Summary & Key Takeaways ​

• An "agent harness" is a software component in AI systems.
• It manages the loop between an AI model and its associated tools.
• The harness defines the context in which the AI operates.
• It also sets permissions and limits on what users can do with the agent.
• This concept is crucial for understanding the control and capabilities of AI agents.

Our Commentary ​

This definition of an "agent harness" is really helpful, especially when we're talking about "agentic engineering." It clarifies the underlying mechanism that controls these AI systems. It's a good reminder that even autonomous-sounding agents still operate within defined boundaries, which is both reassuring and a little concerning depending on who sets those boundaries.
