Schedule Trigger fires daily at 8 AM (or run manually to test)\n2. SerpAPI fetches the last 24h of news headlines\n3. A Code node builds a numbered digest; an IF node stops with an error if no news was found\n4. Llama 3.3 70B writes a Twitter post + LinkedIn post as JSON\n5. Pollinations.ai generates a 1024x1024 image from the Twitter post\n6. The image is uploaded to Google Drive and made public\n7. Posts + image URL are appended to a Google Sheet ('content' tab) and a run log ('logs' tab)\n8. Slack gets a success notification\n\n**How to use:** Run manually once to verify each step, then activate. Review generated posts in the Sheet before publishing them."
