Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cac-roas-spend-health-check

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 computes the CAC and ROAS metric family, stating variant, window and source, then compares each value with three references in strict order: your break-even, your own history, and external benchmarks labelled as such. It returns a verdict: healthy, watch, concerning or insufficient evidence. You get a reasoned health check.
