Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install docker-container-subagent

First time: connect the CLI with

npx --yes palatekit@latest login

This subagent writes and improves Dockerfiles: multi-stage builds, layer caching, slim base images, non-root users, vulnerability scanning and secret handling. It also prepares docker-compose files. The main agent calls it for an image to slim down, secure or make reproducible.
