Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install docker-container-development-security

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 writes or optimizes Dockerfiles and docker-compose files with multi-stage builds, a non-root user and an Alpine or slim base image, then checks versions and OCI labels. You get smaller and safer images.
