An AI Agent Harness - The execute layer

Many people focus on the AI model when building agent systems.

But the real infrastructure that makes AI agents work reliably is something else: the Agent Harness.

Think of modern AI architecture like a computer system:

• Model = CPU → reasoning engine

• Context Window = RAM → temporary working memory

• Agent Harness = Operating System → execution orchestration

• Agent = Application → task-specific logic

The Agent Harness manages tool calls, controls environments, handles errors, and coordinates interactions with databases, APIs, and external systems.

💡 In short:

The model decides. The harness executes.

Understanding this layer is critical for building production-grade AI agents that can operate beyond simple chat responses.
