This paper proposes a framework for governed runtime evolution in multi-agent systems, formalizing agent-generated code artifacts as persistent runtime capabilities rather than transient outputs. It introduces HarnessMutation, a lifecycle-aware mechanism for runtime adaptation operating under explicit validation, traceability, evaluation, and rollback constraints. The framework models agent self-modification as a bounded, observable, and auditable process over persistent operational memory, building on prior 'Code as Agent Harness' work.
This survey paper introduces the concept of 'code as agent harness,' framing code not merely as output but as the operational infrastructure for LLM-based agents—covering reasoning, action, environment modeling, and execution-based verification. The authors organize the analysis across three layers: harness interface, harness mechanisms (planning, memory, tool use, feedback control), and scaling to multi-agent systems. Applications span coding assistants, GUI/OS automation, embodied agents, scientific discovery, and enterprise workflows. Open challenges include evaluation beyond task success, verification under incomplete feedback, and human oversight for safety-critical actions.
