Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cors-csp-security-headers

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 configures CORS (origins, methods, credentials, preflight), security headers with Helmet.js or Spring Boot (Content-Security-Policy), CSRF protection and secure cookies. It does not cover authentication tokens or encryption.
