@Saboo_Shubham_: what an agent harness actually is

Shubham Saboo (@Saboo_Shubham_) sums it up as agent = model + harness, and lists eight parts of the harness: the loop, tools and a sandbox, subagents, context management, memory, guardrails, checking the work, and monitoring. A separate post cites LangChain raising its score on a coding benchmark from 52.8% to 66.5% by changing only the harness (LangChain's figures).

Why it mattersWhen comparing agent products, the model is only half the story. Ask what the harness does about memory, guardrails and checking its own work.
