Guides the development of secure, optimized, and production-grade Dockerfiles using industry-standard patterns.
This skill empowers Claude to create and audit container configurations with a focus on reproducibility, security, and performance. It provides expert guidance on selecting minimal base images, implementing efficient multi-stage builds, and optimizing layer caching for both local and CI/CD environments. By enforcing best practices such as non-root user execution, BuildKit secret management, and OCI-compliant labeling, it ensures that containerized applications are lean, secure, and ready for modern cloud-native deployment.
