Adapting the Interface, Not the Model: Runtime Harness Adaptation for Deterministic LLM Agents
Researchers introduce Life-Harness, a runtime interface adaptation method that improves frozen LLM agent performance without modifying model weights. The technique evolves from training trajectories to fix model-environment mismatches, achieving 88.5% average improvement across 126 settings and demonstrating cross-model transferability that suggests environment-side structure matters as much as model architecture.
