Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install email-deliverability-diagnosis

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 engagement, reputation, infrastructure (SPF, DKIM, DMARC) and list health signals, then runs a step-by-step procedure. You get a diagnosis of likely causes and an action plan to recover inbox placement.
