fabricioveronez/boilerplate-copa-aiops — reverse-engineered prompt

Build me a starter app for an AI ops assistant that I can run locally and use as the base for a real project. I want a simple web page with a dark theme, a FastAPI backend, and an agent powered by Claude Sonnet through LangChain. The agent should be set up in the ReAct style and be ready to call external tools through an MCP server, especially a local Kubernetes MCP endpoint. Please wire in Postgres so the app can persist data, include migrations, and keep the code organized so I can later add models, collector jobs, and more agent logic.

Make the app boot cleanly with a health check, a homepage, environment based config, and clear local run steps. Use Docker Compose only for the database and pgAdmin, and assume the Kubernetes MCP server runs separately with Node and npx. Keep it practical and easy to extend, not overengineered. If anything is unclear, check the current docs online and make sensible defaults.
