Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install docker-image-optimization-2

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent reviews or writes the Dockerfile, separates build and final image with a multi-stage build, reduces image size, pins versions and avoids running as root. It also configures Docker Compose for development.
