An agent harness is the essential infrastructure surrounding an AI model that enables it to perform autonomous actions beyond simple text generation. This harness includes components like orchestration loops, tool connections, memory, context management, and sandboxing. Building these harnesses from scratch is a complex and time-consuming process, often requiring specialized frameworks and significant development effort. Products like Claude Code, GitHub Copilot, Cursor, and Perplexity all rely on sophisticated agent harnesses to function. AI
