Keep a browser session alive to prevent token expiry:
# Start keepalive (keeps browser open, refreshes every 10min)
clippy keepalive --interval 10
For persistent operation, set up as a launchd service (macOS) or systemd (Linux).
Health monitoring: Keepalive writes to ~/.config/clippy/keepalive-health.txt on each successful refresh. Check if this file is stale (>15min) to detect failures.
