Practical answers to setup and reliability concerns.

It reads RSS feeds specified in the Feeds tab of the Google Sheet; you can add any feed URL. The agent supports multiple feeds and scales as you add more. If a feed returns errors, it skips that feed for the run and continues with others. The log keeps a record of feeds attempted to help you audit issues. Any feed URL should be accessible publicly or through your credentials.

The AI agent compares fetched articles against the Published Articles log stored in the sheet. Articles not found in the log are treated as new. After posting, those articles are written to the log to prevent duplicates in future runs. If a link is duplicated across feeds, it is ignored. It uses pubDate or equivalent metadata when available to determine recency.

Yes. The AI agent supports a message template that you can adjust to include bold titles, clickable links, and a short summary. Formatting changes apply to all posts in the designated Slack channel. If you need per-feed customization, we can add feed-specific templates. Changes are reflected in the next automation run.

During a run, the agent skips feeds that fail to fetch. It records the failure in the log for visibility and retries on the next schedule. If a feed remains unavailable, you can configure a retry strategy or alert. The rest of the feeds continue processing as normal.

Posting details (title, link, and pubDate if available) are stored in the Posted Articles tab. This provides a single source of truth for what has already been shared. The log helps you audit and prevents duplicates across runs. You can export the log for records or reporting.

Yes. The schedule is defined by a Cron trigger and can be adjusted to run daily, hourly, or at a custom time. Changes are saved in your AI agent workflow configuration. If you need different schedules per feed, we can implement conditional scheduling.

The AI agent includes basic error handling and retry logic for transient failures. If credentials fail, it generates a clear alert and stops the run to prevent partial posts. Retried attempts follow a backoff policy to avoid rate limiting. You can monitor and adjust retry counts as needed.
