  "account": "The agent harness is an emerging concept in AI, introduced this year, that encompasses everything built around the core model to create a production-ready AI agent. It includes components such as memory, tool access, model routing, guardrails, cost controls, and observability traces. The harness is crucial for ensuring the agent stays up, remains safe, manages costs, and provides visibility for debugging issues. Most of these capabilities were manually implemented in the past but are now being recognized collectively through the agent harness framework.",
  "summary": "This article explains the development and operational layers of an agent harness through two implementations of a finance assistant: AWS AgentCore Harness and LangChain with Envoy AI Gateway. It compares how each handles tools, memory, model access, cost control, and observability, and examines the trade-offs in operational ownership, portability, and engineering effort. By Trista Pan",
