Gooserelayvpn Socks5 Tunnel

This skill teaches Claude how to set up GooseRelayVPN, a SOCKS5 proxy that tunnels TCP through Google Apps Script to your own VPS. The setup uses domain fronting (SNI shows www.google.com while talking to script.google.com) and end-to-end AES-256-GCM encryption, so Google never sees your plaintext traffic. You'd use this when you need to bypass restrictive firewalls or route traffic through Google's infrastructure without giving them the decryption keys. It covers the full stack: building or downloading the Go binaries, deploying the tiny Apps Script forwarder, configuring both client and server with matching tunnel keys, and scaling across multiple deployments when you hit the 20k daily call limit. The architecture is clever but requires maintaining your own VPS exit node.
