This workflow fetches live approval criteria from Notion, generates a structured checklist with AI, then uploads your full workflow JSON to Gemini for a detailed pass/fail review. Results are sent to your email as an HTML report.\n\n### How it works\n1. You upload your workflow JSON file and enter the template title via the web form.\n2. The workflow scrapes four official n8n Creator Hub Notion pages using the Splitbee API.\n3. Gemini AI reads the scraped guidelines and generates a structured approval checklist.\n4. Both the checklist and your workflow JSON are uploaded to Gemini Files API.\n5. A second Gemini call reviews your workflow against every criterion and scores it.\n6. The HTML review report is emailed to the address you provided.\n\n### Setup steps\n1. Add your **Google Gemini API** credential (used for criteria generation, file upload, and review).\n2. Add your **Gmail OAuth2** credential (used to send the results email).\n3.
