The AI agent loop, in ~150 lines (no framework)

The essence of an "AI agent" is distilled down to a simple loop, demonstrating that sophisticated AI interaction can be achieved without relying on complex frameworks. This core loop involves sending conversation data to a model, running tools when necessary, and repeating the process until a complete answer is formed. This insight highlights the fundamental mechanics of AI agents, emphasizing that simplicity can drive powerful results, challenging the notion that extensive frameworks are always required for advanced AI applications.
