The public path exits to Cloudflare and NPM to reach a k3s service on the same machine most sessions run on, which imposes rate limits and message-size caps on tool results. Serve terminates TLS with a real Tailscale cert and proxies to the NodePort over loopback, so traffic reaches the service from koala itself and satisfies the default-deny-ingress NetworkPolicy with no cluster change. Clients need 'tailscale set --accept-dns=true' for the MagicDNS name to resolve; see mathias/skills#24.",
