Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install shadow-mode-traffic-validation

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 designs traffic mirroring to the new service and compares its responses with production, while users only receive production's answer. You get a check of the new system's behavior under real load.
