A scheduled trigger then reads the sheet every day at 10 AM, filters only that day\u2019s standups, and checks whether any updates were submitted. If standups exist, AI generates a concise team summary and posts it to Slack. If none were submitted, the workflow sends a fallback message to the same channel.\n\n## Setup steps:\n1. Configure the webhook path for standup submissions\n2. Connect Google Sheets and create columns for Timestamp, Name, Yesterday, Today, and Blockers\n3. Connect Gemini credentials for summary generation\n4. Connect Slack and select the target channel\n5. Set the schedule trigger time for daily summary posting\n6. Test webhook submission, sheet logging, and Slack delivery"
