Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install next-js-runtime-verification

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 combines the /_next/mcp endpoint (routes, server errors, server actions) with agent-browser (DOM, console, network) to check the result after each edit. It requires a running next dev server and closes the session cleanly.
