Structured as 18 progressive steps across four phases, this tutorial teaches event-driven agent architecture, multi-agent routing, persistent memory, and production scaling—progressing from a basic chat loop to a distributed system with scheduled autonomy and WebSocket support. It uses LiteLLM for multi-provider LLM compatibility and emphasizes skill extension via markdown files, conversation compaction, and hot-reload configuration. Each step includes runnable code and design documentation, with a reference implementation (pickle-bot) demonstrating the full pattern.
