Cognition released three agent skills to detect and remediate recent vulnerabilities in PHP, Node.js and self-managed GitLab. They first inspect version pins and deployment configuration read-only, then modify only approved targets after checking that fixed images or packages actually exist. The workflow runs before-and-after tests inside the production image and prepares a focused pull request with risks, rollout steps and a rollback target. It supports multiple coding agents, but installing the skills does not itself patch systems or eliminate regression risk.
