AI Agents from Scratch

A practical, ground-up introduction to AI agents. Understand the ReAct loop, tools, orchestration, memory, and evaluation, then build real agents using Aurora Trading Agent platform as your lab.

  • Explain the difference between a bare language model, a chatbot, and an AI agent
  • Describe the ReAct loop (Thought → Action → Observation) and why it makes agents agentic
  • Design tool-calling workflows and understand why tools, function calling, and MCP servers are all the same core concept
  • Use autonomy controls (whitelists, approvals) to safely run agents in production
  • Connect memory, scheduling, and subagents into a full autonomous workflow
  • Build traces and evaluators (including LLM judges) to measure agent quality
