An agent harness is the software scaffolding wrapped around an LLM that turns it into a working AI agent. It handles tool use, memory, state, multi-step loops, context management, sandboxes, and guardrails. The model reasons; the harness lets it act. As the post notes: AI Agent = LLM + Agent Harness.
