Harness engineering extends beyond prompt templates to runtime design
Compared with early agent frameworks, harness engineering additionally includes workflow design (e.g. loop engineering), evaluation, permission controls, and persistent state management — it is closer to runtime and software system design: how the model observes, acts, memorizes, checks itself, and improves.

Harness Engineering for Self-Improvement
Original excerpt
Compared with early agent frameworks , “agent = LLM + memory + tools + planning + action”, harnesses engineering additionally include workflow design (e.g. loop engineering), evaluation, permission controls, and persistent state management . It is no longer only prompt templates, but closer to runtime and software system design: how the model observes, acts, memorizes, checks itself, and improves.
