Streamlined OAuth-login handling (forward fixed callback ports) - #15
Merged
Conversation
Browser-OAuth CLIs redirect to a localhost callback port that a headless box can't receive. Pre-forward the two agents' fixed callback ports (Claude 54545, Codex 1455) in the mac-ssh-config snippet so their logins complete over the tunnel transparently; document the on-demand 'ssh -O forward -L port devbox' one-liner (adds a forward to the live ControlMaster connection, no reconnect — verified over Tailscale SSH) for any other tool, and the device-code/token flows that avoid forwarding entirely. README 'Logging into other tools later'. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Why
Browser-OAuth CLIs open a
localhost:<port>callback the browser must reach — impossible on a headless box, which is the friction the user hit.What
Researched + verified the current best approach (fixed callback ports; on-demand forwarding over ControlMaster):
