Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install docker-image-build-hardening

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 helps you build container images: multi-stage Dockerfiles, minimal images (Alpine, distroless, scratch), hardening, layer cache management and registries. You get a corrected Dockerfile and a checklist before production.
