sciro24/Agentic-SDLC — reverse-engineered prompt

Build me a polished app called Agentic SDLC that helps developers analyze a Python file with a small swarm of AI agents. I want a web dashboard where someone can enter their Google Gemini API key for just the current browser session, then paste code or drag and drop a .py file and get three results in parallel, clear Markdown documentation, a code quality audit with simple scores and feedback, and performance improvement suggestions with an easy side by side code diff.

Please make it feel premium and modern, with dark and light mode, nice typography, responsive layout, and visible loading steps that show which agent is working. The backend should be a stateless Python API and the frontend should be a clean Next.js app that can point to any deployed backend with an environment variable. Make privacy a core part of it, so the key is never stored and uploaded code is only processed in memory. Add solid error handling and sensible Gemini model fallback behavior. Look up current docs online if you need to.
