User
[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.

This Python script checks if there are any changes in the status of your DynDNS instances using a cron job. It then reacts based on whether such changes occur or not.
To prevent sending unnecessary messages, be sure to handle exceptions as shown and consider implementing logging mechanisms to store output for further analysis later on.
Here is how it could look:
python
import subprocess
# Define the check function
def check_status_no_change():
