wassupjay/n8n-free-templates ? reverse-engineered prompt

Build me a simple GitHub repo full of free n8n workflow templates that people can import and use right away. I want the workflows grouped into clear categories like AI, finance, ecommerce, devops, social media, and more, with each template saved as a JSON file and a short README explaining what it does and what services it needs. Make it feel plug and play, so someone can download a workflow, add their credentials, and activate it without a lot of setup.

A lot of the templates should use modern AI tools too, like OpenAI, Claude, embeddings, vector databases, and basic RAG style workflows, plus useful automations like alerts, logging, OCR, polling, and Google Sheets or Slack. Keep it practical and ready for demos or real use, and if any workflow is incomplete, leave a clear note so it can be finished later. If you need to check current n8n workflow export details, look up the latest docs online.
