Optimizes Dockerfiles for minimal image size, maximum build speed, and hardened container security.
The Dockerfile Optimizer skill provides a systematic 8-check analysis to transform inefficient Dockerfiles into production-ready assets. By applying a two-pass approach, it evaluates base image selection, multi-stage builds, layer caching, and security protocols to ensure containers are lean, fast, and secure. It is specifically designed to help developers reduce CI/CD overhead and minimize the attack surface of their containerized applications.
