Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install not-found-and-error-handling

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 sets notFoundComponent on the root, calls notFound() when a resource is missing, sets the fuzzy or root mode, and adds per-route error components. You get consistent 404 and error pages, without the deprecated NotFoundRoute.
