dockerfile

Generate production-ready Dockerfiles or validate existing ones against security and performance best practices. Produces multi-stage builds with non-root users, health checks, optimized layer caching, and proper .dockerignore files.

Content Loading

Load each step through the fetch command (handles caching, decryption, and auth):

"~/.composure/bin/composure-fetch.mjs" skill shipyard dockerfile {step-filename}

Do NOT read cache files directly — they are encrypted at rest. Always use the fetch command above.
