Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install container-image-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 reduces the base image, removes unneeded packages and switches the container to a non-root user with a read-only filesystem. It also covers runtime security options and Kubernetes security contexts. You get a hardened Dockerfile and security context.
