Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sign-in-with-google-web-security

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 chooses an architecture aligned with IETF recommendations, favoring a backend for frontend (BFF). It sets up the button and One Tap, verifies ID tokens on the server and applies CSP, COOP and Permissions Policy directives. You get integration code and a security checklist.
