This paper is f*cking brilliant
A computer science paper establishes harness engineering as the primary determinant of AI agent reliability
The result: the ETCLOVG seven-layer architecture unifies execution sandboxes, tool protocols, context state, lifecycle graphs, observability, verifiers, and governance
The crazy part is how harness engineering boosts performance without changing the underlying model
Optimizing the execution harness alone increased SWE-bench coding benchmarks from 6.7% to 68.3%
Most developers try to fix agent failures by upgrading to larger LLMs
This framework shifts system reliability from model weights to deterministic harness architecture
