Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cookie-and-session-debugging

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 inspects cookies and requests through Chrome DevTools MCP, finds session losses, redirects and misconfigured cookies, then checks the cookie banner for consent compliance. You get a diagnosis of likely causes.
