Agent Architecture
Four components that make an AI agent work
LLM Core

Brain: processes language and makes decisions
Tools
APIs, databases, browsers: the hands the agent uses to act
Hands: executes actions in the real world
Memory

Memory: maintains continuity across sessions
Orchestration
Planning loops, task decomposition, and self-reflection
Manager: coordinates multi-step workflows
