Published July 4, 2026
Most people try to use AI for Gemini for Code Review with a single vague prompt and get generic results. This guide takes a different approach: 4 targeted stages, from Set up the review through Write review feedback, each with a prompt that gives the AI exactly the context it needs. Use Gemini to catch bugs, improve code quality, and speed up pull request reviews before human reviewers see the code. Works with ChatGPT, Claude, and Gemini.
Set up the review
Start here to frame what a good review looks like for this specific change.
Request a general review
Review this code for overall quality: [PASTE CODE]. Check for: bugs, edge cases, security issues, readability, and what a senior engineer would push back on. Prioritize by severity.
Review a PR diff
Review this code change: [PASTE DIFF]. Is the change correct? Are there bugs or missing edge cases? Is the approach right for the goal?
Review against criteria
Review this code against these criteria: [LIST YOUR STANDARDS OR PRINCIPLES]. Flag specific violations with the code location.
Create a review checklist
Create a code review checklist for [TYPE OF CODE: REST API / REACT COMPONENTS / DATABASE QUERIES]. What should every reviewer check?
Review for security
Review this code for security vulnerabilities: [PASTE CODE]. Check for: injection, auth issues, sensitive data exposure, and OWASP Top 10 problems.
Find bugs and issues
These prompts help you identify logic errors, edge cases, and security concerns.
Find logic bugs
Find logic bugs in this code: [PASTE CODE]. For each: what it does versus what it should do, and how to fix it.

Use these prompts to raise code quality, readability, and maintainability.
Review readability
Review readability: [PASTE CODE]. Which parts would confuse a new developer? Flag unclear names, complex logic, and functions that are too long.
Check over-engineering
Is this code over-engineered: [PASTE CODE]? What abstractions can be removed while still meeting requirements?
Review API design
Review the interface design: [PASTE CODE]. Are function signatures clear? Would a consumer understand how to use this without documentation?
Check consistency
Compare this new code to existing code: [PASTE BOTH]. Is the style consistent? What would need to change to fit in?
Review architecture
Review the overall structure of this code: [PASTE CODE OR DESCRIBE]. Are the components right? Is there a better architectural approach for this problem?

Frequently asked questions
What makes Gemini useful for code review?+
Gemini reads all the code you provide consistently and without fatigue. It catches common bug patterns, checks for security issues, and can apply specific review frameworks. It works best as a first pass before human review to catch the obvious issues.
Can Gemini review code in any language?+
Yes. Gemini works across Python, JavaScript, TypeScript, Java, Go, Rust, C#, and other mainstream languages. Specify the language and framework context for more accurate reviews.
Should Gemini replace human code review?+
No. Use it as a first pass. Human reviewers add knowledge of business context, team standards, and architectural judgment that AI cannot replace. The best workflow: AI review first, then human review focused on higher-level concerns.
Does Gemini integrate with GitHub for code reviews?+
Gemini can be integrated with GitHub through the Gemini Code Assist product for enterprise teams. For individual use, paste code from your PR into Gemini directly for review.
How do I give Gemini enough context for a useful review?+
Include: what the code is supposed to do, any relevant constraints (security, performance), and the broader system context. For framework-specific reviews, mention the framework and version.
