Keeping code secure is becoming more critical as developers build faster and more complex systems with AI help. I recently came across some exciting news about Claude Code‘s new automated security review features that streamline vulnerability detection right into your development workflow. These tools promise to catch issues before they ever reach production — a crucial step for anyone serious about shipping safe software.
Security reviews from your terminal? Yes, please!
One particularly cool capability is the new /security-review command. You can run it directly from your terminal, giving you an instant audit of your code’s security. Claude scans for common risk patterns such as SQL injections, cross-site scripting (XSS), authentication flaws, insecure data handling, and dependency vulnerabilities. What’s brilliant is that after flagging these issues, Claude can also suggest fixes — effectively letting you patch problems right away.
This command keeps security reviews in your inner development loop, catching issues early when they’re easiest to fix.
Security reviews that integrate with your pull requests
Taking automation a step further is a GitHub Action that automatically reviews every pull request. Once set up, it scans your new code for vulnerabilities and posts inline comments right on the pull request with detailed explanations and fix recommendations. It also lets you customize rules to reduce noise from false positives or known issues. Imagine the peace of mind from knowing every PR meets a baseline security standard before merging.
This isn’t just theory. Claude Code‘s own team uses these tools internally and has caught multiple critical vulnerabilities before they ever shipped. One example involved identifying a remote code execution risk linked to DNS rebinding in an internal HTTP server feature — caught and fixed before merging. Another was flagging a server-side request forgery (SSRF) vulnerability in a proxy system designed for credential management. These concrete use cases highlight how automated reviews can prevent serious security incidents.
Getting started and what it means for your workflow
If you want to embed these security checkpoints into your daily coding routine, both features are already available to Claude Code users. The /security-review command can be accessed simply by updating to the latest version and running the command in your project directory. For teams, the GitHub Action integrates smoothly into existing CI/CD pipelines, with flexible configuration options to align with your security policies.
It’s clear that embedding automated security checks right where developers work can significantly cut down on the risk of vulnerabilities slipping through. The combination of instant terminal reviews and automated pull request analysis creates a robust safety net — keeping your code both agile and secure.

Key takeaways
- The
/security-reviewcommand offers instant, in-terminal scanning for common vulnerabilities and suggested fixes. - The GitHub Action automates security reviews on all pull requests, making sure no code goes unvetted before merging.
- Real-world cases prove automated reviews can catch critical risks early, preventing costly security mistakes.
If you’re working with Claude Code or looking for ways to strengthen your security game without slowing development, this approach is definitely worth exploring. Staying secure while shipping faster isn’t a trade-off anymore — it’s becoming the new standard.
Getting started
Both features are available now for all Claude Code users. To start using automated security reviews:
For the GitHub action: See the documentation for step-by-step installation and configuration instructions
For the /security-review command: Simply update Claude Code to the latest version and run /security-review in your project directory. See the documentation to customize your own version of the command
