The framework introduces six key harness capabilities: typed I/O, pass-by-reference tool results, code-as-action, programmable loop engineering, explicit object state, and model-callable APIs. Benchmarks show NOOA achieves 82.2% on SWE-bench Verified with GPT-5.5 (above prior SOTA), 86.8% on CyberGym L1, and 85.1% RHAE on ARC-AGI-3 for under $20/game. Notably, pass-by-reference reduces token usage by roughly half compared to competing harnesses. The framework includes a long-term memory subsystem backed by SQLite with a knowledge graph, and integrates with NVIDIA OpenShell for secure sandboxed execution. ## Full article daily.dev links to this article rather than hosting it.
