Google Open-Sources Mantis: A Modular Skills Toolkit That Lets Coding Agents Find, Reproduce and Patch Vulnerabilities

Google has released Mantis, an open-source toolkit designed to automate the vulnerability management lifecycle for AI coding agents. The software allows agents to scan codebases, reproduce security flaws in sandboxed environments, generate patches, and verify the effectiveness of those fixes. By providing a standardized framework for these tasks, the tool aims to improve how automated systems identify and remediate software security issues across various development environments.
