# 2. Enter the 6-digit code you receive via SMS
/tocsin:sms-pair 123456

Remote/Batch Mode (After Pairing)

Once your device is paired, you can use Claude in non-interactive mode:

# Start a remote session with SMS monitoring
# The plugin continues monitoring even after Claude exits

Alternatively, you can stay in interactive mode:

# Start interactive session with monitoring

# Do your work...

# Stop monitoring when you're done
/tocsin:sms-unpair
