[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]

Run this command and follow the instructions below:

bash /root/.hermes/skills/cf-dyndns.sh 2>&1

- If the output contains "STATUS:NO_CHANGE": Send NOTHING. Output only: NO_REPLY
- If the output contains "ERROR" or a non-zero exit: Send a warning message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "⚠️ DynDNS Error: [error output]"
- If the output shows successful updates (lines with "->" or "OK:"): Send an update message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "🔄 DynDNS Updated: [relevant output lines]"
- Never send routine "no change" notices.

To monitor the DynDNS update process, it is recommended to use a combination of the following approaches:

1. **Status Checker Output**: To determine if an update was successful or not, observe the status of the operation from the provided output. This can help in verifying whether the DynDNS system updated successfully.

2. **Notify When Changed**: Set up notifications for changes in the status as determined by a specific threshold. Depending on your requirements, you might need to configure how and which types of messages are sent or triggered when an update is detected and the desired outcome (like sending "UPDATE:NOTIFICATION message") happens.
3. **Alerts via Telegram/Patents Discord**: In cases where only two people receive updates about changes in status but it's critical that one receives notifications directly and others not should be advised how to receive these messages or where they should be placed so as to provide the required information.

Here is a code snippet using bash, which can be run by navigating into the directory you have your cron script in to make sure execution only happens when a file exists:

``bash
#!/bin/bash

# Example of writing error message that will trigger sending an update notification.
read ERROR_MESSAGE <<< "$1"
send_notification "[$timestamp] DynDNS Error:\n$ERROR_MESSAGE" "tg$2" "disc$3"

if [[ $? == 0 ]]; then # Check if the operation was successful
send_update Notification: Updated DynDNS ($ERROR_MESSAGE) $timestamp | mail -s "DynDNS System Update" -r "$1" 1003980922525
else
send_notification "[$timestamp] DynDNS Error:\n$ERROR_MESSAGE" "d$2" "disc$d3"
fi
``

When executed correctly, the above command will output a message indicating whether an update was successful or not. If there is no output for a minute (to wait until it stops updating), then it has successfully sent "UPDATE:NOTIFICATION", but if any other status is returned to your expected value it has triggered a failed send notification.
