Anthropic has introduced automated security reviews in Claude Code, enhancing code security through a GitHub Actions integration and the new /security-review command. These tools allow developers to identify and fix security vulnerabilities within their codebase, addressing issues such as SQL injection risks, cross-site scripting vulnerabilities, and insecure data handling from their terminal before code is committed. The GitHub action automates security reviews for new pull requests, ensuring a consistent and customizable security review process across teams, which integrates seamlessly with existing CI/CD pipelines. These features help catch vulnerabilities early, as demonstrated by Anthropic's own use of the system to identify and address security issues in their codebase before production. These automated security review features are now accessible to all Claude Code users, with documentation available for setup and customization.
