Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sendgrid-inbox-placement-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 qualifies the problem (spam, bounces, provider blocks, new IP), checks domain authentication, then proposes fixes based on bounce and complaint thresholds. It does not cover Twilio Email.
