What build tools does this support?

The skill includes specific optimizations for popular ecosystems including Node.js (npm), Python (pip), Go, and C/C++ development environments.

How does this skill reduce Docker image size?

It implements multi-stage builds, utilizes minimal base images like Alpine or Distroless, and chains RUN commands to ensure build artifacts don't persist in final layers.

Can it help speed up slow CI/CD pipelines?

Yes, it configures advanced caching strategies, such as BuildKit mounts and specific instruction ordering, to ensure that dependencies are only re-installed when necessary.

Does this skill address container security?

Absolutely. It provides patterns for implementing non-root users, stripping debug symbols, and using distroless images to minimize the attack surface of your containers.
