[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 run the cron job and handle the specific instructions regarding status, error messages, and success updates for the dynydns.sh script, follow these steps:

1. Run the provided ./cf-dyndns.sh command in your terminal on a schedule that fits well with your daily or weekly tasks.

2. To run it at a fixed interval without manual inputs (like adding new targets), you could consider running any interactive Python script like this:
``bash
python /root/.hermes/skills/cf-dyndns_interactive.sh 2>&1
`
This will ensure the output from
dynydns.sh is properly read by the cron job and not lost.

3. For error handling purposes, make sure to check the log files (e.g.,
/root/.hermes/skills/cf-dyndns.log) regularly for critical messages.
4. On successful updates or when encountering status messages indicating a change in outcome (as mentioned in your note about sending "NO_REPLY"), send the following message:
`
Message: dynydns.updated
`
Adjust this to match your channel IDs and preferences.

5. **Reminder:** If you're using interactive scripts, after each job completes:

`bash
. /root/.hermes/skills/cf-dyndns_interactive.sh
`

This will keep running the script until the schedule is stopped, ensuring that any outstanding messages or tasks are handled properly.

6. **Important Note:** Cron jobs should ideally only be used for one-time or periodic tasks whose outcome you anticipate in advance. Complex scripts may require more tailored solutions (like GUI clients or specialized automation tools).

**Tips and Variations:**

- Before running a script on schedule, make sure your dependencies are installed and configured correctly.

- To improve debugging and error handling capabilities:

`bash
python /root/.hermes/skills/cf-dyndns debug.py 2>&1
`

This adds additional debug information that can be helpful in diagnosing issues or understanding the script's behavior.

- If you're unsure about specific instructions, consider consulting the latest version of the
dynydns.sh` script, provided alongside it as per the original prompt.
