Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install fastify-oauth-pkce-setup

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 installs the plugins, registers the authorization code flow with PKCE, handles the callback, adds JWT validation and refresh token rotation, then protects the routes. You get login code and a security checklist.
