Harness Engineering: An Anime Lecture · Harness Engineering: A Stick Figure Lecture · 7 pages · Professor Andy, a friendly anime lecturer inspired by Andrew Ng, explains the shift from prompt engineering to harness engineering: the three-floor stack (prompt, context, harness), the plan-execute-verify-improve loop, context selection and KV-cache hit rates, self-improving loops with memory, and why the model is a brilliant intern while the harness is the management. Adapted from Andrew Ng's Stanford lecture on agentic systems.
