reworkd/AgentGPT ? reverse-engineered prompt

Build me a web application that lets me create and deploy my own autonomous AI agents, similar to AutoGPT. I want a simple UI where I can give an agent a name and then assign it a high-level goal, like "plan a marketing campaign for a new coffee shop."

Once I start it, the agent should be able to think for itself, breaking down the goal into a series of tasks, executing them, and learning from the results. For example, it should be able to perform web searches to gather information. I want to be able to watch its progress in real-time, seeing its thought process and the actions it's taking.

Let's use a modern tech stack. A Next.js and TypeScript frontend would be great, with a backend in Python using FastAPI. The system will need to connect to OpenAI, so create it to use an API key. You can use LangChain to manage the agent's logic. Please also set up the project with Docker so I can easily run everything locally.
