How to Automate Code Review with LFM2.5, Kitesurf, and Code-Testing-Generator

How to automate code review with modern LLMs

If you’re wondering how to automate code review today, the answer is simple: leverage new agentic models like Liquid AI’s LFM2.5, Cloudflare’s Kitesurf agent browser, and Microsoft’s open-source code-testing-generator. With the right prompts, you can achieve automated, consistent, and production-ready code reviews in just a few seconds.

Why AI-driven code review is essential in 2026

Software code is becoming increasingly complex, and development teams struggle to keep up with manual reviews. Next-generation agentic LLMs offer:

• Automatic detection of bugs, security issues, and anti-patterns
• Contextual correction and fix suggestions
• Native integration with existing workflows (Git, CI/CD, IDE)

These models can execute tools, read files, and write patches, transforming code review from a manual task into an automated, prompt-based process.

Key tools you’re using (or should be using)

LFM2.5 is a 2.69 billion parameter model that can plan, call tools, and complete multi-step tasks entirely on-device. Its 128K token context window makes it ideal for analyzing entire repositories.

Case study:A development team integrated LFM2.5 into a Git pre-commit hook and now achieves low-risk style and security checks in under 200 ms.

Kitesurf runs a stateless browser in V8 within Cloudflare Workers. It’s perfect for running rendering tests, checking links, and capturing screenshots of dynamically generated pages without a traditional browser.

Case study:A SaaS product used Kitesurf to verify that new UI components met accessibility standards, reducing false positives by 35%.

Open source in the dotnet/skills repository, this agent generates unit tests in multiple languages with a 92.1% task completion rate, compared to 78.9% for stock Copilot. It can read source code, generate test cases, and even integrate tests into the repository.

Creating effective prompts for automated code review

The quality of code review depends on the clarity of the prompt. Below is a template that works with LFM2.5, Kitesurf, and code-testing-generator.

Prompt for security and style review

# Input: file path, source code content, target language # Goal: Provide a lint-style security review with fix suggestions Analyze the following source code for: 1. Common security errors (e.g., injection, insecure input handling, secret exposure) 2. Code style violations (e.g., line lengths, naming conventions) 3. Language-specific best practices Return a structured list with: - Severity (High/Medium/Low) - Error message - Suggested fix code File: {file_path} Language: {language} Code: ``` {source_code} ```

Prompt for auto-generated tests

# Input: target function, framework used, preferred test style # Goal: Generate complete and executable unit tests Write unit tests for the following function using {framework} in {style} (e.g., xUnit, MSTest) style. Ensure each test covers a normal case, edge case, and error case. Return the complete, commit-ready test code, including namespaces and using statements. Function: {function_signature} Body: {function_body}

Integration into a CI/CD workflow

A practical way to get started is to add a pre-commit hook that invokes LFM2.5 for code review and code-testing-generator for tests. Here’s an example script for Git:

#!/bin/bash # pre-commit-hook.sh # Run security and style review with LFM2.5 node lfm-reviewer.js --file "$1" || exit 1 # Generate unit tests with code-testing-generator node test-generator.js --function "$1" --framework "xUnit" || exit 1 echo "Code review and tests completed successfully."

You can link this script to `.git/hooks/pre-commit` or integrate it into a GitHub Actions job.

Key takeaways

• Context-specific prompts.Include file path, language, and coding style to get more relevant results.
• Leverage built-in tools.LFM2.5 can call external tools; Kitesurf can render pages; code-testing-generator can write polyglot tests.
• Iterate on results.Use fix suggestions as a basis for further manual improvements and retrain the model with your domain for greater accuracy.
• Control costs.On-device models like LFM2.5 minimize inference expenses; still monitor API usage for Kitesurf and code-testing-generator.

Next steps for your team

1. Install LFM2.5 in your development environment (follow Liquid AI’s guide).
2. Configure a Kitesurf agent on Cloudflare Workers for UI testing.
3. Add code-testing-generator to your dotnet/skills repository.
4. Write a basic prompt like the ones above and test it on a small project.
5. Automate the entire workflow with a pre-commit hook or CI job.

Conclusion

Automated code review is no longer a futuristic experiment; it’s a concrete reality in 2026, thanks to agentic LLM models like LFM2.5, the agent browser Kitesurf, and Microsoft’s polyglot code-testing-generator. By creating targeted prompts and integrating them into your existing development processes, you can achieve faster, more secure, and scalable code review. Start today with a simple style review prompt and watch your review workflows transform into AI-driven, always-up-to-date, production-ready processes.
