simstudioai/sim ? reverse-engineered prompt

I want to build a platform for creating and managing AI agents. Think of it as a central hub or a "control center" for an AI workforce.

The main interface should be a visual, drag-and-drop canvas where you can design agent workflows. You should be able to connect different blocks, tools, and agents to build out a process. It needs to support connecting to various large language models like OpenAI, Gemini, and Anthropic. A really important feature is the ability for users to upload their own documents, creating a knowledge base that the agents can use to answer specific questions.

To make it really user-friendly, include a "copilot" feature within the app. This AI assistant should help users build and fix their workflows using natural language commands. Please build this as a modern web app, and get it set up to run locally using Docker.
