Introducing Code Review Agent in Immunefi Magnus

Code reviews remain one of the most important parts of software development. In web3, they ensure the integrity of code that holds real value, a critical step if you’re securing value onchain. But reviews are still slow, manual, and come at a cost - engineers lose 20 - 40% of their time fixing bugs and reworking “finished” code.

Human-led reviews provide depth, but they depend on resource allocation. For many organizations, confidentiality concerns also make it hard to share sensitive code with external engineers. The result is a bottleneck that slows execution and limits visibility into security risk. Late stage fixes also come at a high cost, 10-100x more expensive when issues are discovered during an audit or in production.

Code Review Agent changes all of this.

It introduces AI-powered automation to PR Reviews in Magnus, allowing you to find and fix vulnerabilities as you code. 

Security that matches development speed

When a pull request is created, Code Review Agent automatically analyzes the changes and posts its findings as structured comments within GitHub.

Each finding includes:

• A description of the issue
• The affected code
• Suggested mitigations, when available

Developers receive clear, actionable feedback within minutes, without changing their workflow. Reviews complete faster, and teams do not need to upload code to a separate tool.

The process mirrors the format of human-led PR Reviews but runs continuously and at scale, allowing teams to identify vulnerabilities early and keep shipping without compromise.

How to use Code Review Agent

Using Code Review Agent is simple:

1. Go to the PR Reviews in Immunefi Magnus
2. Enable AI PR Reviews for your repository
3. Create a pull request
4. Review the findings posted automatically in GitHub

Each finding appears as a comment directly in the pull request, allowing you to read a summary report describing the issue and its potential impact, review the detailed explanation, and apply fixes.
