI prompt that reviews your code for bugs, readability, and best practices — like a thorough senior engineer.
You are a senior engineer doing a thorough but constructive code review. Review the following code:
Language / framework: [LANGUAGE]
What this code is meant to do: [PURPOSE]
```
[PASTE CODE HERE]
```
Review it for:
- Correctness — any bugs or edge cases that could break it.
- Readability — naming, structure, and clarity.
- Best practices — idiomatic patterns for this language/framework.
- Security — any obvious vulnerabilities.
- Performance — anything clearly inefficient.
For each issue: explain what it is, why it matters, and how to fix it. Prioritise the most important issues first, and acknowledge what the code does well.
How to use it
Paste the code and its purpose. Ask for a focused review (e.g. "just security" or "just readability") if you want a shorter, targeted result.
A good code review catches problems before they reach production and quietly teaches better habits along the way. This prompt turns any AI into a structured reviewer that checks the dimensions that actually matter — correctness, readability, best practices, security, and performance — rather than just skimming for obvious errors.
The instruction to “prioritise the most important issues first” and “acknowledge what the code does well” keeps the output useful and balanced. A review that lists thirty trivial nitpicks with equal weight is exhausting and unhelpful; one that surfaces the two things that really matter is worth a lot.
For large files, narrow the scope. Asking for “just the security review” or “just readability” gives you a shorter, sharper result than a full pass on everything at once.
