Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install linux-server-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 checks the distribution and current configuration, then proposes SSH, account and sudo changes to preview before any reload. You get a hardening plan with backups and a fallback access path, to validate before applying.
