Aafiyanawab/contextflow ? reverse-engineered prompt

Build me a Flask based web app called ContextFlow that lets people connect GitHub repositories and then ask questions about them in a chat style interface. It should understand the repo context, detect the tech stack, and use that information to give better answers. I want user login with GitHub OAuth and email password login, plus role based access so there is a normal user area and an admin area. Add a semantic cache so repeated or similar questions do not hit the AI every time, and keep a repository inventory so the app can reuse discovered metadata. Include a simple admin console, repository diagnostics, and a protected metrics page for Prometheus and Grafana. Use PostgreSQL for data, OpenAI for the AI answers, and make it work locally with Docker and docker compose. Also set it up so it can be deployed with GitHub Actions and Kubernetes on AWS, and if you need to check current docs online for any setup details, go ahead.
