// Harness-of-Harness // Exciting new research on coding agents that keep building for days without a human. Here is how it works: Harness-of-Harness wraps whatever coding harness you already run and organizes its executions into repeated planning, coding and testing increments. The loop balances repair against capability growth, scopes work into small verifiable steps, keeps implementation-time testing separate from independent evaluation, and constrains the outputs rather than the workflow. Across GameCraft-Bench, FrontierSWE and ProgramBench with three different harness and model pairs, it averages a 52.25 percent relative gain over the standalone harnesses after three iterations, peaking at 82.86 percent.
