Could you build this?
Partial While an agent evaluation harness can be scaffolded via AI, achieving state-of-the-art results on FrontierSWE requires rigorous prompt engineering, advanced tool-use sandboxing, and substantial compute resources.
What it would actually take: The architecture requires isolated container environments (Docker/Firecracker) executing arbitrary codebase patches against rigorous test suites, accompanied by an adaptive multi-step agent loop with specialized static analysis and AST tools. Calibrating the harness requires significant empirical benchmarking compute across thousands of SWE instances and deep expertise in agentic reasoning strategies.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
