Harness Engineering framework defines agent architecture via state management
October 19, 2026
Agent development is treated as building a program to manage stateless JSON conversation arrays rather than modifying the LLM itself. This approach uses a modular series of patches to solve specific failures in the interaction loop, demonstrated through a 300-line Python implementation.
