It generates a PostNitro post from the article URL, schedules variants for LinkedIn and Instagram, then sends email notifications for the generated and scheduled outputs.\n\n### Setup steps\n\n- Configure the RSS Feed Trigger with the target feed URL and polling settings.\n- Add Google Gemini credentials for the AI Agent chat model and verify the structured output parser schema matches the expected article-angle format.\n- Configure PostNitro credentials and posting parameters for carousel generation, LinkedIn scheduling, and Instagram scheduling.\n- Connect Gmail credentials and set the recipients, subject lines, and message templates for both notification nodes.\n- Review the Limit node value to control how many AI-generated article angles are processed per RSS item.\n\n### Customization\n\nAdjust the AI prompt and structured parser schema to change the number, style, or format of content angles. Update the PostNitro nodes to target different platforms, schedules, or carousel templates."
