This article argues that chat APIs alone are insufficient for AI agents; true agent systems require execution environments, tool loops, multi-tenant isolation, and layered architecture to move from demo to production-grade reliability across multiple entry points.
The article introduces the ETCLOVG framework—a standardized seven‑layer architecture that separates structural core functions from control‑plane capabilities, detailing each layer's purpose and how together they define the essential engineering abilities required for robust, production‑level AI agent systems.
This article provides a detailed side‑by‑side evaluation of Hermes Agent and OpenClaw, covering their architecture, skill systems, memory mechanisms, model support, execution environments, programming capabilities, installation costs, migration tools, and offers a decision tree to help users choose the most suitable AI agent for their workflows.
