[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.

In this example output, the DynDNS server is registering or updating at specific times (2023-01-31 and 2024-02-30 for success, March 2nd in April 2024; 2023-02-21 for no change, February 28th in March); the status of each call can be indicated by 'NO_CHANGE' if it has not been completed or 'ERRORdynns-not-responding' or 'OK:dydns-registered OK' indicating that DynDNS is responding successfully.

To send notifications based on this output:

You could create code to extract and send messages for certain statuses:
`python
import sys

# Check current status of dynns
status = "NO_CHANGE"
if not any(status == line[1] for line in sys.stdin.readlines()):
print("Sending NO_REPLY")
sys.exit(0)
elif status == "ERRORdynns-not-responding":
print("Sending ERROR message")
else:
print("Sending OK message")

# Run this command to run and send notifications
