Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cors-policy-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 configures CORS for Express, Next.js or Fastify: response headers, OPTIONS preflight handling, credentials and the list of allowed origins, with dynamic validation when needed. It applies cautious security rules. You get a configuration to test from your front end.
