Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install email-dns-deliverability-setup

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 audits DNS records, drafts SPF, DKIM and a staged DMARC policy, then configures a transactional relay or Postfix. You get records ready to publish and a deliverability test plan.
