[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.

Here is a simple Python script that runs the command and reports on its output:

``python
import subprocess

# Execute the script with arguments
result = subprocess.run(["/root/.hermes/skills/cf-dyndns.sh", "2>&1"], check=True)

if result.returncode == 0:
# Output contains "STATUS:NO_CHANGE" so no reply needed.
print("NO_REPLY")
else:
try:
output = result.stdout
if "ERROR" in output or result.returncode != 0:
print(f"WARNING: DynDNS Error ({result.stderr}) or exit non-zero status (0): {output}")
else:
print("UPDATE: DynDNS Updated:", output)
except Exception as e:
print(f"EXCEPTION: {e}")
`

This script reads the return code of the
cf-dyndns.sh command and checks if it contains "STATUS:NO_CHANGE". If not, a warning message is printed. Otherwise, an update message is printed along with the output returned by the command.

Also, please keep in mind that this script assumes
/root/.hermes/skills/cf-dyndns.sh` exists and is executable. You might need to make sure it exists and points to your dynDNS server's configuration file for this script to work correctly.
