Deconstructing AI Agent Architecture: Orchestration and Tool Layers

goyalshaliniuk · x · 2026-08-07

Breaks down core components of AI agent architecture. The Tool Layer enables models to interact with the outside world via APIs, databases, web search, and code execution, where the model decides and the tool acts. The Orchestration Layer acts as the control center, housing the classic agent loop: Understand goal → Plan → Choose tool → Execute → Observe → Update state → Repeat. It manages routing, retries, tool selection, and multi-agent coordination, marking the transition from simple prototypes to production systems.
