# Mobile-friendly Claude Code re-authentication
# Designed for use via SSH from Termux

# This script handles the authentication flow in a way that works
# from a mobile device by:
# 1. Checking if auth is needed
# 2. Running claude setup-token for long-lived auth
# 3. Outputting URLs that can be easily opened on phone
