Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install docker-security-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 reviews your Dockerfile and runtime configuration, then proposes hardening steps: non-root user, read-only filesystem, dropped capabilities, seccomp profiles and secret handling. You get a checklist and a mapping to the CIS benchmark.
